Via @carthrottlenews - Check out this cryptic announcement from McLaren, involving a totally unexpected partnership with BMW. - In a press release the company has confirmed that it’s working on “new combustion technology that will deliver a higher output per capacity than currently possible.” - The message continues: “It also aims to further facilitate CO2 reductions while simultaneously increasing engine output. - “The technology is destined for future McLaren engines.” - The Woking-based supercar maker is leading a team containing the guys from Munich, engineering wizards Ricardo, casting specialists Grainger and Worrall, Lentus Composites and the University of Bath (obviously). - Speculation as to what the project could entail includes a variable-displacement engine, like those being developed by Infiniti and Honda. It could also feasibly be a camless system like the Koenigsegg Freevalve. Hell, it could be a 2,500bhp V20 that spits out jelly babies and Amazon vouchers, for all we know. - It steers clear of any mention of hybrid assistance, though, and it would have been natural to say so if it was going to feature it, so the smart early money is on the project being a next-generation turbocharged engine to replace the monumental 3.8-litre V8 in the current Sports and Super Series ranges. - This is clearly a big deal, with funding from the UK government and what seems to be a deal to make the technology available to other UK car makers in the future. The assumption has to be that BMW will benefit from the end results, too. We’ll be keeping a close eye on it.
