Mercedes CLS Shooting Brake by Brabus (2012)

Mercedes tuning specialist Brabus has unveiled a raft of packages for the new CLS Shooting Brake. A range of tune-ups, body addenda, alloy wheel designs and sports exhaust packages are to be offered, but the real headline act is the 611bhp option for the flagship CLS63 AMG variant. It's not just a mad-cap power struggle though; Brabus offers a three-year/62,000-mile warranty on all its power upgrades, so bear that in mind if the other half isn't convinced your new family estate needs McLaren 12C-chasing poke.

New (2014) Mercedes S-Class highlights on video

The new Mercedes S Class (pictured) boasts a wealth of technology The new Mercedes S Class was launched last month as a styling evolution of the current S Class, but with a wealth of new safety and technology systems lurking under its, still familiar, skin. The S Class may be portrayed as a bit of a ‘Merchant Bankers’ car, but anyone who’s lived with one for any period of time will know there’s really nothing quite like it (well, if you ignore the mistake that was the W220 S Class), and now Mercedes has got its quality Mojo back, the W221 is once again a very special S Class, and the new W222 promises to be even more special. We know that the 2014 S Class will get a range of engines from frugal 4-cylinder to potent V12 – with engines to suit all in between – but whatever engine you choose there will be a raft of technology at your fingertips (some at extra cost depending on the model you buy), so Mercedes has been busy producing a ‘Story’ video highlighting much of the new S-Class’s tech.

London's GPS-based speed-limit trial puts Big Brother's foot on the gas pedal

A fleet of 12 Toyota Priuses in London have been fitted with GPS-linked speed limiters to measure how drivers respond to having their speed controlled by a computer rather than their own feet. For now, the trial is local to London, run by Transport for London, the agency that manages the city's roads, buses, subways and trains. The agency is using its own fleet of Priuses for the test and will add a bus and a taxi later this year.
