Intelligent lightweight design paves the way for even higher performance: the BMW M3 CRT.

Carbon Racing Technology: BMW M GmbH factory produces a limited-edition high-performance sports car based on the BMW M3 Saloon – Innovative use of carbon-fibre reinforced plastic minimises weight – Weight-to-power ratio: 3.5 kilograms per horsepower.

Munich/Nürburg. BMW M GmbH will use the M Night event in the lead-up to the Nürburgring 24-hour race to unveil a spectacular new addition to its model range. The BMW M3 CRT (Carbon Racing Technology) embodies a concentrated blend of state-of-the-art development expertise – inspired directly by motor sport – in the areas of drive system and chassis technology and intelligent lightweight design. It also represents the worldwide debut of a new production process for carbon-fibre reinforced plastic (CFRP) components in the automotive industry. This process allows CFRP to be introduced widely in the construction of the high-performance BMW M3 Saloon-based sports car created by the BMW M GmbH factory. And that helps it achieve a weight-to-power ratio of 3.5 kilograms per horsepower. A V8 engine with customary M high-revving characteristics and maximum output of 331 kW/450 hp accelerates the BMW M3 CRT from 0 to 100 km/h in just 4.4 seconds. The BMW M3 CRT will be produced by the BMW M GmbH factory in a limited run of 67 units. Following in the tyre tracks of the BMW M3 GTS – of which 135 examples were produced – this is the second small-series, high-performance M3 off-shoot to be bred for the race track but registered for the road. The exclusive character of the Saloon is emphasised by bespoke lightweight design components manufactured as part of an innovative production process. The bonnet of the BMW M3 CRT and the bucket seats for the driver and front passenger are made from a cellular carbon honeycomb, which is produced in a globally unique process pioneered for the manufacture of body components for the BMW i3 and BMW i8 models.

Innovative manufacturing process for lightweight CFRP components.
These new models – due to enter volume production in 2013 and equipped with innovative electric and BMW ActiveHybrid drivesystem technology – will feature a body consisting entirely of CFRPin the passenger cell area. In a new development, the production process introduced for this purpose enables the cuttings left behind in the construction of the body to be reprocessed. The basic material (made up of carbon fibre thread) can now be woven into CFRP mats of any size before being impregnated with synthetic resin and hardened in a similar way to the material used in the body of the BMW i3 and BMW i8. For the BMW M3 CRT this allows the creation of a bonnet made from two CFRP mouldings encasing an aramid honeycomb structure. This construction imbues the bonnet with the
strength of a conventional steel equivalent, but at roughly a quarter of its weight. The weight saving over the aluminium bonnet of the standard BMW M3 Saloon is around 50 per cent.

The material produced through this innovative manufacturing technology is also used for the car’s bucket seats. Here, the CFRP layers are wrapped around a recycled-paper honeycomb, with a carbon layer made using conventional production technology added to visible areas. CFRP is also used to make both the rear spoiler of the BMW M3 CRT and an air-channelling element integrated into its front apron.

This innovative manufacturing process opens up considerable potential for increased use of CFRP in series-produced cars as a means of lowering weight. The BMW Group is leading the way in this area of automotive construction, while BMW M GmbH can call on extensive racing expertise when it comes to intelligent lightweight design. The BMW M3 CRT is the latest in a fine tradition of highly exclusive high-performance sports cars optimised with the help of lightweight design. This lineage stretches back to the BMW 3.0 CSL of the 1970s and reached another high point in 2002 with the BMW M3 CSL. BMW M GmbH also broke new ground with the use of CFRP in series-produced vehicles; like the BMW M6 produced up to
2010, the current BMW M3 Coupé comes as standard with a roof made from carbon-fibre reinforced plastic.

Significant weight reduction despite generous standard equipment.

The low-weight construction of the BMW M3 CRT is enhanced by sound-proofing configured specially for the new variant and a sports exhaust system with an extremely lightweight titanium muffler. Also unique to the CRT are the two individual rear seats, which take their cues from the lateral support-enhancing contours of the front seats.
Included in the standard specification of the BMW M3 CRT are the M double-clutch transmission with Drivelogic, Navigation system Professional, BMW Individual High End audio system, a light, exterior mirror and luggage area package, an alarm system and Park Distance Control with sensors at the front and rear of the car. Despite this extremely generous selection of standard kit, its DIN unladen weight of 1,580 kg undercuts that of the standard BMW M3 Saloon by around 45 kg. When you take into account the equipment on board the weight saving is more like 70 kg. Added to which, cleverly reducing the load at the front of the car raises the proportion of the car’s weight over the rear axle to 48.4 per cent, which has an extremely positive effect on agility.

High-revving V8 engine with extra power; M DCT Drivelogic.

Under the CFRP bonnet of the BMW M3 CRT lies a variant of the V8 engine developed exclusively for the BMW M3 with further increased displacement, output and maximum torque. The high-revving unit provides the linear power delivery you expect from an M car and a highly responsive performance profile honed by the demands of the race track. Tuned for the BMW M3 GTS, the eight-cylinder engine develops 331 kW/450 hp from its 4,360 cc displacement. Maximum output is reached at 8,300 rpm, and the driver will find peak torque of 440 Newton metres on tap at 3,750 rpm. Helping to give the engine its intoxicating performance is wizardry derived directly from motor sport, including a bedplate crankcase construction in a special aluminium-silicon alloy, individual throttle butterflies, a knock control system with ion current technology and a dynamically-optimised wet sump oil supply.

Transferring the engine’s power to the rear wheels is the M doubleclutch transmission with Drivelogic developed for the BMW M3. The seven-speed M DCT Drivelogic unit also works according to a principle developed in motor sport, allowing an uninterrupted flow of power through gear changes to deliver extremely dynamic acceleration. Its shift characteristics have been tuned specially for the engine powering the BMW M3 CRT. Shift paddles on the steering wheel allow the driver to change gear manually with optimum ergonomics. And a Launch Control function is on hand to generate maximum acceleration off the start line.

Special chassis construction with race-bred technology.

Expertise from race competition also makes its presence felt in the chassis technology of the BMW M3 CRT. The BMW M3 Saloon’s front and rear axle construction has been enhanced by a rigid rear axle subframe and coilover suspension whose dampers are individually adjustable in their compression and rebound. The sixpiston, fixed-calliper high-performance brakes of the BMW M3 CRT boast a low-weight compound construction. The vented brake discs measure 378 x 32 millimetres at the front axle and 380 x 28 millimetres at the rear. The new M3 variant also uses Stahlflex brake lines and model-specific comfort brake pads.

The specially tuned DSC (Dynamic Stability Control) system – including ABS and M Dynamic Mode (MDM) – responds to both the greater dynamic potential of the BMW M3 CRT and its optimised axle load distribution. Meanwhile, the 245/35 R 19 front tyres and 265/35 R 19 rears (fitted on 19-inch M light-alloy wheels in Y-spoke design) ensure the engine’s acceleration and braking power is transferred to the road with maximum impact. The electronic engine management of the BMW M3 CRT caps its top speed at 290 km/h.

The exclusive Frozen Polar Silver metallic exterior paint shade in combination with Melbourne Red metallic applications and special treatment for the BMW kidney grille also help to set the BMW M3 CRT apart from the standard M3. Inside, the Saloon comes with likewise exclusive door sill strips, door panels and trim strips in aluminium grain structure. Completing the distinctive ambience inside the high-performance Saloon are the Alcantara-covered M steering wheel, which has an M Drive button allowing the driver to call up his preferred set-up instantly, and special Sakhir Orange and Black bi-colour covers for the front and individual rear seats.

[Crazy Bimmer]

I want those seats.

[Q4P]

You have to love BMW, they are at times difficult to figure out. So they make a lightweight version by adding lightweight seats and exhaust for the M3 and still decide to fit the heavier DCT gearbox and navi...

Then they add the high end stereo with the most speakers and parking sensors and an alarm system (which are both much needed for a definitive track car) lol

[benzo23]

I could do without the whole silver and red theme...to bad they wont offer this in the US tho. Plus not to mention its only 100lbs lighter than the regular sedan? so who cares. I could save more on two recaro seats.

[signes]

Want!!! Not the greatest weight savings, but all around a great car. Perfect/unique color scheme for the E90. Kudos to BMW. If only they would sell it here...

[tha_good_life]

amazing!!!!

[the///Mthree]

Unfortunately Im pretty sure thats the car they said they wont be bringing to the U.S.

[saeedg48]

finally seats that can compare to the c63

[Kiemyster]

yo holy shit for once, they really pulled it off fucking nicely! THOSE REAR SEATS ARE SEX! holy hell! I WANT THOSE SEATS AS WELL!!!!!!!!!

but no love for usa. and no love for those front seats. Ill keep my front seats, but would love those in the rear.

[Grail05]

OMG.... WOW...

[mtla4]

Like it but navi as to go, ditto with the premium sound system. They could go gt3 rs style and remove those items, DCT as well.

[kitw]

WTB brakes. Hopefully they release them here as a BMW Performance option!

[radiantm3]

Looks like they took a page right out of Kemper's car:

What were they thinking?

[Pauldramos]

maybe some retro fit for the e92 would be nice to lighten the load. i'd like the increased torque and hp as well. C'mon BMW come up with a hp/torque increase kit for the NA V8...

[Jaypod]

Do want!

Kit? You mean engine swap?

[marwan]

could someone please tell me why they chose a sedan over a coupe for a CRT? doesn't make sense to me!

[///My5UV]

So the only lightweight parts are the hood and seats, right? Everything else seems to be appearance mods?

[flipm3]

Now this is a REAL Special Edition M3!!!

Some things I may note:

I'm not feeling those Melbourne Red accents.

I really want to hear more about those coilovers!!! Do you think they did a full rear coilover setup?

Brakes sound pretty awesome, I can't wait to hear how they perform. Exhaust looks pretty good, probably something similar to the GTS.

Interior is absolutely BAD@$$!!! Bucket seats look awesome, rear seats are awesome! I would prefer to not have the Navigation. But wow, I want to convert my interior to the CRT setup!!

Props to BMW, finally making a nice special edition for those with performance in mind. Now all we gotta do is figure out a way to get a hold of those parts, haha...

[-=Hot|Ice=-]

Now make the next gen M3 around the same weight and I'll buy one in a heartbeat.

That's much better.

[PKL]

MEH

[Grail05]

oh nevermind... i dont feel the need to want it... production to 67 units... hope 1 comes in the US... LOL
