BMW raids DTM, F1 and Formula E to create new V8

There is almost nothing like an old V8 to make a new race automobile even more interesting. The Porsche 963, for case in point, takes advantage of an evolution of the screaming 4.6 very first employed in the RS Spyder 15 years ago. Now BMW is following go well with (kind of), confirming that its new M Hybrid V8 has a combustion motor with roots in an previous DTM vehicle.

Back when DTM was applying thoroughly unique race automobiles exceptional to the sequence (and was not just a further GT3 championship), BMWโ€™s M4 DTM was working with a โ€˜P66โ€™ V8. It was a normally aspirated 4.-litre 90-degree device, creating peak electric power at 7,500rpm for 2017 and 2018 it generated additional than 500hp and was acknowledged as the P66/1 – which is the motor which is been made use of to create the M Hybridโ€™s V8.

Which is odd, since the new LMDhโ€™s motor is twin-turbocharged, and BMW already has a twin turbo V8 race engine – the P63 as found in the M8 GTE. But evidently that was far too major. The 4-cylinder engine in the later M4 DTM was dismissed on the grounds of durability. A new motor would have been far too highly-priced and time consuming to create. So P66/1 it was – retaining up?

There is plenty far more to endorse the V8 than merely remaining mild and hard, also. โ€œIt is a large plus that we had been able to make use of current materials this kind of as steel and aluminium from BMWโ€™s time in Formulation 1 for the basis of the engine, as well as for specific components โ€“ like shafts, housing and compact partsโ€ mentioned Ulrich Schulz, Head of Drivetrain Style at BMW M Motorsport. Intriguing that BMWโ€™s time in F1 can however have an affect.

Then the really hard work on the P66/3 could get started, offered it was an originally an N/A V8 that essential to be turbochargedย and operate as part of a hybrid system. A middle-floor P66/2 was built by BMW, adding the two turbos and modifying the crank, which was then thoroughly set as a result of its paces on the test bench. Only then was the P66/3 given the go ahead, with a little bit of assistance from the Method E group in receiving the electric motor built-in.

And that appears to be like the easy little bit, in truth, with the P66 requiring its injection process to be rebuilt for immediate injection, having its block and head recast and then the pair of turbos equipped. โ€œConverting the normally-aspirated P66/1 motor into a bi-turbo and then doing work with the electric drivetrain colleagues to transform it into a hybrid travel process was incredibly complexโ€ claimed Schulz, presumably underselling the challenge to some degree.

What an motor theyโ€™ve come up with, however. The 3,999cc of V8 makes approximately 640hp and 479lb ft, revving all the way to 8,200rpm. Thatโ€™s in advance of the electrical assistance way too, donโ€™t overlook. โ€œWe now truly feel that almost nothing is standing in the way of testingโ€ added Schulz.

Which is superior information, as there is really not a lot time for it. With the engine initially started out at the close of final thirty day period, the finish of July will see a rollout in Italy, with โ€˜intensiveโ€™ tests to comply with. The Daytona 24 in January is sounding much more interesting by the 7 days.
