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.

Honda plans gasoline engine for the CR-Z

Honda is set to provide the CR-Z with an all-new four-cylinder gasoline-engine option as part of plans to broaden the compact coupe's appeal in key world markets, including North America. Currently available with just one engine option—a gasoline-electric hybrid system that mates a 1.5-liter four-cylinder engine with a brushless electric motor—the CR-Z is also earmarked to receive a turbocharged 1.6-liter four-cylinder engine currently undergoing development in Japan. The new unit, which is also planned for the Jazz, the Civic and the Accord, forms an integral part of an engine downsizing program instigated at Honda.
