Dont forget that the bizarre way Mazda seem to think they can rate their engine the 1.3Ltr actually sucks in and burns 3.9Ltr of air and fule every revolution of the rotor.
This means the "2.6Ltr" race motor is actually over 7.8Ltr which make the performance look 'unsuprising' which is probably why they like to 'suggest' its so much smaller than it really is.
Once you start adding turbos you can have any power you want...within reason obviously.
You cant really measure it that way either.This means the "2.6Ltr" race motor is actually over 7.8Ltr which make the performance look 'unsuprising' which is probably why they like to 'suggest' its so much smaller than it really is.

Unless you want to quote engine size at a particular atmos pressure, RPM and BHP output. Its fairly obvious that the engine size will not change after a remap yet your car will likely use more air / fuel. Or by bolting a turbo on, you will not increase the engine size yet loads more air and fuel will be used.
The physical size of the engine will not change when the efficiency of the burn is changed.
IIRC mazda have filled one of their rotor chambers (?) with liquid and quoted that as the displacement, i.e. the volume of the engine.
0-500 kmh in 6.1 seconds is not much slower than a top fuel dragster, which has 7000hp, huge tyres and almost certainly weighs less. I think someone might be having a little joke at PH's expense here.
I would also expect any green credentials from it's bio-ethanol fuel to be negated by the need for the rotor tips to be regularly doused in oil, which is then burned. Ask any Mazda RX owner about the green credentials of rotary engines.
If they're going to all this effort, why not just use a gas-turbine from a helicopter and run it on bio-diesel? you could easily get 3000 shp from a Sikorsky Skycrane engine. I can't imagine an 8-rotor wankel motor would be any more efficient, and then you don't have the cost of designing a new engine.
...however, this will never be built anyway.

It's about time car companies started making properly ultra light road cars instead of chasing silly numbers. Not a single company has made something truly ultra light. Maybe something like an Atom, but with no steel, iron or other cheap tat used at all. For example you could use a pure titanium space frame chassis, every bolt and widget would be titanium or carbon, CNC'd to save every possible gram. With attention to detail and weight obsession only seen in bicycles or radio control. Keep it extremely simple, focus on every detail and I guess it may be possible to make a car half the weight of even an Atom.

Here we go, a bit more info from last year:
It will be offered in GT S, RS, RSR and N-Spec versions, all powered by a Mazda 13B MSP, high-performance engine with four rotors (4-Rotor rotary engine) and, depending on the model, a water-to-air intercooled turbo or biturbo system. Output ranges from 500 HP to 1200 HP for the high performance version. The engine is mated to a sequential 8-speed RSC R-SHIFT transmission controlled by a hydraulic shift system with shift times of 25-35 milliseconds.
Depending on the model, the body is of 80% glass fiber or carbon fiber and differs in details in the form and aerodynamics. The interior will get two 7" full-graphic-Diyplays, high-quality materials like carbon fiber, brushed aluminum and various types of leather
The RSC Raptor ™ GT S, RS, RSR and N-Spec does not have a conventional drive system as used in most of today’s super sports cars. He has a self-developed and heavily modified, based on parts of the Mazda 13B MSP, high-performance engine with four rotors (4-Rotor rotary engine) and, depending on the model, a water-to-air intercooled turbo or biturbo system. This engine is the heart of the RSC Raptor GT™ and gives him his very special temperament. The power output of a rotary engine uniformly grows with increasing rpm. The high-performance engine in the RSC Raptor GT™ has the redline set depending on the selected driving mode, up to 7,500 rpm or 9000 rpm. The fuel E85 is used, which is produced from rapeseed. By using this fuel to reduce the emissions by about 90% is feasible.
The sequential 8-speed RSC R-SHIFT transmission in the RSC Raptor GT™ is controlled by a hydraulic shift system with shift times of 25-35 milliseconds. Furthermore, each RSC Raptor GT™ has a carbon-aluminum drive shaft, and an electronically controlled rear axle differential.
The powertrain is controlled by an engine management system, specifically developed from Bosch Engineering GmbH for the RSC Raptor GT™, including a complete electronic system consisting of ESP, ABS, EBD, VAS, R-TRAC (traction control), R-DIFF (electronic differential) and a Launch Control. The RSC Raptor GT™ RSR and N-Spec also has an active suspension. All electronic systems can be easily operated via the buttons on the steering wheel.

It makes you wonder how they are going to feed in enough apex seals per second for 2800hp.
Don't you know they're made of hyper-diamond reinforced unobtainium? 
They're good for 200k miles of use at full power too..........or at least they will be until they try and do anything they've mentioned and realise it's a load of horses
t.This is utter bs. Either a real Walter Mitty character or a 14 year old with some good 3D rendering skills.
A Bugatti Veyron can achieve 1.55g sustained. This claimed 3g acceleration equals the Space Shuttle on launch, and to achieve anywhere near those acceleration times, you'd need north of 5000bhp. There's no way you'd get that reliably from any IC engine.
You've also got to ask yourself why a company that has such apparent talent for engineering can't write sentences that make sense on its website.
A quick search of the names quoted on their website also returns this Facebook profile for the only person named Moritz Benner:
https://www.facebook.com/profile.php?id=1000019166...
And this LinkdIn page for Darren Wattez
http://www.linkedin.com/in/darrenwattiez
Moritz seems to resemble a 15 year old and Darren appears to be incredibly unfamiliar with punctuation for someone with a PHD and 23 years experience in Military Engineering.
Their press release claims they're getting Bosch Engineering to do their ESP application. This is indeed the correct company to do that job and it just so happens that I work with a number of the Bosch ESP development engineers so I shall fire an email to one of them tomorrow and ask the question as to whether there's any truth in this. I'm sure they'll be interested to know if their name is being linked to something if it's made up!
I'll report back!

We serve an extremely young, but getting constantly more important segment of the car market with our models having a performance output of 1200HP with emission standards comparable to a car with ~120 HP and the ceasing of sulphur dioxide output.
Furthermore, rotary engines are by their very nature incredibly inefficient. The very physics of the design mean that the expanding combustion chamber is hugely thermally ineffective. If you were going to get that kind of economy from an engine, you would choose something running the conventional otto cycle.A quick search of the names quoted on their website also returns this Facebook profile for the only person named Moritz Benner:
