Special edition M3 CRT highlights new weight-saving technology.
- Shouldn't it be called CSL?
Apparently, it couldn't, because the CSL (Coupe{aac} Sport Light) moniker belongs to the two-door M3. The four-door M3 seen here in these official pictures has been tagged CRT, meaning carbon race technology.
Apart from the regular carbon-fibre-reinforced plastic (CFRP) roof , the CRT gets that lightweight material for the bonnet and seats. BMW says these two specific components will be used in the next-generation electric and hybrid model range consisting of the i3 city car and i8 sports car, both due for release in 2013.
The CRT also employs that exotic material on the boot-mounted spoiler and front apron.
- Got it. What are the benefits?
BMW claims that the use of CFRP helps the bonnet weigh 50% less than that used in the regular M3. The CRT tips the scales at 1,580kg _ 45kg less.
To ensure that performance will differ more, BMW has slotted a 450hp 4.4-litre V8 and seven-speed dual-clutch automatic into the CRT. The normal M3 uses a 420hp 4.2-litre V8.
As a result, the CRT is faster from 0-100kph by 0.3sec at 4.4. BMW has also extended the capped top end from 250kph to 290.
- It sounds like the GTS...
Probably because the GTS and CRT share the same engine upgrade, but their approaches are slightly different.
While the CRT is a four-door road car with lightweight technology, the GTS is a stripped-out two-door with driving characteristics additionally tuned for track use.
And because the coupe{aac} version of the M3 is lighter overall in weight than the saloon, the GTS is less porky by 50kg at 1,530kg.
In spite of this advantage, the acceleration times between the two are identical, although the GTS's top speed has been raised to 305kph.
The seats (pictured at left), front apron and rear spoiler (above) are all made of carbon-fibre-reinforced plastic.
- How much does the CRT cost?
BMW hasn't announced the price yet. But given that BMW is making only 135 units of the GTS, each costing well over 15 million baht in Thailand _ including tax _ the CRT could even be dearer since only 67 will be made. Oh, and all in left-hand drive.
- Good. No right-hookers needed.
