Audi is to launch an A4-based coupé in 2007, according to a story in Autocar this week. The range-topping A5, Audi's answer to the M3, will get Audi's 4.2-litre 420bhp V8 and four-wheel drive -- it's effectively a replacement for the quattro. The concept was wheeled out in 2003 at the Geneva Motor Show (see link below for pics).
The car will be of unitary construction, made of steel and use mechanical elements from the A4 and larger A6. A full four seats are planned -- it's not a 2+2 -- and it'll be practical, with 400 litres of luggage space. As a comparison, the current Porsche 911 has a luggage volume of 130 litres.
Engines available will include 150bhp naturally aspirated and 197bhp turbocharged 2.-0-litre powerplants, both four-pot motors, plus a 255bhp 3.2-litre V6. There'll be a brace of diesels too. The range-topper will be the RS5.
