Mercedes' new four-cylinder diesels

By Stephen Dobie Motor Industry 11 April 2008 09:00 Mercedes has announced a new diesel engine, and it’s a win win situation – power is up, emissions are down. The environment can breathe a (small) sigh of relief while you have a bigger smile on your face. More importantly, it will form the base of Stuttgart's first diesel hybrid.

Volvo V60 Plug-in Hybrid: Production to double to cope with demand

It’s particularly appealing if you like a car with a decent turn of speed – the V60 will do 0-62mph in 6.1 seconds – like the reassurance and practicality of 4WD – the V60′s electric motor drives the back wheels – drive in to London on a regular basis – the 48g/km emissions are congestion charge free – and get taxed as BIK from your company. If all those apply – and you already appreciate the Volvo V60 is a very good car to start with – then the V60 plug-in hybrid is a bit of a no-brainer, even with a headline price of nearly £50k (which gets within £6k of an equivalent non plug-in after the taxpayer has chipped in). It seems that many buyers agree, and Volvo is being inundated with orders.

New Audi Q7 (2013) to shed weight. But no Audi Q9 planned.

The 2013 Audi Q7 will be much lighter than the current Q7 The Audi Q7 was rather late to the SUV party of the noughties, not hitting the road until 2005. That meant the Q7 had a bit of an edge when it launched, as it was newer than its competition, but it also means the Q7 is still soldiering on when its competition has already launched newer, shinier models. But Audi are working on fixing that, and fixing the biggest criticism of the Q7 in the process – its sheer weight and size.
