BMW M3 CRT E90
When BMW debuted the E90 M3, most car enthusiasts raved about the glorious new V8 engine. However, they complained about the weight gain, which made the car feel less agile. BMW answered the criticism with a special, expensive and highly limited model they named the M3 CRT. The “CRT” stands for “Carbon Racing Technology” and represents the M3 Sedan with a full carbon body, seats, interior and other pieces.
Although the effort in reducing weight was extensive, the result was just 70 kilograms less than the regular model, which was a bit disappointing. However, BMW installed a 4.4-liter V8 engine from the M3 GTS with 450 HP that provided the M3 CRT with a strong performance. Since BMW only produced 67 examples in 2011, you will need around $300,000 to buy one today.
