Mazda's Renesis rotary engine named "International engine of the year"
Mazda is in the news yet again this month. Mazda’s new Renesis rotary engine, the engine powering the new Mazda RX-8 sports car, was named "International Engine of the Year 2003" in a ceremony at Engine Expo 2003 in Stuttgart, Germany. Mazda's RENESIS also captured the top spot in two additional categories, "Best New Engine of 2003" and "Best 2.5-liter to 3.0-liter." The International Engine of the Year is selected by a majority vote of 50 motoring journalists from 22 countries around the world. Judges from the US included editors from leading enthusiast magazines, as well as respected industry analysts. All current production engines from automakers around the world are judged in areas such as drivability, performance, economy, refinement, and the successful application of advanced technology. There are 12 categories in all, including the grand prize, International Engine of the Year. As many as 44 of the judges voted for this rotary engine to become International Engine of the Year 2003 - a new Awards record. The RENESIS engine will power the Mazda RX-8 when it arrives in showrooms in July. The US-specification RX-8 is officially rated at 247 hp at 8,500 rpm and 159 lb./ft. of torque at 5,500 rpm for manual transmission cars and 207 hp at 7,200 rpm and 164 ft./lb. of torque at 5,000 rpm for automatic transmission cars. In addition, the car will meet California low-emission vehicle specifications for those states that require it, and Federal Tier 2 certification for all others. The Renesis engine is unlike any other internal combustion engine in the world, and Mazda is the only company in the world mass-producing rotary-engined production cars. It performs the four processes of intake, compression, combustion, and exhaust in succession by turning a triangular-shaped rotor in a cocoon-shaped combustion chamber to generate the engine power. Compared to traditional internal combustion engines, it is significantly smaller and exceptionally smooth and high revving. The top eight car engines that were voted for are :
Mazda Renesis RX-8
Volkswagen 5.0 V10 TDI
BMW M3
Honda 1.3 IMA Civic Hybrid
Honda S2000
BMW 325i, 525i, Z4 2.5i
Mini Cooper S
Honda 1.0 IMA Insight

isn't it a bit early...we haven't even seen this engine run.....how do we know how it will stant to the real world test?
and btw my favorite "new" engine is the VQ35 encountered in the 350Z

VQ all the way!!! It is used in so many different platforms/chassis and still performs incredibly and is just an all-around awesome engine. In my opinion, it is the best V-6 engine ever produced on a large scale.

Hell no it doesn't, while it is incredibly impressive for a rotary, it still has the typical rotary problems, there's many engine that deserve that title moreso, especially if the 3.6L V6 from GM gets released this year.

It may still have the "typical" rotary problems - but it doesn't have the typical piston engine problems - why the hell hasn't anybody made an engine with a scotch-yoke crank yet?

Typical piston engine problems? like what? The RX-8's roughly the same weight as a C5, siomilar aerodynamics and still makes the same mileage, all on a 1.3, or 2.6 depending on how you view rotaries.

The 3.6L V6 is shit. My brother's car has it and I can't think of a more unreliable, unpowerful, piece of crap in any V-6 I've driven.

heh, er, sorry bud, but the 3.6L V6 doesn't exist yet, it'll first debut in next years CTS.

DOHC continuous variable valve timing, a very efficient chamber and piston design burning almost all of the injected fuel. 3 pairs of oil jets cooling the pistons, a very conservative 260 hp and equal torque stock, it can easily do much more if they feel like it, the cam is likely the limiting factor there. Forged rotating assy, oversquare build, etc etc either way it's going to be a global engine, very potent and can meet any emissions changes that are upcoming. If they put the same talent into the 4.2L I-6 thats won so much praise then it'll easily outpace any current V6s, the 4,2L now is still the best I-6 on the new market , I'd even argue old markets as well.

Then what was the 3.6L engine released in GM's early 90's sedans? Like the Oldsmobile Cutlass, Pontiac 3000, and the Chevy Corsica?

Talking about the engine not the car. Rotary engines, have less moving mass (and the rotors don't have to change direction either) no camshaft, or valves etc. - those sort of problems.

Pity they still break down with all those fewer parts.

the 3.8L is still one of the best V6s ever made, never seen a GN have you? my 3.8L has been nothing but reliable, as have most of them, you must've gotten a lemon, it's well known how reliable and how much potential they've got.

From my experiences with this engine in 3 cars, I'm not impressed by it. But I may have gotten 3 lemons as you say......

What happened with them? the reason that motor still exists is becaus it's design is so simple and cheap to make while being plenty reliable. GNs have proven their power potential and ease of modding.

The transmission went and then we got it replaced and the alternator went, then it starting hesitating because water got into the gas. We just sold it recently. Oh, BTW, it was a '91 Oldsmobile Cutlass Ciera S.
the other two belonged to a friend and a family member.

Break down? - reliable, but short lived (face it, the 4-stroke-cycle piston engines used in cars weren't even as reliable when they were this old) Think it's good that Mazda has stood by a great design for so long, without them the wankel would've died along with NSU.
