The Audi e-tron family is a series of electric
and hybrid
concept car
s shown by Audi
from 2009 onwards.
It has been speculated that the second e-tron concept car, shown in 2010 in Detroit, provides a preview of a future mid-engined Audi sports car
production model to be launched in 2012, possibly to be named Audi R4 or Audi R5, which may be available in both electric and internal combustion engine
-powered variants.
The name “e-tron” has been seen in the French-speaking press as laughingly close to the French word “étron” (turd).
In concept form, the e-tron also is equipped with conceptual technology: technology that communicates with other cars, road signs, etc.
. Together, these produce 230 kW and 4500 N·m (3,319 ft·lbf) of torque, resulting in an acceleration of 0 to 100 km/h (62 mph) in 4.8 seconds.
A 470 kg (1,036 lb) lithium-ion battery is located in front of the rear axle and provides a range of approximately 248 km (154 mi), with a full charge taking 6-8 hours from a normal household socket. The ceramic brake discs can also provide regenerative braking energy. A limited production model based on this car, called the R8 e-tron is reported to be under development.
in Detroit. Smaller than the Frankfurt car, this model had only two motors, powering the rear wheels. Power output is quoted at 150 kW and 2650 N·m (1,955 ft·lbf), with acceleration from 0 to 100 km/h (62 mph) in 5.9 seconds. A similar production model, based on a future mid-engined automotive platform codenamed 9X1, shared with Porsche
and Volkswagen
, is reportedly under development.
variant of the Audi A1 production model, was first shown at the 2010 Geneva Motor Show. The A1 e-tron is a series plug-in hybrid, powered by an electric motor
with a continuous output of 45 kW, and a peak output of 75 kW. A 254 cc Wankel engine
is also used to power a 15 kW range-extending generator

, this roadster
is a plug-in hybrid powered by a 221 kW twin-turbo TDI 3.0 L V6 diesel engine
driving the rear wheels, plus two electric motors together producing 64 kW powering the front wheels. Acceleration to 100 km/h (62 mph) is achieved in 4.4 seconds.
Audi presented the e-tron Spyder in January 2011 at the Las Vegas Consumer Electronics Show
, near identical to the Paris show car, but this time painted bright red. The car was advertised with the same performance specifications, including an electronically limited top speed of 155 mph (249.4 km/h).

e-tron performance
As this car is still in concept, much of its performance specifications is still uncertain. The car will have four electric motors, one per wheel. Together, these motors will produce ~3,320 pound-feet of torque. Top speed for the e-tron is limited to 124 miles per hour, and will be able to travel 150 miles on full charge.In concept form, the e-tron also is equipped with conceptual technology: technology that communicates with other cars, road signs, etc.
