2005 AC Schnitzer Tension Concept Pictures, Specifications, Information

Psychologically, tension means excited expectation or apprehension of a proposed event which is either particularly desired or feared. Physically, tension describes a force within a resilient body. Mechanical tension (symbol s) is the force per surface unit which acts in an imaginary section plane through a body, a fluid or a gas. TENSION is also the most important instrument of playwrights and authors for motivating the viewer and reader to watch and read further.

The applicaton of all these different definitions to a single vehicle is demonstrated by us at the IAA 2005 with the Concept Car: TENSION.

The basis for the was BMW M6, which underwent a performance upgrade. Optimising the entire engine management system and fitting an exhaust manifold system withl catalyst, sports rear silencer with tailpipe trims in "Sports Trim Design" help the TENSION achieve an incredible 406 kW / 552 HP. Even more imposing than the pure engine power is the maximum torque of 540 Nm at 6200 rpm, which pushes the driver back in the seat and catapults the TENSION to 100 km/h in just 4.5 seconds. The Vmax delimiter means that the acceleration thrust continues to 325 km/h before the speedo needle can relax.

To achieve good deceleration values, development of a braking system was essential. On the front axle this takes the uncompromising form of an 8-pot fixed caliper with slotted and vented brake disks in (Ø 374 mm) and with 36 mm thickness. On the rear axle, a 4-pot fixed caliper is used.

The wheels are also a new development: lightweight "Forged Wheel" with bi-colour finish embodies an apparent contradiction: reduction in weight with at the same time the largest possible diameters and widths.

The TENSION is fitted with wheels size 10.0J x 20" all round. The offsets of -12 on the front and -2 on the rear allow tyres of size 285/30 ZR 20 and 325/25 ZR 20.

To improve driving dynamics the TENSION has been equipped with an adjustable racing suspension. As well as lowering by 30 mm, the spring and damper rates have been clearly modified towards sporting performance. Furthermore antiroll bar kits and the specially developed strut brace in aluminium-carbon combination have been used.

The TENSION body conversion is absolutely breathtaking, and is totally dedicated to optimising the aerodynamics. A further focal point of the development was the improvement of the air supply and extraction for the power plant and braking system.

In comparison to the M6 a 50 mm wider body is the result of the complete conversion. At a glance: bonnet with power bulge, front skirt with large air intake, front wings with air outlet openings and 3 chromed ribs with integrated flashers, striking side skirts with large air shaft, rear skirt incl. unique underfloor wing construction with exchangeable diffuser, exchangeable rear wing.

The interior is a combination of developments from the AC Schnitzer range and special one-off products.

The AC Schnitzer TENSION was developed as a technology platform, which would cost around € 260,000.00. There are no plans for series production.
