BMW has developed a 3.0 litre, quad-turbo, six-cylinder diesel rig, which the company unveiled at the Vienna Motor Symposium 2016.
It will replace the existing six-cylinder tri-turbocharged rig. The motor which is based on the 6-cylinder B57 diesel engine will come in the BMW 750d xDrive initially which will propel the car from zero to go in just 4.5 seconds, hitting a top speed of around 250 Km/ph. The engine is equipped with 4 turbochargers, out of which two are high pressure units while the other two handle low-pressure. The engine churns out a maximun power of 394 horses and a peak torque of 760 NM, which is an extra of 13 bhp and 20 NM torque over its predecessor. The engine will be coupled with an 8 sped gearbox.
The new engine performs better, has a high power-out and lower costs. This BMW claims is due the the two low pressure units which have replaced the single larger unit. The engine can also produce a torque, higher than the claimed 760NM but the gearbox can't bear it.
The 3.0 litre, quad-turbo, six-cylinder diesel rig, which is 5% more efficient than its predecessor, will first be introduction in BMW 750d xDrive followed by the M performance verions of X5 and X6
