Audi A5 e-tron quattro concept review

Audi

What — Audi A5 e-tron quattro concept

Where — Audi secret test facility, Sweden

Date — March 2011

Summary — The A5 2.0-TFSI e-tron quattro is still only at the concept stage but Audi are so excited with this hybrid they are talking about it actually going into production. We got an exclusive first drive and as you’ll read, the idea is so simple it makes you wonder why no one thought of it sooner.

By using an existing A5 as a donor vehicle for this project there are few surprises within the cabin. It remains that calm and well-laid-out place we’ve become accustomed to expect from Audi.

There are a few additional big red buttons which we were told not to touch as they are the master off/on switches for the two electric motors and the electromechanical rear brakes.

The multimedia infotainment system has also now been rewired to give a primary function as a readout monitor for the onboard computers. It shows which mode of power is being used, where the power is being sent and an LED display giving a precise state of energy remaining within the batteries’ cells.

Of course, if this car ever comes to market these conceptional extras would be integrated within the interior or hidden away in the software of the engine management system.

Economy and safety

Whenever a car brakes, or accelerates, or suffers from any type of motion there is a build-up of energy which is known as kinetic energy. What Audi has done is to harness as much of this energy as possible and turn it back into electricity to feed the batteries.

This means the A5 e-tron can drive on electric power alone for around 30 miles, but this does cut the top speed to 62mph. The batteries are also recharged by the petrol engine, which is managed by an onboard computer, or can be topped up from a household plug. The batteries take around two hours to fully recharge.

But perhaps more impressive are Audi’s claimed efficiency figures. Thanks to the hybrid powertrain, the A5 hybrid will return 104mpg while only emitting just 64g/km of C02 emissions.

The MSN Cars verdict


This may only be a concept, and it is still early on in its development, but it does show where Audi are going with their hybrid programme.

As much as they want to produce a car which offers the best of both worlds — electric and petrol — they also want to give the driver a car which can be enjoyed for more than its ability to wave an eco banner.

And if we are to believe Audi — and we have no reason not to — then we can expect to see the A5 e-tron go into full production within the next two years.
