A big change for Speedsource in TUSC. They will be dumping the SkyActiv Diesel for the Mazda badged AER engine.

Mazda is poised to make a switch of powerplants this year, with IMSA having approved the use of a gasoline engine for its SKYACTIV prototype.

A technical bulletin released Friday from the sanctioning body confirms that the Lola-based prototype is now eligible to run with an AER-powered 2.0-liter turbo gasoline engine.

It’s understood to be the same Mazda-badged engine previously used by Dyson Racing in American Le Mans Series competition.

SpeedSource has campaigned the 2.2-liter SKYACTIV-D clean diesel powerplant since the Prototype program’s debut in the TUDOR United SportsCar Championship last year, although having recently scaled back to a single-car entry at Detroit to focus on further developments.

Sportscar365 first heard of the possible engine shakeup from industry sources in May, although Mazda has yet to officially comment on the likely switch.

Mazda Motorsports Director John Doonan, however, previously told Sportscar365 that different engine options were under evaluation.

“We’re having major strategy discussions about right now,” Doonan told Sportscar365 in April. “Diesels are going to be relevant for a couple more years but what can we do? Can we develop a bespoke motor?

“You [can] start with a road car engine, which is our story. That’s a difficult path, as we’ve proven here, but it also helps us find the limits of those components.

“Years ago, we developed a bespoke engine with AER and ran it from ’07 until 2012. There’s that existing motor. Do we work with a new partner? We’re in the midst of looking at all kinds of options.”

It’s unclear if both cars could debut the gasoline powerplant by as early as next weekend’s Sahlen’s Six Hours of The Glen, although at least one is likely.

Two cars are once again entered for the third round of the Tequila Patron North American Endurnace Cup, with both are currently listed in utilizing diesel fuel.

With diesel powerplants not allowed in the 2017 LMP2 regulations, the move is believed to serve as a jump-start towards its commitment to the future prototype rules

EDIT: 2017 P2 chassis suppliers have been announced.

They are Onroak, Oreca, Riley/Multimatic and Dallara.

EDIT: NISSAN ARE OUT, until further notice.

The Nissan GT-R LM NISMO has been withdrawn from active racing competition in the FIA World Endurance Championship until further notice, Nissan announced Friday.

Citing what it deemed multiple technical issues, including running without its hybrid Energy Recovery System (ERS) at the 24 Hours of Le Mans, Nissan will withdraw from the Six Hours of Nürburgring, and has not indicated a race when it will return to action in the FIA WEC.

It will instead continue its testing program, predominately but not exclusively in the United States.

“We know people will be disappointed but be assured that nobody is more disappointed than us,” said Shoichi Miyatani, President of NISMO.

“We are racers and we want to compete but we also want to be competitive. That is why we have chosen to continue our test programme and prepare the GT-R LM NISMO for the strong competition we face in the World Endurance Championship.

“When you innovate you don’t give up at the first hurdle. We are committed to overcoming this challenge.”

An updated version of the car completed a two-day test at Circuit of The Americas last month with Olivier Pla and Harry Tincknell at the wheel. It’s understood the car continued to struggle pace-wise at the test.

As previously revealed by Sportscar365, the future of the Nissan program had been under review, following a high-level executive meeting in Japan last month.

Added Darren Cox, Global Head of Brand, Marketing & Sales, NISMO, “We’ve built an LMP1 car that is very different to other racing cars as we continue to drive motorsport innovation.

“The beauty of this program is that people have got behind us and they are willing us to succeed.

“This has shown us once again that people want something different in motorsport and that gives us increased motivation to make our LMP1 car competitive.”

I bet Nissan won't be back at all. or they will after they've had enough time to follow the other manufacturers and go RWD, rear engine and so on...

The 2017 P2 engine rules are interesting. For WEC, ELMS and Asian LMS, the cars must use the control engine which can be badged anyway you want it, just so long as it isn't OEM related. In IMSA, P2 can use any engine they want. The control engine is one of rule changes that isn't really needed.

I suppose the idea was to keep costs down by having a sole developer for the majority since the change to a 600hp unit was necessary, it does make life easier for the governing body when it comes to BOP. The whole IMSA thing does confuse it a little though and perhaps u necessarily so.

The problem with the control engine is mainly that it is totally against the spirit of Sportscar racing, and anti-competitive.

If you were an IMSA team, why would you bother with Le Mans now?

With the IMSA Weathertech Sportscar Series (TUSCs new name) updating the GTD class to full FIA spec GT3 machinery, it should offer more variety in brands than GTLM and Prototype?

Lets just say that Tony Quinn said "I wouldn't mind having a crack at the Rolex 24 and Sebring 12 Hour. I can happily use my McLaren 650S so we'll send it over."

Ideally, you think that it could be as easy a that, but it isn't. If Mr Quinn wanted to do so, he would need McLaren to cough up some money to become an "IMSA approved manufacturer". As Marshall Pruett explains.
