    2015 Chevrolet Corvette Z06 Is The Most Powerful Production Corvette EVER!


    • Chevrolet Announces The Performance Figures For The 2015 Corvette Z06


    Five months after Chevrolet revealed to the world the 2015 Corvette Z06, the brand has announced the final performance numbers and they are impressive to say in the least. When the model was revealed at the Detroit Auto Show, Chevrolet said the Z06 was producing 'at least 625 horsepower', but they needed to do final testing to get the ratings. Well, the Z06's supercharged 6.2L V8 has been SAE-certified and is rated at 650 horsepower and 650 pound-feet of torque. Not only is this the most powerful production Corvette, it also happens to be the most powerful production model ever built by GM.

    To put those numbers in perspective, the Z06 is bested by models such as,

    • Ferrari LaFerrari
    • McLaren P1
    • Porsche 918 Spyder
    • Ferrari F12 Berlinetta
    • Lamborghini Aventador
    • Ferrari FF

    More impressive is the stats for torque. At idle, Chevrolet claims that 457 pound-feet of torque is available, and that 96 percent of peak torque arrives by 2,800 rpm.

    “The LT4 small block sets a new benchmark for power and torque at GM,” said Steve Kiefer, vice president, GM Powertrain Engineering. “The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving.”

    2015 Corvette Z06 Rated at 650 Horsepower

    Supercharged LT4 V-8 engine is the most powerful ever from Chevrolet

    DETROIT – The all-new 2015 Corvette Z06 is the most powerful production car ever from General Motors and one of a few production cars available in the United States that delivers more than 600 horsepower.

    The Z06's LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm.

    "The LT4 Small Block sets a new benchmark for power and torque at GM," said Steve Kiefer, vice president, GM Powertrain Engineering. "The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving."

    Compared with other supercar engines, the LT4 is a veritable fountain of low-end torque, producing 457 lb-ft (619 Nm) just off idle and 625 lb-ft (847 Nm) by only 2,800 rpm. The V-12-powered Ferrari F12 Berlinetta, for example, produces about 28 percent less torque than the Z06, despite offering about 12 percent more horsepower – and its peak torque isn't achieved until 6,000 rpm. The LT4 maintains 90 percent of its peak torque, or 592 lb-ft (802 Nm), from 2,500 to 5,400 rpm.

    The new LT4 engine eclipses the Porsche 911 Turbo S engine's peak power levels by 90 horsepower (67 kW) and 134 lb-ft of torque (182 Nm).

    "Torque is the pulling power of an engine and the LT4's abundance of it at every rpm in the engine's speed range helps the 2015 Corvette Z06 accelerate quicker and respond nearly instantaneously," said Jordan Lee, chief engineer for Small Block engines. "It's the very definition of power on demand."

    The new Z06 engine produces 40 percent more peak torque (180 lb-ft / 244 Nm) than the previous-generation's 7.0L LS7 engine – and 7.5 percent more than the supercharged 2013 Corvette ZR1's 604 lb-ft (819 Nm). At 3,200 rpm, the new LT4 surpasses the LS7 by 208 lb-ft of torque (252 Nm). On the horsepower side of the graph, the LT4's 650-hp rating is 29 percent greater than the LS7's 505 horsepower (376 kW), and 12 horses more than the ZR1's LS9 engine.

    "The new LT4 engine builds on the design strengths of our previous supercharged engine and leverages the technologies introduced on the Corvette Stingray – direct injection, cylinder deactivation and continuously variable valve timing – to take Corvette performance to an all-new plateau," said Lee. "Our new, very compact supercharger also helps the engine make power more quickly, and perhaps more importantly, it helps produce more torque earlier in the rpm band."

    "It's also worth mentioning that the LT4's supercar performance numbers are achieved with an engine that is nearly the same size as the very compact LT1 engine introduced in the 2014 Corvette Stingray," Lee said. "The power density of the LT4 makes it one of the smallest and lightest 650-hp engines in the industry."

    LT4 details

    The new LT4 engine is based on the same Gen 5 small block foundation as the Corvette Stingray's LT1 6.2L naturally aspirated engine, incorporating several unique features designed to support its higher output and the greater cylinder pressures created by forced induction, including:

    • Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional aluminum heads

    • Lightweight titanium intake valves

    • Machined, forged powder metal steel connecting rods for reduced reciprocating mass

    • High 10.0:1 compression ratio – for a forced-induction engine – enhances performance and efficiency and is enabled by direct injection

    • Forged aluminum pistons with unique, stronger structure to ensure strength under high cylinder pressures

    • Stainless steel exhaust manifolds and an aluminum balancer that are lighter than their LT1 counterparts

    • Standard dry-sump oiling system with a dual-pressure-control oil pump.

    A new 1.7L supercharger spins at up to 20,000 rpm – 5,000 rpm more than the supercharger on the Corvette ZR1's engine. The rotors are smaller in diameter, which contributes to their higher-rpm capability – and enables them to produce power-enhancing boost earlier in the rpm band. That boost is achieved more efficiently via a more direct discharge port that creates less turbulence, reducing heat and speeding airflow into the engine.

    "The Small Block's cam-in-block design heritage has always enabled very high performance and responsiveness in a small, compact package – an attribute amplified by the performance of our new supercharger's design," said Lee.

    The LT4 is assembled at the new Performance Build Center at GM's Bowling Green Assembly Plant and at GM's Tonawanda engine plant in New York. It is matched with a standard seven-speed manual transmission or an all-new, paddle-shift eight-speed automatic transmission built in Toledo, Ohio.

    Designed to deliver shift responses on par with the world's best dual-clutch transmissions, it is the first automatic offered in a Z06. It also makes the Z06 one of the few cars this powerful to offer the choice of a conventional manual transmission or an eight-speed automatic.

    The 2015 Corvette Z06 goes on sale in early 2015.

    That is the idea. Hopefully, with a 7-speed manual.

    "Impeccable manners that make it suitable for daily driving." - Cool, as long as they say I can use it for a grocery getter, that's good, OK, I will get one then. Cool, just wanted to make sure...OK, whew...! OK, that's good....How much are these anyways?

    It's a given the top of the line car will be above $100,000 as C6 Z06 LZ3 with Z07 package rang $103,000.

    Just wait till Hennessey gets his hands on this corvette. I wonder how much HP / Torque he can get out of it.

    A ton of power to be sure, but you have to put it on the ground also.

    The McLaren P1 and Porsche 918 are truly different animals, those cars can lap the Nurburgring in under 7 minutes with ease.

    According to nurburinglaptimes, the '12 Corvette ZR1 posted a 7:19.63, and the '13 nissan GTR (AWD) posted a 7:19.10.

    It's getting the power down totally on par with AWD (which is I assume your implication). No worries.

    With only 3 cars ever going below 7 min on the tack and the rest all bunched up by just a few seconds, most people will never know the difference and just say WOW what an awesome ride.

    Top 100 Track times.

    http://nurburgringlaptimes.com/lap-times/lap-times-top-100/

    #1 Radical SR*LM 6:48 Model yr 2009

    Further, the last time an F1 car ran the track, in 1976, it posted a time of 7:10.8.

    No doubt he was slowed down worrying about 'putting the power down' in his RWD-only car.

    The Corvette gets its power down, the ZR-1 seemed to just fine, but at some point you reach a bit of a limit for a rear drive road car. Unless you create a car with a ton of down force like a Formula 1 car has. That is why the 700-900 hp hyper cars are mostly AWD. Although the Koenigsegg is RWD.

    On a side note, I'd like to know what kind of time the Mercedes Formula 1 car sound run the ring at now, because their car is tearing up F1.

    GM's Video is freakin awesome as they talk about all the features and details. The new 2015 Z06 is equal to the old Z01 or so they say but the new supercharged v8 has no connection to the old LS9 Supercharged V8. So does this make this an LS10 engine?

      If it weren't for focus groups, the design of the 2018 Chevrolet Equinox could have looked so much different.
      Speaking to Automotive News, chief engineer of the 2018 Equinox Mark Cieslak revealed that focus groups weren't not impressed with the first designs of the redesigned model. They described the design as being bulky, 'not compelling', and looking a bit odd. If this was old GM, they would have gone forward with the design.
      "Back in the day, we would have probably just kept going," said Cieslak.
      "What we had on paper we felt was not going to win."
      But this being the new GM where bean counters lost a fair amount of influence, the decision was made to go back to the drawing board. At the time, GM was scrambling to fix the Malibu as its redesign earned poor reviews and a drop in sales which likely played a part in this decision. They needed to get the Equinox redesign right as the model it would replace was very popular. There were concerns that this could cause the new Equinox to be delayed. But in the end, the team were able to design a new Equinox without falling off schedule.

      Tesla Officially in Trouble, Business Insider Says!

      To quote Business Insider final comments on Tesla and the Chevy Bolt:
      "Clearly, Tesla would be in less trouble if the Chevy Bolt were a bad car. But it isn't. Teslas have always blown me away. The Bolt blew me away for different reasons. I just hope Tesla is prepared to take this into account." 
      Matthew is a Business Insider senior correspondent who covers transportation and as a fan of Tesla was excited to check out a Chevy BOLT as comparison to the Tesla. On a recent trip to california he took time to visit the closet Chevrolet Dealer to his hotel and this is what he found.
      He states that to borrow Barkley's line, "Tesla is in trouble." You have one of the world's biggest auto companies that is known for killing the electric auto stepping off the sidelines and actually committing considerable resources to building a long range EV where it can afford to lose money on it long term till the market changes. Tesla has 400,000 plus pre-orders, but is burning through cash by the billions and while the launch of the Tesla 3 is near and Tesla still has Sexy much like Apple to an iPhone. Tesla does not have the depth of customer auto experience to pull from and as the author points out, Tesla balance sheet is precarious as it is based on raising funds on a growth story. The author goes onto say that no one will cross shop a Tesla S or X with the Chevy BOLT. They will due to limited options cross shop the Tesla 3 to the Bolt.
      To pull some interesting statements from the story, the author had the following to say:
      "I found it more fun to drive than both the Tesla Model S and the Model X, but not the original Roadster, a much smaller vehicle."
      "The Bolt is plenty fast for most people."
      "GM isn't going to overwhelm Tesla with Bolt sales. I actually think the Model 3 will greatly outsell the Bolt once Tesla's car arrives. However, it's also possible that if the Model 3 is delayed or is slow to ramp up, Chevy will be preparing a mid-cycle refresh of the Bolt before Model 3 sales start to achieve some major momentum. In other words, GM will always be ahead, and the company — barring another massive financial meltdown — will never stop putting the Bolt up against the Model 3."
      BI covered the BOLT in follow stories with the next one being more of an official review that starts off with covering the auto with the following statement: "A platform, not business as usual!" 
      From ride-hailing to ride-sharing, self driving Chevy has delivered an auto for the future that gives GM options on how they build and expand their EV lineup. BI took delivery of their white Premier BOLT just before the blizzard that hit NY. Clearly a compact-crossover-hatchback look, design is what the magazine employees felt it was and is. Surprising the BI reviewers was the amount of cargo the auto can hold and how well it handled 4 people and grocery getting. BI states that GM has told them the next addition to the BOLT lineup will be a larger auto that can accommodate 5 or more people. An exceptionally well executed minimalist design that comes with an interior that feels more premium in comparison to auto's this size in the past from GM that felt clearly parts bin cheap. The review goes on to talk about how setting the front seat for a 6'4" tall driver and getting in the back with room ahead of the knees for the same size person is a nice welcome addition to such a compact auto. Heated steering wheel was welcomed by all. Apple CarPlay and Android Auto kept everyone happily connected to their phone while driving.
      The final statement to quote from the review is as follows:
      "We were impressed with the Bolt, as a car, as an electric car, and as a mobility concept. In many ways, it is GM's post-bankruptcy masterpiece, a real feather in the cap of CEO Mary Barra and her executive team, who took what the company had achieved with its ill-fated EV-1 back in the 1990s and turned it up to 11. 
      I also flat-out loved driving it. I blasted in and out of New York City twice, rocketed around the streets of Gotham, darting through traffic, and cruised along the highways of New Jersey. I also enjoyed just driving it around the quiet streets of the suburb where I live.
      The steering is quick and responsive, and the handling is sharp enough to provide the confidence you need when surfing that sweet EV torque.
      The single-pedal mode is also very cool — I dug not using the brakes at all for extended excursions in my town. After a bit of practice, you get into a kind of Zen state with it. 
      Not a single person asked me about the car, and that can be chalked up to the ho-hum design. But I didn't care. I was lovin' it. Plain and simple, the Bolt is fun."
      Here is where we have overlap between story #2 and Story #3 which covers the 7 Killer Features:
      Dual Screens- 10.2" touch screen infotainment center & an 8" drivers console display which are totally customizable. Auto's wireless charging console. BOLT App allowing you to be connected to your auto at all times. Five cameras: front, rear, side mirrors and their 360 camera. 9hr full charge time from a 240 volt charger. 25 miles per hour, faster with Level 3 DC charging. Lane Keep assist feature. Modern Seat design allowing for maximum space inside. Over all these writeups show that GM has delivered a superior auto to the Prius, Leaf, 500e, etc. The future will be bright for the BOLT as GM move the platform forward.

      The Camaro Z/28 will be returning for an encore act and it might be using the next-generation of Chevrolet's small-block V8.
      Car and Driver reports that GM is working on the next-generation LT engines, codenamed LT6 and LT7. These new V8 engines will lose the pushrods and two-valve combustion chambers that have been a key part of the small-block V8. Instead, the new engines will feature dual overhead camshafts, four-valve combustion chambers, flat crankshaft, titanium connecting rods, and possibly dual injection (port and direct). For the Z/28, a 5.5L LT6 could produce 700 horsepower (that's without any sort of forced induction). 
      Car and Driver speculates there could also be a twin-turbo LT7 that could be used in the next Corvette, high-performance Camaros, and Cadillacs.
      The Camaro Z/28 could arrive next year as a 2019 model year vehicle.
