The Mercedes-Benz E63 AMG is the pinnacle of the E-Class line-up. It features a huge engine and loads of kit, but also has a fairly large price tag. Large V8 engine AMG is Mercedes-Benz' official tuning department and its latest incarnation of the E-Class saloon and estate is impressive. The 6.3-litre V8 delivers big numbers: 517bhp, 630Nm of pulling power, 0-62mph in just 4.5 seconds and a top speed limited to 155mph. All this is served in either a roomy saloon body or an even more practical estate. Luxury interior The E-Class AMG doesn't skimp on luxury either with full leather interior as standard and a host of gadgets to keep even the most ardent of tech fans happy such as the fully electrically adjustable seats with memory function that memorises not just the seat's position but also the steering wheel and side mirrors.Also available post-facelift was the E63 AMG S, which is the ultimate E63. The 5.5-litre engine is pumped up to an output of 577bhp and 800Nm, dropping the sprint to 62mph down to 3.6 seconds for the saloon and 3.7 seconds for the estate. In European markets the E63 is available with a four-wheel drive system called 4MATIC, but unfortunately UK buyers will only be able to order these in left-hand-drive configuration. If you want your steering wheel on the right, you'll have to make do with rear-wheel drive and slightly less traction than cars such as the Audi RS 6 especially in inclement conditions. This update also ushered in a few aesthetic updates most notably a revised front end. Some of the E63 AMG's rivals offer similar performance at a cheaper price, but in terms of pace, space and comfort, the AMG is hard to beat.There's a huge amount of Mercedes-Benz E63 AMG safety equipment on offer, which means it should be one of the safest cars around. The E-Class has scored a maximum five stars for crash safety in the latest NCAP tests. It is well-specified with passive safety kit such as side impact protection, two ISOFIX fixing points on the rear seats, Neck-Pro front head restraints to reduce whiplash as well as full range of airbags including driver's knee and pelvis air bags. There are many proactive safety systems designed to help avoid an accident such as ABS with brake assist (helps generate full braking power quickly in an emergency situation), three-mode stability system that can allow some rear end drift before intervening and brake lights that flash if the brakes are hit hard to warn following drivers. Pre-Safe is an active safety system that tensions the seatbelts, closes side windows and move seats into the safest position just before an accident.There is also Attention Assist that monitors the driver and sounds an alarm if it senses the driver is falling asleep.
