Audi e-tron models

At Audi, the term e-tron stands for cars that can cover longer distances solely on electric power. It also includes plug-in hybrids and vehicles with range extenders. By 2020, there should be an Audi e-tron model available in every vehicle class, and together they should achieve an annual volume in the six-figure range. Audi has already developed technology platforms in many segments.

The Audi A3 e-tron concept is designed as an efficient, parallel plug-in hybrid. Its 1.4 TFSI engine produces 155 kW (211 hp), the electric motor 20 kW. Both units drive the front wheels. With its capacity of 12 kWh, the lithium-ion battery provides enough energy for a range of roughly 50 kilometers (31 miles). The Audi A3 will go into production as a plug-in hybrid in 2014, with the Q7 and A4 to follow a short time later.

The parallel layout of the drive components also provides for high efficiency in the plug-in hybrids. Splitting up the power of the combustion engine and the additional electric drive unit between the axles is an interesting alternative, however.

This is the approach taken by the e-tron quattro concept based on the Audi A5. In this case, the 2.0 TFSI engine mounted in the front of the car is augmented by two powerful electric motors, one mounted at the front axle and the other at the rear axle.

The dynamic Audi e-tron Spyder is also a plug-in hybrid, but it is based on a different concept. Its primary powerplant is a three-liter TDI engine producing 221 kW (300 hp). It is mounted behind the occupant cell and drives the rear wheels. Two electric motors producing a combined 64 kW drive the front wheels.

The LMP1 prototype R18 e-tron quattro for the 24 Hours of Le Mans is similarly configured. A mid-mounted 3.7-liter V6 TDI delivers a good 275 kW (510 hp) to the rear wheels. The front wheels can be temporarily driven by 75 kW of electric power per wheel. The energy, which is recovered during braking, is provided by a fly-wheel storage system.

The compact Audi A1 e-tron, on the other hand, is a specialist for the urban jungle and is equipped with an additional range extender. Its electric motor drives the front wheels with 75 kW of peak power. Range is roughly 50 kilometers (31 miles) in electric mode. A rotary engine in the rear, which currently displaces 254 cc and produces 15 kW (20 hp) makes long-distance trips possible by recharging the 12 kWh battery.

The first A1 e-tron models are currently undergoing fleet trials in Munich. Audi hopes to gain valuable insights about the technology and the usage behavior of the customers. The compact vehicle is virtually emissions-free, both locally and globally. It is being powered during the fleet trial with renewable electricity, which Audi considers an important element of sustainable electric mobility.

On the opposite end of the spectrum from the A1 e-tron is the Audi R8 e-tron. It draws its 230 kW solely from the powerful electric motors and the large lithium-ion battery, which stores 53 kWh of energy.

The high-performance sports car, which is packed full of new technical solutions, will be the first e-tron model to hit the streets when Audi launches it as a limited production model toward the end of this year. It will demonstrate how dynamic and dramatic an electric car from Audi can be.

The Audi A2 concept technology study – the star of the 2011 International Motor Show (IAA) in Frankfurt – is another purely electric car. Based on a classic, four-seat space concept, it combines e-tron technology with ultra lightweight construction and the new ideas of Audi connect. The vehicle can be charged inductively using the Audi wireless charging system, making the charging process even easier for the customer.
