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.
