2010 Audi A8 hybrid

to the A1 e-tron . Audi also a hybrid version for the A8 luxury today at the Geneva Motor The concept is powered by a 2.0 TFSI unit rated at 211 hp and 258.15 of torque combined with an motor that develops a of 45 hp and 155.63 lb-ft of torque.

The A8 has a total weight of 4,155.71 lbs and can from 0 to 60 mph in 7.6 seconds, while top is limited to 146 mph. In all-electric it can hit a top speed of 40 mph. Above 40 mph the engine alone does all the work, while the electric supplies onboard users and the battery.

The A8 hybrid is distinguished by 21 wheel rims styled highly three-dimensional surface The car is painted in Prism Silver Spectra Flair as an accent

Power like a big V6, fuel like a modest four-cylinder Audi presents the A8 hybrid as a concept at the Geneva Motor Its two propulsion units a 2.0 TFSI and an motor develop a total of 180 kW (245 hp) of system power and 480 Nm lb-ft) of torque. This the Audi A8 hybrid to accelerate in 7.6 from zero to 100 km/h mph) and to achieve a top speed of 235 (146.02 mph).

Yet its average fuel consumption to only 6.2 liters (37.94 US per 100 km the CO2 equivalent is 144 grams per km (231.75

The technology of the Audi A8 hybrid

The engine of the Audi A8 hybrid is the 2.0 a high-tech powerplant. This unit, which has been “Engine of the Year” five in a row since 2005, is an example of downsizing philosophy. It combines fuel injection with and the AVS Audi valvelift system, regulates the valve lift in two

In combination with the adjustable camshaft, the Audi valvelift improves cylinder charging and spontaneous and powerful torque The 2.0 TFSI delivers 155 kW (211 hp) and 350 Nm lb-ft); the torque value constant from 1,500 to rpm.

In the crankcase of the four-cylinder which has a displacement of 1,984 cc, two shafts offset second-order forces to ensure virtually and pleasantly quiet operation goes well with the character of the A8. All components are optimized to friction. The flow-rate-regulated, pressure-controlled oil further reduces fuel


Electric motor with propulsive power

A hydraulically wet clutch links the 2.0 TFSI the electric motor. Its control the utmost precision, and a great of know-how has been expended to its smooth, precise and swift The synchronous motor, which is excited, also serves as a that develops 33 kW (45 hp) of power and 211 Nm lb-ft) of torque. Its full is available practically right standstill and contributes to a sportily start-up. Sin ce an electric motor develops heat, its housing is with cooling ducts.

between the electric motor and the of the eight-speed tiptronic, which is entirely by electronics, is an additional clutch. In conjunction with the unit, this functions as a converter. The propulsive power of drive systems is applied to the through the front wheels.

technology the battery

The energy system of the Audi A8 hybrid is in the rear section. This lithium-ion battery is more and weighs less than types but is substantially more It is protected by a high-strength housing, and a module ensures that it operated within the ideal range. Yet the A8 hybrid also ample luggage space of 400 (14.13 cubic feet)

Several subsystems that on engine power in a conventional car been modified right the start for use in the Audi A8 hybrid. The in the climate control system entirely on electric power. The system is electromechanical as well. The booster too is supplied by a demand-controlled vacuum pump.

During i.e. recuperative braking a sophisticated control system that the ABS and ESP functions operate

The power electronics unit the interaction of the systems. Its pulse inverter regulates the interplay of the and the electric motor. The DC-DC supplies power to users on the network.

The power electronics which is connected to the battery and the motor by high-voltage cables, is in the engine compartment.

The smooth of these components and their level of integration attest to the know-how Audi has accumulated. The architecture already provides a of a future production model the Q5 hybrid, which will be later this year.

experience

The Audi A8 hybrid, which 1,885 kilograms (4,155.71 drives as if it had a big six-cylinder gasoline or a TDI under its hood. From to 100 km/h (62.14 mph) the accelerates in 7.6 seconds, and it can continue to up to 235 km/h (146.02 mph). Yet its consumption according to the EU cycle is 6.2 liters per 100 km (37.94 mpg), to 144 grams CO2/km (231.75 In city traffic, the hybrid uses about 20 percent fuel than a conventional

Both the car’s performance and its economy benefit substantially a major advantage of the A8 model its lightweight aluminum body on the Audi Space Frame (ASF).

The hybrid drive is for fully electric-powered driving up to 65 (40.39 mph) and for a distance two kilometers especially well-suited for in the city or residential suburbs. conditions permit, the driver can select the electric mode by a separate e-key in the cockpit. the display screen of the instrument and the large monitor of the MMI operating on the dashboard present all momentary flows in brilliant graphics.

the Audi A8 hybrid starts both of its engines interoperate to suit varying power Above 65 km/h (40.39 the combustion engine alone all the propulsive work, while the motor supplies onboard and recharges the battery.

When the driver lets up on the the combustion engine is disconnected the drivetrain, so the Audi A8 hybrid In braking and slow-down phases, the functions as a generator recuperating efficiently and feeding it into the

When the driver floors the the engine management temporarily the entire system power, and now the motor is boosting power. 180 kW hp) and 480 Nm (354.03 lb-ft) endow the big with enormous thrust. The sprint from 60 to 120 km/h to 74.56 mph) in fifth for instance is accomplished in 7.5 seconds. The A8 hybrid is an extremely dynamic car a fuel efficiency that is new standards. This is especially in everyday user activities.

its looks betray the power of near-production concept car with its big wheels and their 265/35 Efficiency and sportiness are no paradox at they go hand in hand.

The of the Audi A8 hybrid

This concept car has 21-inch, two-colour rims styled with three-dimensional surface areas. The paint job of the A8 hybrid is in “Prism with “Spectra Flair” as an color a rainbow effect accentuated in reflected light creases and seams on the body. The located “hybrid” lettering on front fenders leaves no about what kind of car is.

The accentuation of its width by a prominent low spoiler edge and a chrome conveys the vehicle’s solid on the road.

The engine compartment with its high-gloss finish and the cover of the battery in the trunk provide visual links to technology. And the illuminated doorsteps the “hybrid” insignia as an elegant to underscore the electric aspect the doors are opened using LED to minimize energy consumption.

The also see the prominent hybrid displayed on the dashboard. The Powermeter in shows the energy flow in the cluster.
