Porsche 911 GT3 RS

Porsche has released pictures of the most intense 997 yet, the GT3 RS. Due to be released in spring next year in North America, the RS produces 415PS from its naturally-aspirated 3.6l flat-six, enough for a 0-62mph time of 4.2 seconds. Power is sent through the rear wheels only, whose surrounding shoulders widen by 43mm to accommodate the extra track.

Lexus GS 300h: Shanghai Motor Show

Offering much better economy than the GS 450h, it offers not only a viable alternative for private buyers looking for a bit of beautifully built Japanese luxury with lower running costs, but also makes the GS a much more appealing option for company car drivers – probably where most of the sales will be made. Lexus are aiming for Co2 emissions below 110g/km for the GS 300h (the IS 300h manages 99g/km) which will give headline economy around 60mpg – a third better than the GS 450h can manage. Power comes from the same hybrid drivetrain as the IS 300h, which means a 2.5 litre petrol mated to an electric motor and delivering 215bhp and o-62mph in around 8.5 seconds.

Porsche 911 GT3 R (2010) first pictures

This is the Porsche 911 GT3 R, a hardcore racer powered by a 4.0-litre flat six and designed to compete in international FIA GT3 race series come 2010. Yes. First there was the GT3, then the more powerful and wider-bodied GT3 RS, and then a Cup race version of that car.
