British Motor Show - Mercedes' green drive and SLR
At the other extreme, the manufacturer has three Smart Eds dotted around the halls.
The zero-emission electric vehicles aren't on sale yet, but are currently on test with leasing customers around the UK as part of a series of trials.
Powered solely by electricity, and chargeable from any three-pin socket, the Smart Ed can achieve the equivalent of 300mpg - that amounts to a saving of up to 80% in fuel costs over the Smart Fortwo.
It can travel up to 72 miles between charges, which typically take around eight hours for a full charge.
There's also a CLS 350 Blue Efficiency, which goes on sale this autumn and showcases some of the technology that's being wheeled out across the Mercedes range as it attempts to reduce emissions.
If you're more interested in cars you can buy now, there's something to suit every budget, from the A-Class through to the Maybach 67.
