All New MZR-R Engine

MAZDASPEED engineers in the U.S. and Japan, in conjunction with U.K. based Advanced Engine Research Ltd (AER), will debut an all-new MZR-R prototype engine at the 2007 12 Hours of Sebring. The new engine, a clean sheet design, is a turbocharged 2.0 liter in-line four cylinder. The performance goals for the engine are 500hp and 400 lb-ft, with the durability to succeed in such grueling races as the 12 Hours of Sebring and the 10-hour Petit Le Mans. The engineering team is working to incorporate the production-based Mazda Direct Injection Spark Ignition (DISI) system into the race motor. The technical collaboration between Mazda and AER has been non-stop in preparation for the season- opener at Sebring.

MAZDASPEED Motorsports Development Manager Steve Sanders stated, ?Given the rules package, we needed to make a radical change to be able to match the competition. The current conditions and rules simply do not allow our rotary engine to have any competitive advantage, hence the move to piston power this season.?

Sanders continued, ?The Mazda and AER engineers are working closely with Honeywell Turbo Technologies on the development of a new Garrett motorsports turbocharger design for this engine program. The overall LMP2 program is driven by Mazda engineering, as we use motorsports to help develop future advanced technologies with the potential to transfer over to our production vehicles.?

Mazda remains firmly committed to the rotary engine, in the street-going RX-8 four-door sportscar and racing classes like Grand Am GT and the one-make professional Star Mazda formula car series.

While the new engine will be exclusive to B-K Motorsports in 2007, the long-term goal is to add teams in both the American Le Mans Series as well as the Le Mans Endurance Series in Europe in 2008.

You'll find its pretty common; production engines being substantially re-engineered for motorsport use. One example I can think of is the Rover V8. Competition versions used in, for instance, TVRs, ad redesigned (stronger) blocks, competition pistons, cam, crank, big end shells etc, leaving not a lot left of the origjnal lump. Other obvious examples are the families of GM and Ford V8s which end up at 1000hp+ drag racing engines. The blocks tend to be all new.

Its rare for a competition engine to end up back as a road engine. There was talk of a Lola 2.0L four pot, used by MG at Le Mans, beng installed in the MG-TF. They got as far as a few road legal prototypes. But the usual problem is these engines won't meet international emissions standards.
