Endless driving pleasure with only 99 g CO2 emissions

The AC Schnitzer 99d is our definition of Efficient Performance



The AC Schnitzer 99d 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.



Secret 1: 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 Edition. 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).



Secret 2: 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.



Secret 3: Weight reduction in unsprung mass

35 kg less weight in the parts directly connected to the wheels, such as wheels, tyres and brakes,

leads to a perceptible gain in agility and driving pleasure. The latest forging techniques using

materials from the aerospace industry guarantee strength and an unbeatable weight saving.

For example, the AC Schnitzer lightweight 4-pot high performance brake system with retraction

system for the front axle, and the lightweight brake discs on the front and rear axles, ensure the

shortest braking distances.

Or the Type VIII one-piece high-strength forged rims used on the AC Schnitzer 99d. These weigh

in at just 7.9 kg per wheel and are connected to the vehicle with titanium wheel bolts. Experts say

that measures to reduce the unsprung mass have a benefit of up to four times the weight saving.

This means that in terms of agility, the AC Schnitzer 99d feels like a vehicle which overall weighs

335 kg less.



Secret 4: Special Eco-tyres from Continental

The Continental BLUECO tyres size 225/35*19 were a special concept development in

conjunction with AC Schnitzer. These tyres help optimise the rolling resistance. The design is a

refinement of the Conti Sport Contact 5P, and allows sporting driving thanks to its high cornering

stability and ZR speed rating of over 240 km/h.



Secret 5: Adaptation of EfficientDynamics

Behind the BMW EfficientDynamics concept lies a technology package of intelligent measures

which significantly reduce fuel consumption and emissions. These technologies from the BMW

320d were integrated into the AC Schnitzer 99d: Automatic start-stop, brake energy recuperation,

gear shift display, low-friction lubricants and active aerodynamics.



Secret 6: Improved aerodynamics

The bodywork lowered by 30 mm, in conjunction with several AC Schnitzer carbon aerodynamic

components, reduces drag. The AC Schnitzer racing suspension with adjustable dampers

reduces the residual spring travel to a sporting but still comfortable level, especially when driving

at low speeds.



Secret 7: Reduced friction

Special ceramic wheel bearings achieve a decisive reduction in friction resistance. In addition,

optimised low-friction lubricants minimise friction. The high performance brake system is fitted

with a special PFC Retraction System which, after each brake process, retracts the brake pads by

0.1 mm from the brake discs. The wheels of the AC Schnitzer 99d then turn much more easily.



Secret 8: Driving pleasure

Individuality, exclusivity, ultramodern lightweight construction and over 20 years of experience in

refinement have led in the AC Schnitzer 99d to a vehicle which perfectly combines efficient fuel

consumption and driving pleasure: Efficient Performance by AC Schnitzer.

Naturally all safety elements are retained such as ABS, airbags and ESP. The multimedia world

too is not lacking thanks to the Apple iPhone4 integrated into the vehicle. This gives access to all

data from the on-board computer. So the actual fuel consumption, or for example the function of

the particle filter can be checked. Music, telephone, navigation, handsfree or internet complete the

overall experience in the AC Schnitzer 99d.

With the new BMW 5-series saloon and the new BMW 5-series Touring, in 2011 two new 5-seriesmodels have been awarded the prestigious iF Award for outstanding product design. Equallyprizeworthy is the AC Schnitzer ACS5 Sport S Saloon based on the BMW 5-series saloon,which celebrates its premiere at the Geneva Motor Show from 3rd to 13th March.With this concept vehicle, the Aachen-based tuning specialist AC Schnitzer is demonstratingnew and unusual aspects of driving pleasure. With a performance upgrade from 407 to 540 HP,the AC Schnitzer engineers are pushing the boundaries of the possible - for greater dynamics andefficiency. The driving performance is at thoroughbred sportscar level: the sprint from 0 - 100 kphtakes just 4.5 seconds, and the top speed is around 320 kph. A glance under the bonnet with theAC Schnitzer engine and engine bay styling shows just who is responsible for the revolutionaryrefinement. The AC Schnitzer limited slip differential with up to 75% effect ensures that thetremendous power reaches the point where it is needed.The AC Schnitzer twin sports rearsilencer with chromed "Sports Trim" tail pipe trims left and right combines exciting appearanceand sound.What does the sophisticated driver expect from perfect brakes? Perfect braking of course! Withthe AC Schnitzer high performance brake system with 8-piston fixed calipers left and right, andan 8-piece kit of brake pads and caliper holders for the front axle, all expectations of optimumdeceleration and maximum stability are amply fulfilled. And the driving dynamics leave nothing tobe desired. The AC Schnitzer racing suspension guides the saloon perfectly through the corners.The AC Schnitzer tuning specialists will be focussing on the reactions to the new aerodynamiccomponents for the body of the 5-series saloon. As well as the familiar AC Schnitzer front spoilerand chromed front grille, a new carbon front spoiler centre part gives the ACS5 Sport S Saloonan even more striking aspect. The carbon air ducts for the brakes left and right ensure adequateventilation for the high performance brake system, and the new AC Schnitzer carbon side skirtsclearly enhance the side view of the concept vehicle. The engine bay is ventilated by the bonnetvents from the current AC Schnitzer range. Together with further accessories already available,such as the AC Schnitzer rear roof spoiler, the rear spoiler and the rear skirt extension, newelements such as the AC Schnitzer sports wings left and right with Chromline Set and the carbonrear diffusor contribute to the great appearance. The AC Schnitzer loading sill protection filmand the BiColor film trim harmoniously complete the sporting elegance of the body conversion.Possible and probable reactions to such a well-equipped vehicle are envious glances, which theproud driver seated behind the AC Schnitzer sports airbag steering wheel with painted spokescan enjoy in the new AC Schnitzer sports mirror.The AC Schnitzer ACS5 Sport S saloon appears at the Geneva Motor Show with full leather trimin BiColor, painted interior trim strips and racing bucket seats with AC Schnitzer logo, whichform part of the overall concept for the interior. The AC Schnitzer range already contains theAC Schnitzer "Black Line" aluminium cover for the i-Drive system controller, the aluminium footrests and pedal set, velours boot mat and foot mats.For the BMW 5-series saloon, AC Schnitzer also provides an unusual range of custom wheel/tyrecombinations in both 20 and 21 inch diameter. The largest variants are the racing forged rim inBiColor and the new forged alloy wheel in BiColor in sizes 9Jx21" front and 10Jx21". Alternativesare the AC Schnitzer Type IV BiColor wheel and Type V BiColor forged alloy rim.The AC Schnitzer ACS5 Sport S Saloon - an extraordinary concept vehicle which embodies thestate of the art of technical achievement in more than just power. The AC Schnitzer definitionof "Performance" will certainly inspire BMW tuning fans throughout the world.
