Aston Martin V8 Vantage N420 Roadster arrives

Aston Martin Vantage N420 Roadster It was back in June that Aston Martin announced the Aston Martin V8 Vantage N420, which is the 4.7 Vantage version of the N400, but this time – as the 4.7 Vantage is quite brisk without fiddling – the Vantage N420 has to make do with the regular model’s 420bhp.

Infiniti has 'Virtually' revelead the new Infiniti M at Pebble Beach Anyway, odd launch or not, this is a big deal for Infiniti. And – for the first time – the UK and Europe will also be getting the Infiniti M, which is Infiniti’s Flagship model, aimed at the Lexus LS and – I suppose – the S Class, 7 Series and XJ, although it is slightly smaller. As we noted from the teased silhouette we saw recently, the Infiniti M seems to take a chunk of its design cues from the Infiniti Essence Coupe, which actually kicked off the Pebble Beach event a couple of days ago.
