automotique . These latest spy shots show that Mercedes-Benz’s AMG performance automobile division is golf stroke the finishing touches to its new four93bhp twin-turbocharged 4.0-litre V8 flagship sports automobile, which is able to replace the Mercedes SLS, 9 months before it's scheduled  to be discovered at next year’s German car race.

Developed below the codename C190, the new automobile has been planned to switch the four-year-old SLS at the top of the German manufacturer’s line-up once that automobile is retired in Gregorian calendar month next year.

Mercedes SLS AMG replacement to rival Porsche 911 Turbo

The new model aims to challenge the exciting performance, lofty dynamics and everyday driving attractiveness of the most recent Porsche 911 Turbo at a worth, insiders counsel, which will be near £100,000 once GB sales begin in early 2015.

Originally tipped to receive the Shining PathC name 1st utilized by the SL coupé in 1971, the new front-engined sports automobile is currently expected to be referred to as GT, in step with extremely placed sources at Mercedes-Benz. The sources ensure the new automobile are going to be assembled on an equivalent assembly line used for the soon-to-be-discontinued SLS at AMG’s headquarters in Affalterbach, Germany.

The basis for the Mercedes-Benz GT AMG may be a preponderantly metallic element spaceframe chassis, parts of that square measure shared therewith used by the SLS. it's allied to suspension consisting of double wishbones up front and multi-links at the rear, that includes variable damping at the side of a raft of electronic driver aids. The body uses a mix of metallic element and composite panels.

The GT follows the SLS’s lead in self-praise a particular cab-back profile with an extended inquisitory bonnet and short rear deck, proportions determined by the initial Shining Path. however in a very bid to enhance usability and attractiveness to a broader cluster of prospective customers, the new Mercedes-Benz adopts standard front-hinged doors in situ of the SLS’s gullwings.

Another key modification in style is that the adoption of a liftback-style rear hatch, enabling  easier access to the bags compartment than a traditional boot. like the SLS, associate electronically controlled spoiler deploys from the rear of the boot lid to produce other downforce at speeds higher than 75mph.

Preliminary figures place length at 4500mm, that counsel that the new GT are going to be 140mm shorter than the SLS. dimension and height square measure near those of the SLS at 1939mm and 1287mm severally.  It rolls on standard-issue 19-inch wheels shod with 265/35 front and 295/30 rear tyres

The GT eschews each the naturally aspirated six.2-litre V8 engine found within the SLS and twin-turbocharged five.5-litre V8 mill that powers alternative AMG models to become the primary Mercedes-Benz to host a replacement twin-turbocharged four.0-litre standard V8.

The new engine, conjointly set to seem in a very successor to the C63 AMG, shares its design with the turbocharged a pair of.0-litre in-line four-cylinder engine utilized in the recently introduced A45 and CLA45. endued with with a 90deg cylinder bank angle, the V8 is mounted low and 
well back within the engine bay, nearly entirely behind the front shaft line for the simplest potential weight distribution.

Official output figures square measure nonetheless to be disclosed, however AMG insiders have indicated that the new engine has been tuned to deliver somewhere within the region of 493bhp, yielding a particular output of 123bhp per cubic decimetre. This pitches the GT’s output into an equivalent territory because the Porsche 911 Turbo, that generates 514bhp.

Despite gifting away over 2 litres in engine capability to the SLS, the appliance of forced induction sees the GT’s torsion reserves swell to an analogous level at 480lb foot. however whereas peak torsion for the SLS arrives at a comparatively high 4750rpm, the GT can deliver most twist below the 2000rpm mark.

These exciting reserves square measure channeled via a light-weight carbonfibre mechanical device shaft to a seven-speed dual-clutch automatic gear case mounted inside the rear shaft assembly, a layout that helps to produce the GT with a forty eight per cent front, fifty two per cent rear weight distribution. A mechanical protection differential is then wont to apportion drive between the rear wheels.

The gear case is delineate as being a development of the Getrag-produced unit utilized in the SLS. it's been upgraded to incorporate associate automatic stop-start perform for other fuel savings in town driving. Brake energy recovery is employed to spice up driveline potency, whereas new software system mapping is claimed to enhance the standard of substances changes.

With a preponderantly metallic element structure and alternative light-weight construction measures serving to to suppress curb weight to around 1550kg (which is 145kg but the SLS) the GT is claimed to yield a power-to-weight quantitative relation of near 320bhp per metric weight unit.

Straight-line performance is nonetheless to be formally certified, however Mercedes-Benz sources hint at a 0-62mph time of “well below four.0sec” and a high speed “above 190mph”. At an equivalent time, they claim the new automobile can come combined-cycle fuel consumption of “close to 30mpg”.

Mercedes-Benz’s AMG division has left no stone unturned  in its bid to produce the C190 with class-leading dynamics. The chassis, whereas sharing elements with the SLS, boasts distinctive pure mathematics. The new Mercedes-Benz 
sports automobile conjointly adopts associate electro-mechanical mechanism that’s sourced from the new C-class and replaces the hydraulic set-up utilized by 
its forerunner.

In a move that has furious rival Porsche, AMG has secured the services of Markus Hofbauer, the person attributable with a lot of of the chassis development distributed on the most recent 911. He has been charged with the task of fine-tuning the handling of the GT, that is already aforesaid to lap the Nürburgring circuit quicker than the quality SLS.
