2011 AC Schnitzer 99d Concept

The AC Schnitzer 99d Concept generates only 99g/km CO2 - that's less than any standard BMW vehicle available at present.

And despite this, driving pleasure is guaranteed thanks to 190 HP / 140 kW. The 99d accelerates from 0 - 100 in an electrifying 6.9 s and has a top speed of 235 km/h - a vehicle with all the sporting genes, in fact a true AC Schnitzer. And with a fuel consumption of just 3.8 litres diesel per 100 km.

So how does this Concept Car by AC Schnitzer manage to achieve such low figures? AC Schnitzer calls the combination of features Efficient Performance.

"Pleasure is the driving force!" That applies not only to the BMW engineers but also - and in particular - to the tuning specialists at AC Schnitzer.

Diesel engine and matching drive train

A diesel engine in a BMW Z4, and the most efficient currently available from BMW. It comes from the 320d EfficientDynamics. And of course now the power has been optimised by the Aachen specialists to 190 HP and 420 Nm torque (standard 320d EfficientDynamics Edition: 163 HP).

230 kg weight saving

The elegant lightweight coupé demonstrates what is technically possible today. The energy source for example is a lightweight lithium ion battery instead of the usual lead accumulator. The use of further lightweight materials such as carbon, magnesium and titanium has achieved further substantial savings in the interior equipment. So it's lighter than any current standard BMW.

Motor diesel and Powertrain

An engine diesel in a BMW Z4 and more effective for BMW. 320 D EfficientDynamics. And of course now the power is strengthened by specialists from Aachen to 190 HP and 420 Nm of torque (default 320 d EfficientDynamics Edition: 163 BHP).

 

TM mass weight reduction

less than 35 kg in parties directly connected to the wheels as wheels, tyres and brakes, led to a considerable increase agility and driving enjoyment. The latest techniques to forge aerospace materials guarantee the solidity and unbeatable economics of weight. For example, the system slowed secondary AC Schnitzer performance of lightweight 4-pot with light of retraction system and front axle brake discs front and rear, axes to make sure that the shortest braking distance.

Or type VIII of wheels of a piece of high resistance in AC Schnitzer 99 counterfeit. These weigh only 7. 9 kg of wheel and are connected to the vehicle with titanium wheel bolts. Experts say the measures to reduce the suspended mass does not have an advantage of savings up to four times the weight of the. This means that in terms of agility, AC Schnitzer 99 d feels as a vehicle through which all weighs less 335 kg.

 

Eco-special continental tyres

Continental BLUECO size 225/35 * 19 were an evolution of the concept of special in collaboration with the AC Schnitzer. These tires help to optimize the rolling resistance. Design is a refinement of contact sports accounts P 5 and allows athletes to lead its curve of stability and ZR rated more than 240 km/h.

 

Adaptation of EfficientDynamics

Behind BMW EfficientDynamics concept is a collection of smart technologies that reduce emissions and fuel consumption. BMW 320 d technologies were integrated into the AC Schnitzer 99 auto d:-stop, brake, screen of change of gear, lubricants energy recovery under coefficient of friction and aerodynamic.

Better aerodynamics

The body was lowered by 30 mm, in collaboration with the aerodynamic components carbon AC Schnitzer, reduced drag. Suspension of race AC Schnitzer with travel of residual adjustable shock absorber spring reduced to an athlete, but always comfortable level, in particular when driving at low speed.

 

 

Reduction of friction

Special ceramic wheel bearings are a decisive reduction in frictional resistance. In addition, optimized lubricants of low-friction to reduce friction. The high-performance brake system are equipped with a special system of retraction PFC, after each process of brake discs brake pads by retraction of 0.1 mm. AC Schnitzer wheels d 99 then turn much more easily.

 

Driving pleasure.

Individuality, uniqueness, lightweight construction and more than 20 years of experience in refining led to AC Schnitzer 99 (d) a vehicle that combines driving pleasure and fuel efficient: effectiveness of AC Schnitzer performance.
