2014 Audi A3 e-tron Delivers Efficiency And Innovation

2014 Audi A3 e-tron which will have a premiere in Geneva has an “electrified” drivetrain thanks to a plug-in hybrid technology. With 150 kW (204 hp) of system power and 350 Nm (258.15 lb-ft) of system torque, sporty performance is guaranteed.

Further details are that the car has a top speed of 222 km/h (137.94 mph), and sprints from 0 to 100 km/h (62.14 mph) in 7.6 seconds. The five-door model consumes on average just 1.5 liters of fuel per 100 km and has CO2 emissions of 35 grams per km (56.33 g/mile).

When it operates in electric mode, the Audi A3 e-tron reaches a top speed of 130 km/h (80.78 mph) and has a maximum range of 50 km (31.07 miles). The combustion engine is a modified 1.4 TFSI that generates 110 kW (150 hp).

Moreover, a clutch links the TFSI to an electric motor with an output of 75 kW. The latter is integrated into a newly designed six-speed e-S tronic, which sends the power to the front wheels. It is important to mention that both motors work in cooperation. The electric one deliver a peak torque that starts from around 2000 rpm, and the TFSI’s maximum pulling power is available in a range from 1,750 to 4,000 rpm.

Of course, this Audi model can be driven with just the combustion engine, just the electric drive or in hybrid mode. In addition, the driver can choose to have both powerplants active at the same time (“boosting”). On the other hand when he or she lets up on the accelerator, they both deactivate temporarily (“gliding”) thus motor braking torque is eliminated and efficiency is enhanced.

Audi A3 e-Tron at the Auto Shanghai 2011

Audi is currently exhibiting A3 e-Tron Concept at the Auto Shanghai 2011. It is a four-seat sedan, which is not full electric, but features a plug-in hybrid system. A3 e-Tron Concept is based on the A3 sedan Concept, which was recently introduced at the Geneva Auto Show.

The plug-in hybrid drivetrain includes a highly-efficient 1.4 liter TFSI four-cylinder petrol engine delivering 211PS (155 kW) coupled to an electric motor with 27PS (20 kW). The total maximum power is 238PS (175 kW). All power is put on the road through 7-speed S-tronic transmission, wihch grants smooth gear-changing and perfect response.

The performance is grat – 0 to 100 km/h in 6.8 seconds and top speed of 231 km/h (144 mph). Furthermore, the A3 e-Tron features the intelligent Audi thermal management system, a start-stop system and an energy recovery system.

Audi A3 e-Tron plug-in hybrid can go only on electricity with the help of the 12 kWh lithium-ion batteries located behind the rear seats. The range is perfect for everyday driving – up to 54 km (34 miles).

The chassis is derived from the current RS3 Sportback, so it is capable of handling the power from the drive system at all times. The front suspension has a MacPherson construction with a separate axle support. The four-link rear suspension is likewise fixed to a subframe. The shock absorbers and coil springs are mounted separately from each other. The ESP stabilization system has a Sport mode and can be completely deactivated, if desired.

A3 e-Tron stands on enormous 20” light alloy wheels fitted with 245/30 ZR20 tires at the front and rear.

Audi A3 e-Tron Concept is amazing on paper, but whether it will go in production?

Audi has revealed A3 e-Tron, which is based on the Sportback version of the model.

Audi A3 e-Tron is powered by an electric motor developing 136PS (100 kW) and 270Nm (200 lb-ft). This power unit weighs around 65kg and offers 82PS (60 kW) of continuous power. All power is send to the front wheels through a single gear transmission. The acceleration is pretty good for an electric vehicle – 0 to 100 km/h in 11.2 seconds and top speed of 145 km/h (90 mph).

The electric motor receives power from a lithium-ion battery pack, which is placed in the floor of the luggage compartment and under the rear seats. The batteries weighs 300kg and can supply 26.5kWh of energy at 380 volts. Still, A3 e-Tron offers 265 liters of luggage space. The power is enough for a range up to 140 km, however, if A3 e-Tron is in dynamic mode, the range drops very fast. The other mode is Efficiency and it offers full range.

On a regular, 230V socket, the Audi A3 e-Tron requires 9 hours to fully recharge. If there is a 400V socket, the time is dropped in half.
