First drive: A1 e-tron a revolution too far?

Up in the The Audi A1 e-tron remains for production, despite having in concept form almost two ago.

Audi s rotary extender an interesting but noisy into future EV options

21 2011

THE evolution of the Audi A1 continues with our first drive of the A1 e-tron electric car range-extender rotary engine.

on from last week s of a trial of 20 cars by selected and utility companies in Germany, the drive in Japan is the second in Audi s quest to collect analysis and data in its plans for mobility.

Debuting more 18 months ago at the 2010 Geneva show, the A1 e-tron is a Range , with its front wheels solely by an electric motor for up to before a unique rotary combustion petrol engine to the battery pack (and not the fires up at constant revs to the 270-volt lithium-ion batteries, about another 200km of

A plug-in outlet is cleverly behind the grille badge, charging times rated at eight hours.

It s an elegant and solution though one that requires much development if levels are going to match the A1 1.2TFSI that Audi had on hand in Japan as a point of

We drove a course of just along a gentle and ultra incline with a couple of for corners and a nervous Audi passenger to help with and operation instructions.

Nevertheless, the A1 s positive points are obvious the you poke the starter button.

Except for a couple of clicks and a audible electrical hum, it is an quiet way to start a car.

In case, with sufficient the electric motor is all that you hear, so Audi tells us to the latter for our short EV taster.

As with most EVs, it is the of noise, combined with a shove forward, that initial acceleration, making the car faster than the outputs and its time for the 0-100km/h sprint suggest.

Before we reach the 5km mark, a noise kicks in from behind the back seat, like a jet-plane in cruise It is the engine and it is quite noticeable and a little too loud for a premium like the A1.

A single-rotor engine a capacity of just 254cc, it at a constant 5000rpm ( the optimal point ), providing 15kW of to the 22kWh lithium-ion batteries.

says the range-extender rotary operates at a lower (though efficient) setting of about for topping-up the battery pack urgently when the car is cruising

Whichever way, hopes of the uplifting zing of a Mazda singing its way up the rev range were dashed, not least because of the CVT-like drone from the engine.

At least the rotary range-extender is not to break the fuel budget. consumption is 1.9 litres per 100km, carbon dioxide emissions at 45 grams per kilometre, according to the new NEDC system.

Interestingly, the Volvo V60 PHEV hybrid the same figure.

Audi that figure is calculated the entire distance travelled a set course that includes driving periods. Calculated a similar method, General claims the considerably larger Volt can achieve 1.2L/100km.

for the quiet turbine performance the rotary din commences, there isn t that differs from the A1.

The electro-hydraulic power steering much the same, the brakes the e-tron up with the usual and the suspension on the ultra-smooth surface did its job although most of this s vehicles behave similarly the going gets rough.

Audi said a lower of gravity and better weight as a result of the 65kg range-extender out back, improve the dynamics

The e-tron is apparently in the region of 150kg heavier than a A1.

Just 11km in super-controlled did not really reveal much but it is clear that, while the A1 looks production ready, is still much work to be in the areas of noise suppression, at the least.

Even almost two on from its debut, senior officials again declined to confirm plans for A1 e-tron let alone divulge a possible date.

Speculation suggests the may wait until the next-generation A1 along before releasing range-extender technology if at all.

So, while this car s future is very much up in the air, at it shows that Audi is a range of interesting and viable

The A1 evolution as opposed to a rotary continues.
