After leaking all over the internet like, well, a French car, the stunning Renault Alpine 50th anniversary concept is official.

Called the Renault Alpine A 110-50, it's made to mark the 50th birthday of the Alpine Berlinette A 110. Renault says it's "dedicated to performance and driving enjoyment."

The mid-rear engined car has a body made from carbon fibre, painted in a shade of blue created to evoke the original Alpine blue.

The engine is a 3.5-litre V6 with 400bhp - and it's not just an off-the-shelf Renault unit: it's got custom pistons, connecting rods, camshafts, valve springs, a new crank case, and a carbon fibre air box.

Power is fed through a six-speed sequential gearbox, driving the rear wheels. And it has a limited-slip differential.


And with a kerb weight of just 880kg, it's undoubtedly outrageously rapid...sadly, Renault doesn't venture any figures.

Axel Breun, in charge of the Alpine's development, said: "Developing this concept car was a great adventure. It was a catalyst for creativity. We wanted to make a Berlinette that was of our time, and which boldly embodies Renault's passion for motorsport. We were guided by our hearts and emotions."

Sadly, there will be all kind of hoops to jump through before Renault can even consider producing it proper, not least convincing the suits that it'll make money.

Let's assume it'll cost somewhere close to Audi R8 territory...how many do you think will sell? Exactly.
