BMW has just unveiled the M550d xDrive, and its powerplant is billed as “the world’s most powerful 6-cylinder diesel engine in the automotive area”. The M550d xDrive is the diesel counterpart of the M550i xDrive, and is available both as a Sedan and a Touring model.
BMW says, multi-stage turbocharging with four turbochargers help achieve the high output and powerful torque, whilst delivering an impressive efficiency. The 3.0 litre 6-cylinder diesel generates an impressive 400 hp and a massive 760 Nm of torque. 20 hp and 20 Nm up from the previous one. Transmission is an 8-Speed Steptronic Sport automatic, and the power is channeled to all four wheels via rear-biased xDrive all-wheel drive system.
M sports suspension comes as a standard feature. Others include Integral Active Steering, M aerodynamics package, exhaust system with M Performance specific twin tailpipe trims in dark chrome and M sports brake featuring brake calipers finished in blue metallic with M inscription.
The M550d xDrive rides on 19-inch Double Spoke light alloy wheels in Cerium Grey (front 8J × 19, rear 9J × 19) and mixed tyres in the format 245/40 at front and 275/35 at rear as standard.
