The tuning shop MKB now offers a very powerful and expensive swap package for your Mercedes GL SUV. If you can wait six months and have around $294,000, you can replace your factory V8 with a twin-turbo V12. The engine is probably from the Mercedes CL65 and is pushing 658 horsepower and 885 lb-ft of torque when tuned by MKB.
