    We're just a couple months away from MINI showing off the next-generation Cooper at MINI's factory in Oxford, Great Britain. To keep us interested, MINI has revealed the powertrain lineup and chassis for the Cooper.

    The standard Cooper will get a new 1.5L turbocharged three-cylinder with 134 horsepower and 162 pound-feet of torque (170 pound-feet for a few seconds with MINI's overboost function). The Cooper S gets a new 2.0L turbocharged four-cylinder with 189 horsepower and 207 pound-feet of torque (221 pound-feet with overboost). These power figures are thanks in part to TwinPower turbocharging and direct injection from BMW.

    Transmissions are a six-speed manual or automatic. The automatic has a clever trick where it can communicate with the optional navigation system to adapt gear selection to the current route. This sounds similar to what Rolls-Royce is using with the new Wraith.

    Chassis-wise, the Cooper will stick with the damper strut front suspension and a multi-link rear setup. New is a optional adjustable dampers that offer two settings; normal and sport. Steering is a revised electric system.

    Innovative technology for typical MINI MOTORING pleasure:

    • New generation of three and four-cylinder engines
    • All-new chassis technology
    • Passive safety, protection for passengers and pedestrians

    Woodcliff Lake, NJ – September 29, 2013… The latest innovations in drivetrain, chassis and safety will see future MINI models build on their segment-leading position.

    Since 1959, the unmistakable go-kart feeling has been at the heart of the British marque’s DNA. Today, every member of the MINI family has the combination of agile handling, exemplary efficiency, contemporary comfort and uncompromising safety. With the typical innovative strength expected from a premium manufacturer, MINI seeks to set standards for the future in developing vehicles and technologies that transform driving into a unique motoring experience.

    A new generation of engines will once again optimize the balance between driving thrills and fuel consumption. Future MINI models will be the first to use both three and four-cylinder engines, not only covering a broader performance spectrum, but also setting new standards in terms of output, performance, comfort and reliability. The quality of the new engines is a direct result of the unique development expertise of the BMW Group in the area of drive technology. Thanks to the brand and model-specific design, they have performance characteristics synonymous with the MINI motoring experience.

    The advances achieved by MINI in the area of drivetrain technology are characterized by the consistent further development of tried-and-tested design principles and the integration of innovative technology. MINI developers will continue to emphasize sporty, agile handling for all chassis variants.

    In addition, MINI will introduce electrically adjustable dampers for the first time. The electric control of the damper valves will make it possible to vary the nature of responsiveness to uneven road surfaces. Two characteristic curves will be available for damper adjustment that can be activated at the flip of a switch. Depending on the driver's preferences, a sporty drivetrain setting or something more balanced and comfortable can be selected.

    The new generation of engines.

    Maximum motoring fun and the most economical fuel consumption – a two-fold victory in terms of performance and efficiency has helped the latest MINI models to score top marks over their rivals in comparative tests regarding engine technology and driving performance. This is made possible by a new generation of engines and MINIMALISM technologies which will be available in all models as standard.

    For the first time, the MINI models of the future will use both three and four-cylinder engines that not only cover an even broader range of performance, but also set new standards in terms of output, efficiency, comfort and reliability. Both brand and model-specific design ensures that they have performance characteristics typical of MINI.

    More power and lower CO2 emissions thanks to MINI TwinPower turbo technology.

    A common feature of the new drive units is the MINI TwinPower turbo technology, which optimizes both performance and efficiency. In the case of the petrol engines, this technology package includes turbocharging, direct fuel injection, variable camshaft control on the intake and outlet sides (dual VANOS) and, in the more powerful versions, fully variable valve control according to the model of the BMW Group's patented VALVETRONIC system.

    All-new engines were designed for the transverse configuration typical of the MINI and feature a compact and lightweight design. They also comply with exhaust standard EU6. The engines are equipped with an aluminum crankshaft in a closed-deck configuration. A forged steel crankshaft with integrated balancing shaft drive, weight-optimized piston and forged conrod contributes to the high level of performance within the engine through reduced frictional coefficients. The three-cylinder engines each have a countershaft to enhance smooth operation, while the four-cylinder model has two such shafts that counter-rotate. The cylinder head in all engine variants is made of aluminum.

    For the market launch of the new drive generation, MINI is presenting a three-cylinder combustion engine that generates an output of 100 kW/134 bhp from a cubic capacity of 1.5 liters and a 141 kW/189 bhp variant of the newly developed four-cylinder combustion engine that has a cubic capacity of 2.0 liters.

    A new generation of engines with typical MINI performance characteristics.

    All of the new petrol engines feature spontaneous responsiveness, high torque characteristics and supreme power delivery. The 1.5 litre three-cylinder engine reaches its maximum torque of 220 newton meters at an engine speed of 1,250 rpm; this can be increased briefly to 230 newton meters by means of the overboost function. The 141 kW/189 bhp four-cylinder model actually achieves a torque of 280 newton meters with the same engine speed (300 nm with overboost). The maximum speed of all new petrol engines is 6,500 rpm.

    The engine's sporty character is favored by the position of the turbocharger integrated in the exhaust manifold. The short path of the exhaust stream enables the charging system to be activated promptly and effectively. In addition, the emissions pattern of the engines is optimized by the positioning of the catalytic converter and an electronically regulated waste gate. An efficient and precisely dosed fuel supply system facilitates direct injection with centrally positioned injectors between the valves and directly next to the spark plugs. The electronic control for camshaft positioning and the stroke of the intake valves are further technological elements that optimize the responsiveness and the consumption and emissions readings of the new petrol engines for MINI.

    Newly developed manual and automatic gearboxes will further contribute to the intense motoring pleasure that MINI has to offer, and will enhance the efficiency of the drive technology. The new manual gearboxes feature an innovative gear sensor which adapts the engine speed when shifting gears. This permits fast and sporty shifting with always the right engine speed available during gear shifts.

    The automatic start-stop function can also be used in future MINI models in conjunction with the automatic gearbox, avoiding unnecessary fuel consumption when stopped at junctions or when caught in heavy traffic. For cars equipped with a navigation system, gear selection can be adapted to the current route. This way, the suitable gear is selected before reaching junctions or before cornering.

    Chassis Technology.

    Thanks to the continued optimization in the areas of wheel suspension, spring system, damping, steering and braking, motoring is set to become even more enjoyable in future MINI models. In combination with the features so characteristic of any MINI, such as the vehicle's low centre of gravity, wide track gauge, short overhangs, transverse engine, rigid bodywork and intelligent lightweight design, innovative solutions in the chassis area make for even more precise and sporty handling. The agility that characterizes all MINIs is also combined with further advances in the area of driving comfort. This is the first time that MINI is to offer electrically adjustable dampers that can be used to optimize sportiness and driving comfort.

    Tried-and-tested construction principle, completely redeveloped components.

    The complete redesign of the chassis for future MINI models continues to focus on the tried-and-tested structure of the single-link spring strut axle at the front, and the multi-link rear axle - unique among MINI's competitors. It also includes component optimizations in terms of material choice and geometry. The dampers on the front and rear axles are uncoupled from the bodywork by means of complex struts. In combination with the reduction of the unsprung inertial masses, this makes it possible to increase both agility and driving comfort. Newly developed and aerodynamically optimised light alloy wheels are manufactured in a forging process requiring the use of less material.

    In its latest incarnation, the front single-link spring strut axle features increased component rigidity. In combination with a modified axial kinematic movement, this creates ideal conditions for particularly agile manoeuvrability and steering control that is largely freed from the influence of the drive mechanism. The wider track gauge also makes a further contribution to optimizing sporty characteristics.

    Consistency in lightweight design also influenced driving performance. The use of aluminum in the pivot bearing and high tensile steels in the front axle bearing and in the transverse rocker arms reduces the unsprung inertial masses. The innovative torque roll axial bearing enables both agility and comfort to be tangibly increased. This component consists of an engine and a transmission bearing that together absorb the weight of the engine and also support the torque in conjunction with the engine swivel support. The engine block is hydraulically attenuated, further enhancing the increase in comfort because this design prevents the engine from surging under the influence of uneven road surfaces.

    By further developing the multi-link rear axle, MINI is building on its unique position in the competitive field. Key changes – wider track gauge, the use of high-strength steels and greater rigidity in the wheel suspension – take place in tandem with the modifications to the front axle. The spatial design of the rear axle also leads to improved entry comfort and to more space in the rear as well as a larger luggage compartment volume which is also easier to load.

    More precise, more comfortable: electromechanical power steering.

    The next generation of the EPS (Electronic Power Steering) used for MINI models offers speed-dependent support for the steering force. In the future it will take less steering force to operate this, while the system will also meet the requirements for the use of a parking assist function.

    The further development of the steering system will promote agility, driving safety and comfort in equal measure. Thanks to the complex wheel suspension system, the steering ratio can be implemented very directly. Likewise, the optimization of the front axle has a direct impact on the steering, as it facilitates a sensitive steering style when negotiating bends in a sporty style. This effect is further enhanced by the use of so-called torque steer compensation. This torque steering compensation counteracts a tendency towards self-steering in powerful front-wheel drive vehicles due to differences in torque between the right and left front wheels. In the future, active rotational damping will provide for gentler and therefore more precisely controllable vehicle reactions in rapid evasion manoeuvres and when negotiating particularly sporty bends.

    Advanced brake system for more comfort and security.

    Another important contribution to motoring pleasure is derived from the improvements in the function and weight of the brake system, which is more closely tailored to the specific models. The new system impresses with its excellent durability with low unsprung inertial masses. This results in greater comfort, more precise dosability and a longer service life. The efficiency of the MINI can also be increased through targeted innovations in the brake system. Thus, optimized coatings help to reduce the residual braking momentum, thereby enhancing the vehicle's rolling friction.

    Excellent long-lasting properties are achieved through improved surface protection on the disc brake chamber and brake callipers. Another plus point is the optimization of the brake cooling system through refined brake protection plates and a redesigned brake cooling shaft.

    A first for MINI: adjustable dampers.

    In an effort to emphasize the MINI character even more, the spring and damper adjustment will be optimized. On the front axle, spring struts made of aluminum and steel and two-pipe compression dampers with coated pistons and a degressive damper characteristic curve are used. The support bearings on the front and rear axles will have three paths in future. The characteristic curves of the support bearing and additional springs have also been optimized on a functional basis, as have the helical springs installed on both axes. The stabilisers on the front and rear axles have holdings bearings and will have a tubular design, helping to reduce weight in the chassis area.

    In addition, MINI will be introducing adjustable dampers for the first time. The electric control of the damper valves allows the characteristic response to uneven road surface to be varied. Two characteristic curves are available for adjusting the damper and these can be activated at the flip of a switch. The traction and compression level in the shock absorber can be adjusted by selecting the appropriate setting. Depending on the driver's preferences, it is possible to choose either a sporty or a balanced, comfortable chassis. This means that it is possible to enjoy greater driving comfort in poor road conditions or a sporty driving style on an even road surface.

    Passive safety, protection for passengers and pedestrians.

    Premium vehicles by MINI hold an excellent position within their vehicle class not just in terms of motoring pleasure, but also in the area of passenger protection. In the event of a collision, precisely defined support structures and generously proportioned crumple zones help to protect the passenger cell while highly efficient restraint systems offer MINI passengers optimum protection in all types of crashes.

    Top scores in international crash tests confirm the effectiveness of the overall concept for maximum passive safety, which is under continuous development for new models to ensure that the latest standards are met. In addition, innovative solutions in the area of pedestrian protection are also being developed for future MINI models, helping to reduce the risk of injury for other road users.

    Reduced weight and increased safety thanks to intelligent lightweight construction.

    The focus of developments in the body area is on structural improvements that have a positive influence on both driving features and crash performance. Intelligent lightweight construction enables MINI to combine the reduction of weight with an increase in rigidity and this promotes both agility and passenger protection. The use of second generation high-strength multi-phase steels plays a key role. Their excellent forming properties allow for much more complex structures than would be possible with conventional materials, while still permitting no compromise on strength. Parts that are of particular relevance to structural rigidity are made from micro-alloyed steels. In addition, hot-formed steels are used in the safety-related zones.

    So-called tailored welded blanks and tailored rolled blanks also contribute to the optimization of weight. Welded and rolled sheet metal joints are widely used for the first time in cars from the small vehicle segment. The reinforcement of the B pillars with a coating of galvanised, hot-formed steel, which acts as a cathodic anti-corrosion finish, means that additional, weight-increasing measures could be dropped.

    Despite the reduced weight, the intelligent mix of materials for the highly resilient support structures in the front and rear and in the roof and side frame. In the event of the vehicle rolling over, the reinforced pillars and roof supports secure the survival space of the passengers even more intensively than ever. Reinforced structures in the B pillar and sill area, high-strength side impact bars in the doors and stable seat braces will further minimize the degree of deformation and the speed of intrusion in the event of a side impact.

    This concept establishes the right conditions for maintaining the passenger cell as a survival space in a wide variety of accident scenarios and forms the basis for the high level of effectiveness of the restraint systems. The integrated safety electronics ensure that the triggering of the airbag and belt systems is adapted to the type and severity of the accident. The coordinated interaction of all components ensures the best possible protection, irrespective of the position of the passengers at the time of impact.

    Crumple elements on the front for extensive pedestrian protection.

    The front section of future MINI models will have extra crumple elements. In addition to the yielding sections of the engine cover, a shock absorber between the bumper bracket and the cladding is intended to reduce the risk of injury. The pedestrian protection system will also be part of the standard equipment supplied with new MINI models.

    2.0L is a bit of a surprise, but BMW has been hard at work to adapt 2.0L blocks to the MINI's engine bay (as exemplified by the Cooper SD here in Europe)... Also, wonder if the JCW will go over 230HP this time around...

    Guess the small bump from 181 to 189 might make a difference, But more noticable will be the bump in Torque from 177 to 207.

    Since the JCW is 208hp / 192lbs or 207 with over boost. It will be interesting to see just how much more they bump it up for the JCW version.

    I hope the Adam comes over as a Buick with AWD and a nice Torquey motor.

    • @oldshurst442 Thank you for the kind words.  Is it okay if I laugh about part of the post?  I own being a real nerd when it comes to certain topics.  For one, I am fascinated by geography and always have been.   One life shaping event was moving back (and forth) to Europe 2 times with my parents before I was a teenager.  That involved crossing the Atlantic on the few ships that were still doing that voyage and even crossing America on Amtrak from the West Coast to the NYC suburbs, where we stayed with relatives for a few days before boarding for the sailing.  So, by the time you are 8 years old, and you can study maps, I was able to trace the ocean crossing - seeing the ports we stopped in as well as the Azores, which you sail through - as well as the train trip across the U.S.  Every place looked different.  So did the people.  But, mostly, the scale was staggering, when you compare it to going from L.A. to Las Vegas, or even N.Y. to Miami. My dad also contributed to this.  Before being allowed to come to the U.S., he moved to Australia, as did others from Mediterranean countries.  Australia was sort of open at the time and he got in.  He stayed 3 years.  He did not like it.  He also took the ship to and from Australia.  That trip is 3x as along as crossing the Atlantic.  You go through the Suez Canal, the Red Sea, and then cross the Indian Ocean along South Asia and then down to Australia.  I heard about all this and saw photos from these journeys.  I'm glad he didn't like Australia!  I much preferred growing up in the U.S. Cars and planes were such an evolving "art form" when growing up.  Both had a lot of personality and kitsch that's lacking today.  Yes, there was less worry about the environment, sustainability, and global warming.  So, ignoring that, cars were going for new styling frontiers, crazier interiors, and bigger engines.  And I loved following all that, and even sketching it up at times.  The same was true for planes.  We lived about 6 miles from the international airport and I would ride my bike there, just to be at the airport and look at all the planes and even the different airport buildings.  The 747 kept getting updated and better.  The L.A. Times would always have big ads for the different airlines and their gimmicks, including a Hawaiian styled lounge in the coach section from the West Coast to Honolulu on certain Continental 747s!  How cool is that?  I would tear out some of these newspaper ads and keep them.  You were very likely to fly from L.A. and S.F. to N.Y. or Chicago on 747s.  In fact, it was fun to look at their schedules and find those odd trips where the transcontinental trip had another leg on it so, just maybe, you could fly on a jumbo jet somewhere close, like to San Francisco for 45 minutes.  But kids and teens couldn't take trips like that, unless you convinced your parents to go, too. The above is absolutely hilarious by today's standards but, when you're a kid, you took it for granted.  This is on a Continental 747 ... in "coach."  Today, losing this many coach seats to a "lounge" would never pencil and you'd be attracting the bar flies.  But, maybe that would be better than having people on planes being hostile to flight attendants and each other.  We didn't hear much about that when I was a kid. The above is American Airline's rendition of the 747 coach lounge.  This is nuts, including facing sideways and backwards.  That lady looks like Jill St. John. The above is upstairs in first class, again on a Continental 747 ... another kitsch laugh riot. "Those were the days" because I don't think that, despite so much progress, QOL is much better in the last decade or so. @Robert Hall also has interesting stories and I like hearing about the compare-contrast between living in the Desert Southwest and the Rocky Mountain states, especially since both have pipelines of people going to and from California.  And, along with many others, how people originally from the Eastern Time Zone headed the call to "go West" and what that was like.   Stories about immigration and transplantation fascinate me.  I'm all ears for those.
    • I would agree. While the truck is built in the U.S. and many parts are supplied by U.S. companies, the profits return to Japan to a Japanese corporation. I find this a contradiction that I am seeing allot this fall which I think is due to it being a mid-presidential term election year. I wonder how people can be on this Beat the American Drum kick and yet their own buying habits contradict their statements. On the October spotting, there must be a local old car get together somewhere around here locally on Sunday as I just ran an Errand to Home Depot and on the way home, half a dozen old autos were following each other up highway 99 here.
    • The Tacoma is built in San Antonio but still a whole lot of contradiction there lol.
    • Saw two things this morning while running errands. First was a very old Chevrolet Suburban from the 1950's era in the process of being restored. It was on a trailer being towed someplace while I was driving on I5. Second thing was a Toyota Tacoma that had an interesting bumper sticker.  Pro-America Buy America Anti-Trump So not a political statement or discussion I want to start, but I am interested in what others think is meant by the Pro-America/Buy America part of this.  IMHO I find this a contradiction that they are driving a Toyota with that part of the bumper sticker. Thoughts?
