What does a costly aerodynamic conversion look like without the right wheel and tyre combination? We think it's incomplete. So we decided to equip the TENSION Street Version with the latest AC Schnitzer wheel generation: the forged alloy Type V.

Appearance is one thing, but much more important in this context is the safety aspect. To take this into account, and secondly to meet the high technical demands placed on the AC Schnitzer Tuning wheel by our engineers, a complete new wheel development was required.

The result is the Type V alloy forged wheel with bi-colour finish. It has a partly polished, partly painted surface. This wheel type, available for all 5 and 6-series, achieves a fundamental paradox: reduction in weight with simultaneously maximum wheel diameter and width. The TENSION Street Version is fitted with rims size 9.0J x 20" on the front and 10.0J x 20" on the rear, and each front wheel weighs in at just approx. 10.8 kg. The tyres to fit the wheels are size 245/35 ZR 20 on the front and 285/30 ZR 20 on the rear.

In conjunction with the wheel and tyre combination, a sports suspension has been developed for the TENSION Street Version which lowers the vehicle by around 25 - 30 mm and perceptibly improves driving dynamics. For the M6, a suspension spring kit is available.

To counter lateral roll, AC Schnitzer Tuning antiroll bar sets are fitted to the front and rear axles. Another suspension highlight is our in-house spring strut brace of aluminium which superbly prevents distortion in the vehicle front.

Depending on base vehicle, the TENSION Street Version can be fitted optionally with the new AC Schnitzer 5.1 l engine. This is available in principle for all BMW 6-series with N62 B44 or N62 B48 TU engines.

The new engine offers a true alternative to the BMW M6. As this conversion is also available for vehicles with automatic transmission, fans of automatics can now enjoy the higher power in conjunction with the pleasures of an automatic.

Whereas the basic engine gives maximum torques of 450 or 490 Nm, the AC Schnitzer 5.1 l engine achieves 550 Nm. Naturally the performance has been optimised. It rises from 245 kW (333 HP) or 270 kW (367 HP) to a superb 302 kW (411 HP). At the same time, driving performance is enhanced. The top speed rises on average by around 35 km/h.

These excellent figures are obtained by the use of specially developed engine components. Individually, these are:

AC Schnitzer Tuning special cylinder block
AC Schnitzer Tuning special cylinder head
AC Schnitzer Tuning special pistons
AC Schnitzer Tuning special conrods
AC Schnitzer Tuning special crankshaft
AC Schnitzer Tuning exhaust manifold
AC Schnitzer Tuning special catalyst
AC Schnitzer Tuning Control Unit Program
AC Schnitzer Tuning sports rear silencer with chromed Sports Trim tailpipes

To achieve excellent deceleration figures, the AC Schnitzer Tuning high performance brake system from the TENSION has been modified. At the front axle, an 8-pot fixed caliper with perforated, vented brake discs and special pads ensures braking with ruthless efficiency. However, this kit is reserved for the Street Versions based on BMW M6.

Only the interior remains, and this too has been modified in typical AC Schnitzer Tuning fashion.
