Subaru BRZ STI teased

Subaru are teasing the BRZ STI (pictured) The Subaru BRZ – the Subaru take on the Toyota GT86 – has the potential to be a lot more hardcore than its current setup allows. That has led to much speculation that Subaru will bolt a turbo on to the BRZ’s Boxer engine to produce a BRZ with something closer to the 300bhp we originally expected. In fact, at the end of 2011, Subaru in the US confirmed there would be a turbo version of the engine in the BRZ, although they fell short of actually confirming the BRZ itself would get it as an option, but at the end of 2012 we had a report that the BRZ will get the turbo engine and that it will deliver 280bhp.

Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show. It's an A7 Sportback given the hardcore RS treatment, meaning a 552bhp and 516lb ft 4.0-litre bi-turbo V8 that will sprint the RS7 to 62mph in 3.9sec. That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.

Rushed urban speed limit reductions criticised

ANY RUSH towards blanket 20mph zones on urban roads needs to be slowed down, according to a survey of nearly 25,000 motorists. Almost 70% of drivers think people should be consulted before 20mph limits are imposed on their street, the AA/Populus survey showed. More than half (55%) of the 24,351 AA members in the survey said drivers' views should be sought if 20mph zones are introduced in local areas through which they travel.
