Geneva show: Audi plugs in the A3
BY MIKE COSTELLO | 22nd Feb 2013
As with the German company’s previous electrified models, the plug-in A3 is receives the e-tron moniker.
It combines sharp acceleration – zero to 100km/h is dealt with in 7.6 seconds – with fuel consumption of just 1.5 litres per 100km (and carbon dioxide emissions of 35 grams per 100km).
The e-tron will form part of a green vehicle assault from the Volkswagen Group at Geneva, with the company that owns Audi planning to show its own production XL1 EV and e-Golf concept.
The A3 joins the smaller A1 plug-in, now in its second iteration and undergoing German government-funded trials. Production has not been confirmed, but Audi certainly sounds positive about the technology.
“The Audi A3 e-tron will provide a realistic glimpse into the future of mobility as Audi is planning it,” the company said in a statement.
“The electrification of the drivetrain, above all using plug-in technology, plays a deciding role in the strategy of the brand.”As reported in January, the Ingolstadt marque axed plans to produce electrified versions of the A2 hatchback and R8 supercar (also called e-tron) over concerns that customers were not ready to accept the limited range of pure electric cars.
Plug-in hybrids that give drivers the reassurance of a backup power source are seen as a viable solution.
The A3 e-tron’s running gear consists of a 110kW 1.4-litre turbo petrol engine linked to a 75kW disc shaped electric motor via a special clutch. Power is sent to the front wheels via a newly designed six-speed ‘e’ S tronic dual-clutch automatic transmission.
Total system output is 150kW of power and 350Nm of torque – nigh on hot hatch figures – while Audi claims the two power sources “complement” each other.
Essentially, the motor provides peak torque from start-up through to 2000rpm, by which time the petrol engine’s peak torque has come on stream (at 1750rpm), before continuing all the way through to 4000rpm.
The e-tron can be driven with just the petrol engine, as a pure electric or as a combination of both.
When the driver lets up on the throttle, both sources de-activate temporarily.
