What is it?
As much as hybrids and pure-electric cars are flavour of the moment, Audi plainly believes that there is a whole lot more efficiency to be squeezed out of the internal combustion engine. That point really was driven home at the launch of the eighth-generation Audi A4 range.
What’s it like?
Starting with the cosmetic changes, right across the Audi A4's model line-up there have been mild cosmetic tweaks to the nose and tail, with subtly modified bumpers and air intakes. The front and rear LED running lights also get a classier look, too. It’s not a major revamp though – there are no sheet metal changes to the range. LIkewise, the A4's interior gains a mild colour and trim tweak.
Mechanically, the most significant changes focus on the turbo-diesel engine lineup. There are six offerings, with an entry-level 134bhp four-cylinder rising up through the range to a 242bhp V6. And without any dramatic engineering solutions – efficiency has come so far in recent years that pretty much all gains will be incremental now – Audi has managed to make significant improvements.
