Toyota conducted fix of Prius brakes but didn't notify drivers

Toyota Motor Corp., under fire from fresh quality complaints about its popular Prius hybrid, says it conducted a software fix to address reports of slipping brakes. But the world's biggest carmaker didn't notify customers at the time of the change. And it says it is still uncertain how to handle the thousands of Prius vehicles that were sold before the fix.

Renault Formula E racer (2013) at Frankfurt motor show

Formula E, the new elite racing series for electric single-seaters, has got the FIA’s backing, confirmed the major cities that will host the races, and now we've finally seen the crucial racecar. This is the Spark-Renault SRT_01E, a joint project developed between Renaultsport and Spark Racing Technology (SRT) which has just been unveiled at the 2013 Frankfurt motor show. There’s also been input from F1 legends Williams and McLaren, plus Dallara (which builds all the cars for the IndyCar series in the US).

Bugatti Veyron Grand Sport Vitesse world speed record: Video

We hoped that tease might be for something really interesting and new – perhaps the much rumoured 1600bhp Veyron or even the Galibier –  but it was simply a new world record for an open-topped production car. Impressive, of course, but just more of what we expect from Bugatti, rather than something new and innovative. The new world record for the Vitesse was set at the VW facility at Ehra-Lessien where Chinese driver Anthony Liu took the Veyron Grand Sport Vitesse to 254mph, creating a new world record for an open-topped production car and, more importantly for Bugatti, an excuse to produce a limited run of the Veyron Grand Sport Vitesse WRC Edition with a black and orange paint job for €1.99 million each.
