FITTED with some of the most advanced safety features so far developed, performance specialists AMG have created a Mercedes muscle machine for the gentleman with a bad boy streak.

Costing the best part of £110,000, the S63 AMG is a two-ton limousine with supercar acceleration of 0 to 60 in 4.5 seconds.

In true AMG fashion, this version of Mercedes' flagship saloon is a blend of luxury and maximum performance.

It also marks the debut of a new V8 engine and some astonishing technology.

Blind spot warning devices and lane drift alerts have been around for a couple of years and now Mercedes has taken them to a new level by making the devices interactive.

Should a driver ignore the warning buzzers and lights and unintentionally cross a white line or start to overtake on a motorway with a vehicle bearing down from behind, then the system cuts in to move the car out of danger.

It works by linking the electronic stability controls into the blind spot and lane change sensors to gently apply the brakes to bring the car back on line.

Having tested the systems under controlled conditions both are effective and come into play at speeds ranging from less than 20mph to 125.

Coupled to other features already in use on the S-Class such as emergency sensors which apply the brakes and arm the airbags and seatbelts if a collision is unavoidable, the S63 is at the forefront of safety.

At the moment the system, which adds £2,020 to the price, is available only on the AMG but eventually Mercedes plans to make it available on other models throughout the range.

The same is true of the new 5.5-litre V8 engine which is being launched as a twin turbo in the S63.

Replacing the normally aspirated 6.2-litre V8 in the current S63 the new engine not only develops more power but is also more economical.

Average fuel economy is said to be 25 per cent better at 26.9mpg and CO2 emissions are some 30 per cent lower at 244g/km.

The S63 has a seven speed semi-automatic gearbox which not only delivers rapid fire changes either in manual or auto mode but is fitted with a stop/start function to boost economy further.

It is also a direct injection engine - the first time AMG has used such fuel efficient technology.

Compared to the current model with its 344g/km emissions and average consumption of less than 20mpg on a good day, and the improvements are significant.

Power output is 544bhp - up from 518 - yet if anything the new S63 is more refined than before.

The raucous performance of the current car is replaced with smooth but potent acceleration, although it can still roar like any finely tuned V8 should.

Possibly conscious that the latest S63 is not as brutish as some of its predecessors AMG has a performance pack available which pumps up the power to 571bhp.

It costs £7,890 but gives the S63 an awesome top speed of 186mph while shaving the 0 to 60 time down to 4.4 seconds.

As such the S63 is almost in a league of its own with Ferrari-like performance but luxurious appointments to rival a Bentley.

Yet despite the wonderful engineering there is nothing outlandish to the eye. Apart from the AMG biturbo badging and quad exhausts there is little to giveaway the might of this classy Mercedes.

It's pushing sophistication and technology to new limits in a car which will be appreciated by those who have come to expect the best from AMG.

Fuel efficiency is now at the forefront of the AMG ethos and the hand-built engine used in the S63 demonstrates how performance can be maintained while pushing economy to new levels.

As far as this heady class of vehicle is concerned what AMG has achieved with the S63 is a quantum leap.
