Jaguar R-S Range to grow – XKR-S Convertible, XJR & XFR-S planned

R-S will extend across the Jaguar range It’s been a while since we played the speculation game with Jaguar, so it’s due. The last punt we had after a tip-off – apart from the XF 2.2 diesel Jaguar denied when we ran the story – was that Jaguar were planning on building an XJ Supersport Diesel.

Why the BMW M4 is better than the M3 V8 (2013)

It’s no exaggeration to say that the turbocharged engine in the upcoming BMW M3 (saloon) and M4 (coupe) models is one of the most important engines ever produced by BMW’s M Division. No, it’s not the first turbo lump the performance off-shoot has built – you'll probably know we’ve already had the X5/X6M mutants plus the brilliant 1M and M5 and M6 – but it is the first turbo ever to slot in a production M3, the car that personifies BMW’s iconic performance sub brand, which itself has always been defined by high-revving, naturally aspirated engines. All of this explains why M’s engineers have cut their teeth on other engines first before plucking up the courage to develop the M3/M4 turbo while turning their backs on the outgoing E92 M3’s exceptional V8.

Piech was suggesting that VW--and only VW--could transform Fiat's perennial money-losing brand into a real moneymaker.
