BMW reveals rarest M3 yet
BMW’s released images and details of what could be the last incarnation of its V8 M3.
Affixed by the acronym CRT (composite racing technology), this latest M3 derivative is not quite a hardcore lightweight revival mimicking the legendary E46 M3 CSL but rather a showcase for BMW’s newfangled skill in fabricating composite components.
Although the M3 CRT looks no different in proportion to its M3 brethren the car’s bootlid spoiler, splitter, bonnet and front bumper are crafted from carbon-fibre reinforced plastic (CFRP) and finished in a contrasting blend of composite weave with red piping.
These new CFRP components are not simple aftermarket supplier sourced parts, either. They have an intricate honeycomb finish and special resin-hardening process to show off BMW's future composite material technology, crucial to the brand's plans for future lightweight electric vehicles.
Not only do the M3 CRT's styling add-ons look fantastic, especially the rear spoiler, but they're a quarter lighter than similarly dimensioned steel parts and have the same strength and torsional rigidity.
Beyond the newfangled composite bits, this new M3 has a custom-crafted titanium exhaust system, too. All tallied, the CRT sedan is notably lighter than a standard M3 at a kerb weight of only 1580kg (in seven-speed DCT trim); a reduction of 70kg.
NO CSL, BUT MOST EXCLUSIVE M3?
