Alfa Romeo 4C Spider revealed: Geneva Motor Show

The Alfa Romeo 4C Spider (pictured) revealed in Geneva The Alfa Romeo 4C is the epitome of a modern ‘supercar’, with ultra light weight (for a production car) allowing the 4C to produce very good performance from its modest 17500cc engine. So producing an Spider convertible immediately raises the weight issue in a more dramatic way when the car’s abilities are so dependent on it low weight, but it seems the Alfa Romeo 4C Spider – previewed as a production car with a concept at Geneva today – has managed to keep the wight penalties of the convertible 4C down to a minimum. Thanks to a canvas roof and carbon fibre rollover bars, the weight penalty for the Spider is only about 60kg (around a 7 per cent gain) which shouldn’t hurt performance too much.

New Routemaster bus hits London streets

The very first new Routemaster hybrid bus began its first day of service in London today. The bus, whose exterior and interior were designed by Londoner Thomas Heatherwick, retains the distinct character of the old Routemaster – British as the London taxi and red telephone boxes – but is far more modern in its design and construction. The new Routemaster's main design features are its three sets of doors and two staircases, which it is hoped will ease the strain during rush hour in regards to alighting and entering the bus.
