Well, I think this deserves the special edition name more than the many other pathetic attempts. That being said, I think it is a half-ass, confused attempt... If you're gonna make it lightweight, don't put nav or enhanced audio as standart (make it an option, like GT3 RS). I can understand the DCT, at least that has some performance benefits, but nav, really?
In anyways, 100lbs is just pathetic. Full akrapovic system and Recaro seats will give you that much... They could do better.
I'm not following what is done here to be considered special. Chineese aftermarket companies can do carbonfiber as well..
This is BMW hinting at what's to come in the future. CF seats like the Porsche Boxter Spyder would be sick!

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.

Would love an M3 EVO, in other words an M3 CRT minus Navi, Individual Soundsystem and all.
Some of you just don't see the point of this car and here is it:
You want a hard-core M3, like 911 GT3 RS? Not good as daily driver, slower than 911 GT3 RS, so you'd rather get the Porsche and a normal M3. You get the normal M3 but find it too heavy? BMW M wants to make it lighter for you, yet still keeping all the things you like, like A/C, navi, HQ soundsystem, some even asked head up display, and so on. The next M3 F32 will be lighter. > 1600 kg (EU)
If its CTR, then that is BMW stealing Ruf's designation for the Porsche's it has done.
So not only is BMW miserably failing at trying to steal/copy one of Porsche's GT3 RS color schemes, its also stealing/copying their naming designations.
Not quite, all indications are that this E90 is called the CRT - i was just pointing out that the video title has a typo that called it CTR...
those seats are pretty cool!!! why would bmw go trough all the trouble of making this car to sell only less than 70 units? I dont get it, they wont go trough the trouble of homologating a csl so they can sell it on the states,which would sell thousands and therefore give em a good amount of cash, but they go trough all the trouble of making a unique car to sell only tha amount? is not like selling this car will pay the bills of the research process and still give em plenty of cash.
btw bmw is getting more tuning oriented each time they come with editions. this car looks like a showcar from a tuning company

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
I know, such crap has no place on a CSL'esque car. I thought the weight reduction sounded tame when I read it...

All what u said makes sense but i can hardly believe that the F32 M3 is goin to by in the 1600KG range.its goin to be longer and wider than the current M3 and its goin to b close to 4000lbs. but with all that bein said,im sure its goin to b a quick car with some mods!!!
