Infiniti revealed a new version of the Q50 Eau Rouge concept at the Geneva Motor Show. This one has one big difference with the one we saw before: it has an engine! And what an engine it is – a twin-turbocharged, 3.8-litre V6 petrol engine out of the Nissan GT-R.

The engine is tuned to make 568hp and 600Nm of torque in the Infiniti Q50 Eau Rouge, and it boasts a soundtrack a lot sweeter than that of the big Nissan. The engine is mated to a 7-speed automatic transmission and all-wheel drive system with 50/50 front-to-rear torque split.

All that means the Eau Rouge is quite a performer, with predicted acceleration of 0-60mph in less than four seconds and a top speed close to 180mph. The concept also features a massive carbon fiber body kit with large air intakes and flared arches, as well as a race car-inspired interior.

“Building on the extremely positive feedback on the Q50 Eau Rouge at its recent Detroit Auto Show launch, we decided to further whet the appetite of performance sports saloon fans by engineering this powerful heart into our blood-red beast,” said Johan de Nysschen, President of Infiniti Motor Company Limited.
