Aston Martin Hybrid Hydrogen Rapide S race car revealed

The new Aston Martin Rapide S was revealed in January, and now Aston Martin are taking the Rapide S racing, but with a twist – it’s going to be able to run on hydrogen. Aston Martin has been working with hydrogen experts Alset Global and have developed a twin turbo version of their 6.0 litre V12 that can run on petrol, gaseous hydrogen or a blend of both and the plan is to run the Rapide S at the 24 Hours of Nürburgring next month with at least one lap run on hydrogen alone. The hydrogen system in the Rapide S (which AM are calling a hybrid, but it’s only a hybrid in the sense it uses two fuels, not that it uses electric motors) has a hydrogen fuel rail, storage tanks and its won engine management system to control combustion.

Daihatsu FC ShoCase

The FC ShoCase is the most unorthodox of the three concepts being previewed by Daihatsu prior to their unveil at the forthcoming Tokyo motoshow. The 'FC' in the name stands for fuel cell, and this concept is in essence a technology demonstrator for the company's next generation technology, which use no precious metals in their construction. Sitting – like its concept siblings – under the Kei car classification (it is just 3395mm long), the FC ShoCase nonetheless has space for four occupants, seated in exceptionally thin seats that fold down to create a secondary floor.

New Audi RS6 to get 572bhp V8

The 2013 Audi RS6 looks set to swap its V10 for the new Audi V8 with the wick turned up to 572bhp – the same as the old V10. Most of the new A6 range has now arrived in showrooms – including the S6 and Avant – but what’s still missing is a new RS6, the Audi that used to have the heart of a Lamborghini. But as we reported in April, the 2013 RS6 is well on the way but it will be losing its Lamborghini V10 with its 5.2 litres and 572bhp and will instead get the Audi/Bentley twin-turbo 4.0 litre V8.
