Alfa Romeo 4C in action at the Goodwood Festival of Speed (video)

The Alfa Romeo 4C made its dynamic debut (pictured) at the 2013 Goodwood Festival of Speed The long awaited Alfa Romeo 4C finally made its debut in production spec at the Geneva Motor Show in March, and at the weekend the 4C made its dynamic debut at the Goodwood Festival of Speed. To make sure the 4C made as big an impact as possible at Goodwood, we’d expected Alfa to run up the hillclimb in the launch edition 4C, which gets plenty of extra goodies including a carbon fibre body kit and spoiler, but this 4C looked to be a standard model. But even though we’d like to have seen the launch edition with its extra carbon fibre goodies, the standard car gets exactly the same 1750cc 4-cylinder petrol engine with enough get up and go, 236bhp, to move the lightweight 4C (under 900kg) to 62mph in just 4.5 seconds.

Mayor warning over London cycling protests

SAFETY protests sparked by the deaths of six cyclists on the streets of the capital risk scaring people off switching from cars to bikes altogether, London mayor Boris Johnson will warn today. Mr Johnson will urge "more careful" language, suggesting pro-cycling campaigners could jeopardise the push to boost bike use by concentrating on recent fatalities when overall numbers were not up. Mr Johnson - addressing a safety summit bringing together cycle and haulage groups - will hail a £913 million investment in safety measures but urge people not to expect instant results.

Tesla Model X SUV will ONLY be available with four wheel drive

The Tesla Model X (pictured) will only be available with 4WD The Tesla Model X does promise to be a very appealing SUV, even if its main USP for business users – zero BIK – will have been scrapped by the time it arrives in the UK. When it does arrive, prices are expected to be similar to the Model S Saloon and, just as with the Model S, Tesla are planning a variety of battery capacity options and, we thought, an entry-level rear wheel drive model. But Green Car Reports, in response to a reader enquiry, has got confirmation from Tesla that they have now decided that all Model Xs will come only with the 4WD powertrain fitted.
