After countless spy photos and appearances at auto shows for the past several years in two different styling forms, the Lexus LF-A made its first official appearance on the road this weekend at the Nürburgring 24 hour race. At some point during the weekends festivities, Automobile managed to snag a shot of the engine lurking under the race-prepped Lexus' hood. We can't derive a lot of details from this single shot, but we can get a few tidbits.
Looking at the area behind the intake plenum near the firewall on the driver's side, the engine looks long enough to likely be a V10 as has been previously postulated. The bank angle appears to be 90 degrees for a lower center of gravity than would be available from the normal 72-degree bank angle for a V10. The intake plenum is apparently made up of a composite material, again, likely for both overall weight reduction and and lowering the CG. Under that however, the intake runners appear to be metal. Finally the engine is set well back in the chassis for a front mid-engine layout, almost entirely behind the front axle line. Now that the LF-A has hit the track in anger, maybe we'll see it in production form soon, perhaps even at the Paris this October or Geneva next year.
