Audi Brings 4 Plug-In Hybrids to Geneva: Comments

Recommended Posts


Audi is showing its expanded range of plug-in hybrids at the Geneva Auto Show next month in Switzerland.  The models gaining the new plug-in variant are the A6, A7, A8, and Q5. 

The heart of the new Plug-In hybrids is a new 14.1 kWh lithium-ion battery that offers up to 40 KM (25 miles) of electric only range. When battery power is exhausted, the turbo direct-injected gasoline engine kicks on.  Energy recuperation is split into 3 modes. Light deceleration is managed by the electric motor, medium deceleration is a combination of electric motor and the hydraulic brake system, heavy deceleration over 0.4 g is handled entirely by the brakes. The hybrid side of the braking system can recover up to 80 kw of electricity.

Charging one of these new Audi Plug-Ins is done via a compact charging system.  At a 7.2 kW charger, a full battery charge happens in about 2 hours.  Audi's e-tron charging service grants drivers access to charging stations in 16 European countries, and Audi will support customers in getting an electrician to install a power station in their garage.  

The myAudi app will allow owners to manage their car charging from their phone. The app will show charge status, range status, program a charging timer, and view consumption statistics.  A further convenience function is being able to remotely control the heating and air conditioning system to pre-heat or pre-cool the cabin before departure while the vehicle is being charged.  The vehicle's HVAC system runs off the high voltage battery pack. 

The A6, A7, and Q5 will be available in two power output levels depending on trim line.  No specs have been released yet.

The Audi A6, A7, A8, and Q5 Plug-In hybrids will be available for ordering in Europe later in 2019.  No word yet if they will be released in the U.S.

Efficient and Powerful: The New Plug-In Hybrid Models Audi Q5, A6, A7 and A8

 

  • Audi A8, A7 Sportback, A6 and Q5 as plug-in hybrids with a strong electric motor, high battery capacity and a new drive strategy
  • An electric range of more than 40 km according to WLTP
  • Convenient and networked charging with myAudi app

In electric-only mode not just free of local emissions but also efficient and sporty – Audi is consistently pursuing its electrification strategy with its comprehensive plug-in hybrid offensive. Audi is presenting the hybrid variants of the models A8, A7 Sportback, A6 and Q5 with an electric range of more than 40 kilometers in the WLTP cycle at the Geneva Motor Show. Thanks to different output levels, the customer has the choice between a comfort variant and a performance variant with a sporty design, depending on the model series. The new plug-in hybrid models will be available for order during the course of the year 2019.

 

Wide selection of models: The plug-in hybrid strategy of Audi
Plug-in hybrids from medium-size SUV to luxury sedan – with Q5, A6, A7 and A8 TFSI e, Audi is expanding its range of plug-in-hybrids for sustainable mobility. Depending on the model series, there is a choice of two variants with different performance and equipment: A comfort model and a variant with a sporty configuration with S line scopes, a more tightly tuned suspension and drive setup with higher boost performance of the electric motor for more dynamic handling. From now on, the new plug-in hybrid models carry the “TFSI e” signet. In the future, the “e-tron” label will remain reserved exclusively for electrically driven cars.

Power from two hearts: the versatile drive concept
The plug-in hybrid electric vehicles (PHEV) create enthusiasm thanks to their versatile character. In electric-only mode, for example, free of local emissions in the city, no range anxiety when driving long distances, sporty and dynamic with the with the power of two hearts from the combustion engine and electric motor: The drive concept offers a wide range.

The electric-only range of the PHEVs will account for more than 40 kilometers in the WLTP cycle for every model. The hybrid drive concept is designed so that customers can travel on around a third of their usual routes in electric-only mode during day-to-day driving.

All new plug-in-hybrids by Audi use a turbo-charged gasoline engine with direct injection that works together with an electric motor that is integrated in the transmission. A lithium-ion battery beneath the luggage compartment floor supplies the electrical energy. As a result, the electric motor can support the combustion engine during acceleration. The result: high start-off performance and powerful acceleration.

At the same time, with regard to recuperation, the drive system resembles that of the new purely electrically driven Audi e-tron*. It is designed for high efficiency and maximum recuperation performance. When breaking, the new Audi PHEV models recover up to 80 kW of energy. The electric motor handles slight decelerations, i.e. the majority in everyday traffic. For medium brake applications, the task is divided between the hydraulic wheel brakes, which perform this task alone only with a deceleration of more than 0.4 g.

The lithium-ion battery for the A6, A7 and A8 is made up of 104 pouch cells, which are combined in eight modules. It stores 14.1 kWh of energy at a voltage of 385 V. The lithium-ion battery in the Q5 comprises prismatic cells and has the same capacity. In each case, the cooling circuit of the battery is integrated in the low-temperature circuit, which supplies the electric motor and the power electronics. The power electronics transform the direct current of the high voltage-battery into a three-phase current for the electric motor; when recuperating, it does the opposite. The standard heat pump ensures efficient vehicle climate control and can generate up to 3 kW of heat energy from 1 kW of electrical energy with the waste heat occurring in the vehicle.

The powertrain: efficient combustion engine, high-performance electric motor and large lithium-ion battery capacity
The A8 with plug-in hybrid drive has a combustion engine and a permanently excited synchronous motor as an electric motor. It is integrated together with the clutch in the eight-gear tiptronic, which passes the torques to the quattro permanent all-wheel drive. The luxury liner drives as a 5.3-meter long A8 L variant with an extended wheelbase.

The Audi A7 and A6 models with plug-in hybrid drive use the same powertrain. The battery capacity is identical to that of the Audi A8 PHEV. Together with the electric motor that is integrated in the dual clutch transmission, a gasoline engine ensures that there is ample output and torque. Both models are available in two output levels with different boost performance.

The powertrain in the Audi Q5 PHEV follows the same concept as the Audi A6 and A7.

Drive modes and drive control: Maximum comfort and high electric range
The hybrid management of the plug-in-models is designed for maximum efficiency and customer comfort and automatically selects the optimum operation strategy. Start takes place electrically in “EV” mode as standard; the combustion engine is switched on depending on the situation.

The plug-in hybrid models have the following drive modes: “EV,” “Auto,” and “Hold.” With the operating mode button, the driver can select from these three basic settings: Priority for the electric drive, fully automatic hybrid mode or save power for a later phase of the journey. In “Auto” mode, the PHEVs use the intelligent interaction of the electric motor and the combustion engine for maximum efficiency. In “Hold” mode, the drive management controls the powertrain so that the current charge status of the battery is maintained, e.g. for driving later in electric-only mode in urban areas.

The predictive efficiency assist makes an essential contribution to increasing the electric range and ensuring maximum customer comfort. For this purpose, the intelligent drive management integrates the route profile into the control of the powertrain. The predictive operation strategy assesses both the navigation data during active route guidance and the information of the predictive efficiency assist as well as of the vehicle sensor system. Using this information, it creates rough planning for the entire route and fine planning for the upcoming kilometers. As a result, situations are recognized in which the driver should take their foot off the right pedal. The driver receives a corresponding visual indication on the display and haptic feedback via the active accelerator pedal. At the same time, anticipatory recuperation is initiated.

Moreover, the driver can select between the “comfort,” “efficiency,” “auto” and “dynamic” drive modes via the familiar switches in the Audi drive select dynamic handling system and thus influence the setup of the drive, suspension and steering. Depending on the setting, the thresholds from which both drives work together or the electric motor supplies the boost and thus the maximum torque change when accelerating. In “dynamic” mode, the electric motor supports the combustion engine more intensively with its electric boost performance for maximum dynamic handling.

The active accelerator pedal with variable pressure point for driving in electric-only mode supports the drive with haptic feedback for operation that is as efficient as possible. When the driver removes their foot from the accelerator, the vehicle glides freely in the automatic gear D and in the Audi drive select profiles “auto” and “efficiency” (under 160 km/h), where both the combustion engine and the electric motor are decoupled and switched off. On the other hand, in the S gear and in the “dynamic” profile, the electric motor remains active in deceleration mode and recuperates, i.e. it converts the kinetic energy into electrical energy.

The optional Audi virtual cockpit and the MMI display present all important notifications concerning electric driving: a power meter, the range and all energy flows.

Versatile – not only with regard to the drive: Model strategy and equipment lines
Audi offers the A6, A7, and Q5 each as comfort models and sporty and dynamic variants. The latter are being launched with particularly sporty equipment: Apart from the increased boost of the electric motor, they have an S line exterior package as standard. In addition, the A6 and A7 have a black styling package with darkened trims, brake calipers painted in red, and privacy window glazing in the rear compartment. The performance hybrids also place sporty touches in the interior. The A6 and A7 have a sport suspension as standard.

Convenient: Charging with the e-tron Charging Service
The compact charging system is also part of the standard equipment of the new Audi plug-in hybrids. It comprises cables for the domestic and industrial sockets and a control panel. 
As an option, Audi supplies the wall-holder clip and a mode 3 cable for public charging stations. At a charge connector with an output of 7.2 kW, a full charge of the battery takes a good two hours.

While on the go, customers can charge the new plug-in hybrid models conveniently. A charging service owned by Audi, the e-tron Charging Service, grants access to a large number of public charging stations in 16 European countries on request. Preparations are being made to introduce this in other countries. Just one card is sufficient to begin charging with numerous providers. Customers have to register one time on the myAudi portal and conclude a charging contract that is subject to a fee. Invoicing always takes place at the end of the month using the stored method of payment.

At the market launch of the Audi e-tron*, Audi customers can supply their house and their garage with eco-electricity, generated free of CO2 emissions, from the “Volkswagen Naturstrom” brand. It is generated 100% from renewable sources, such as hydroelectric power plants, and its origin is certified by TÜV every year. In addition, if necessary, Audi supports customers in getting them in contact with an electrician for implementing a suitable charging solution in their own garage.

Charge Management from the Couch: The myAudi app
The myAudi app is also a practical tool for dealing with the vehicle. The app brings services from the Audi connect portfolio to the customer’s smartphone. Using the app, the customer can remotely check the battery and range status, start the charging process, program the charge timer and view the charge and consumption statistics.

Another function of the myAudi app is the pre-entry climate control even before setting off. It is made possible because the compressor of the air conditioning and the auxiliary heater in the vehicle work on a high-voltage basis. The customer can determine exactly how the interior should be heated or cooled while the vehicle is parked or the battery is being charged. Depending on the respective vehicle equipment, heating of the steering wheel, seats, mirror, windshield and rear window as well as the seat ventilation can be activated via the pre-entry climate control. Rapid start of the climate components is also possible when unlocking the vehicle with the key.

yeah, it is a bit of a head scratcher on the battery pack. Maybe there isn't enough room in the car in these platforms that weren't designed from the start to be hybrid. MLB was designed for first release to the public way back in 2007, so maybe there needs to be an MLB update to support hybrids better.

      After 20 years, Audi will be sending off the TT coupe and convertible into the great parking lot in the sky. During the brand's annual meeting today, Audi CEO Bram Schot said a new strategy focusing on sustainability means the brand has to cut a number of models that don't make economic sense.
      “There will be lots of things that we won’t do any more in the future, or things that we do less. We focus maximum resources on our key projects,” said Schot.
      This is part of an effort to get the brand back on track in terms of sales and profit after the diesel emission scandal which culminated in the arrest of former CEO Rupert Stadler and an 800 million euro ($895 million) fine.
      Schot did reveal that the TT would be replaced by a new "emotive" electric vehicle in the same price range. No other details were given.
      The TT isn't the only model on the chopping block. The R8 sportscar is being questioned as to whether or not it fits into Audi's new focus. Also, the successor to the A8 flagship may go all-electric.

      Ford unveiled the completely redesigned 2020 Ford Escape today ahead of its official showing at the New York Auto Show in two weeks.  Some of the biggest news about the Escape comes under the hood where 4 new powertrains debut. 
      The standard engine will be a 1.5 liter Ecoboost 3-cylinder that can run as a 2 cylinder during light load situations.  The engine is projected to produce 180 horsepower and 177 lb-ft of torque when fueled with premium gas. This is the first Ford engine with cylinder deactivation. The engine will be standard issue on S, SE, and SEL level trims. When properly equipped, the 1.5T will tow up to 2,000 lbs. 
      For those wanting more power, the Titanium trim will have a 250 horsepower, 275 lb-ft Ecoboost displacing 2.0 liters and coming standard with AWD. When running 93 octane, Ford says it will propel the Escape to 60 10% faster than the outgoing model. Towing for the 2.0T is maximum rated at 3,500 lbs. Both Ecoboost engines send power to the wheels via an 8-speed automatic.
      For the Eco-minded the hybrid returns to the Escape lineup after a 7 year absence, also joined by a plug-in variant.  The Plug-in uses an all new 2.5 liter 4-cylinder Atkinson cycle hybrid engine paired with a CVT.  The combined output of the hybrid is rated at 198 horsepower and is capable of 85 mph in electric only mode. The hybrid will be available only on the SE Sport and Titanium trim.
      The Plug-in hybrid will be available on SE, SEL, and Titanium trims. It will have an electric only range of 30 miles. Level 1 and Level 2 charging are available. Level 1 110 volt outlet takes 10 to 11 hours for a full charge from empty, switching to level 2 cuts that time to about 3.5 hours. Total system power increases over the standard hybrid to 209 horsepower, but will not be available with All-wheel drive. 
      Both hybrid models feature 4 EV modes that allow the driver to adjust drive settings to the most suitable for conditions and needs.
      Auto EV mode - the vehicle decides whether to run on gasoline or electric power. EV Now Mode - the vehicle operates on all-electric drive. EV Later Mode - the vehicle operates on gasoline power to conserve electric miles for later EV Charge Mode - the vehicle operates on gasoline and recharges the battery for later EV only mode. Helping on the efficiency front, Ford designers made the most aerodynamic Escape ever.  They made a more sloped roofline and strake, an efficient underbody, and an optimized liftgate spoiler. Overall, the 2020 Escape is 200lbs lighter than its predecessor.  The new Escape is longer, lower, and wider than the outgoing model. The two ecoboost engines boast a range of 400 miles per tank, while the standard hybrid with FWD aims for a range of 550 miles. 
      Inside, Ford engineers optimized space to increase headroom and cargo capacity.  With the second row in the fully forward position, the rear cargo area can accommodate 4 golf bags or a full size dog crate. 
      On the safety front, the Escape comes with Ford Co-Pilot 360 standard.  Other technologies like Adaptive Cruise and Lane-Centering are available.  Passengers are entertained via an 8-inch touch screen standard on SE and above. The gauge cluster is a 12.3 inch all digital system that uses 3D animated graphic to indicate drive mode. 
      The 2020 Ford Escape will reach dealers in the fall with the Plug-in Hybrid variant due in Spring 2020. 
      We will have more of the 2020 Ford Escape from the New York Auto Show on April 17th.
