New McLaren F1 to debut at Monaco 2012?

Render of the 2013 McLaren F1 It’s reported that the new McLaren F1 – know as the McLaren P12 – will debut as a concept at the Monaco Grand Prix weekend in May 2012. We first revealed that a new McLaren F1 was being developed in Woking almost three years ago, but at that time it looked like the new F1 – codenamed P12 by McLaren and perhaps destined to get the McLaren 799 moniker – would arrive after both the McLaren MP4-12C and a smaller, higher-volume McLaren aimed at cars like the 911 and R8. By 2011 reports were saying that McLaren had brought forward the new F1 to 2013 and that it would get a 5.0 V8 with something around 800bhp, a carbon fibre tub (just like the 12C) and lots of electronic handling aids like brake steer and brake force distribution, ceramic brakes and a very low weight.

‘Nemesis’ breaks UK electric car speed record

An electric car – based on a second-hand Lotus Exige – has broken the UK electric car speed record with a speed of 151.6mph. We’re not entirely sure how relevant a new UK speed record for an electric car is, but let’s be parochial and report it anyway. The ‘Nemesis’ is an electric car built round a second hand Lotus Exige, bought off eBay, by a team of engineers in a shed in Norfolk and driven by an Estate Agent from Gloucestershire.

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.
