BMW M5 – A Diesel Engine Marvel

The new BMW M5 is one stylish car that is upholding BMW’s Motorsports specialties. Extended side-sills and boot-lid spoilers are simple. BMW’s trademark quad exhaust pipes are poking out under the rear valance. Ten radiators are fed by wider and larger air-ducts at the front. As we come to the engine bay, it has a 4.4-litre, 90 degree V8 all-aluminum BMW diesel engine fed by 2 twin-scroll Honeywell turbo-chargers placed between cylinder banks. At up-to 200 bars of pressure the engine runs direct injection, as well as double variable cam-shaft timing and valvetronic variable valve lift.

BMW claims this M5 has the finest throttle response and high revolution fireworks that generate 552 bhp between the rpm of 6000 and 7000. It can rev up to a maximum of 7200 producing 10 percent more power than the outgoing V-10. This new BMW V8 diesel engine produces 502 lb ft of torque between 1500 to 5750 rpm that is 30 percent more than car it has replaced and is accessible over a three times wider band of revolutions. As compared to the old V-10, it has 30 percent higher fuel efficiency and fed from an 80-litre fuel tank which should contribute to the improvement in te cruising range by 50 percent.

The BMW M5 returns 28mpg of fuel economy, which means more than 300 miles in a tank. It does 0-60 mph sprint in just 4.4 seconds and 0 – 100mph in 9.0 seconds. The CO2 emissions are at 232 g/km and the top speed is 155 mph. The interesting fact about this 5-series’ active chassis systems – that have been developed by BMW M especially for this car – is that there is no rear wheel steer, no variable-ratio electro-mechanical power steering system, no active anti-roll bars and a very little of the gadgetry. As an alternative, the M5 is using simple, light, robust suspension and an electro-hydraulic power steering. It’s made up of double wish-bones at front and multi-links at the rear like any other car.

There are new forged aluminum chassis members, adaptive dampers, wider front track and progressive rate springs. The new car weighs 1975 kg with full fuel tank. The standard 5 Series is now much more effective and fun to drive. This new M5 Express offers a generous head and leg room, adaptive bi-xenon headlights, soft extended merino leather, a DAB radio, BMW Professional satellite navigation and head-up display. The interior is absolutely outclass, and the driving experience is delightful. It is no-doubt a marvel in diesel technology by BMW which will cost only £71,470.
