WEC (World Endurance Championship) 2014

As far as how is torque an advantage, have you ever pushed the throttle to the floor on an off boost turbo engine? Torque is good.

You don't mean Torque. what you mean is "mid-range power".

You could say that, but diesels, by nature, run at lower rpm. A lower revving motor, will always make more torque to equal the same HP, because, as we all know power is torque times speed. So , in general, if you have diesel and gasooline motors of the same peak power, the diesel will have greater torque. A diesel does generally have better mid range as well, though.

Don't try to tell me what I mean or don't mean.

Edit: Man it sucks to start a new page!

Diesel's might efficient but there's nothing "green" about them, their carcinogenic fine particle pollution is actually far more toxic (proven to cause cancer) than the gasses emitted by petrol engines.

Diesel particle filters are state of the art and push the toxic dust level down to other types of fuel. This is a pseudo problem which the industry has long solved.

Sorry mate but that simply isn't true, the particulate filters are only 95% effective.

And once again you are making assertions without any sources to back them up. On top I might say you simply focus only on emissions of diesel engines and fail to mention that petrol cars also emit particles as well as other harmful emissions. IMO there is no reasonable justification for your bias against diesels in the WEC. Half of Europe buys passenger diesel road cars nowadays and so the propulsion design is very relevant for the manufacturers and the FiA. The WEC is the top racing series that has road relevance and we should not forget that.

Don't want to get off topic, but if two engines make the same peak power, and (for arguments sake) the same mind range power, who cares which one makes the most torque?

a turbo charged engine generally have wider mid range, it is not limited to diesel

and greater torque just means you need a bigger clutch and different gear box ratios, power is power

Diesel is a far less refined fuel than petrol and that is why it produces soot and carcinogenic fine particles, petrol isn't perfect but it doesn't produce either of those byproducts!

The wide use of diesel in Europe is down to one factor, economics! Petrol is artificially expensive making diesel much more attractive.

In most countries outside of Europe, diesel is either priced the same as petrol or slightly higher than petrol.

This is laughable and not supported by scientific evidence at all. Environmentally and health endangering aspects of exhaust fumes are not proportional to the volatility and refining level of the fuel. There are many factors that play a much bigger role. The cleanliness of the combustion and the application of the catalytic filtering technology together with the use of carcinogenic fuel components and the absorption of displaced fuel tank gases in the first place are much more important for health aspects.

..petrol isn't perfect but it doesn't produce either of those byproducts!

wrong again! if you burn it badly and don't filter it with a catalyst, petrol exhaust has very bad emissions particle wise and by other components.

you are having your facts ass to face as usual. Turbo diesel engines are superior in terms of resource conservation because they have a higher energetic efficiency and deserve an economic advantage in terms of fiscal treatment. The European governments are simply trying to minimize the dependency from imported fossil fuel by promoting the higher efficient power units and aim at having the best motor industry of the world. at the bottom line cars on the European continent are on average more fuel efficient than cars on any other continent on earth and it shows in global competitiveness. WEC is the race car laboratory for the best European factories which includes the Toyotas, made in Cologne, Germany.

Rarely is anything as black and white as you want it to be.

A climate mitigation policy that focuses on CO2 emissions supports an increase in the fraction of diesel cars because passenger cars equipped with diesel engines emit on average 15% less CO2 per kilometer than vehicles with gasoline engines with a similar power output. After the UK had begun taxing vehicles according to CO2 emissions, the share of registered new diesel cars increased from 26% in 2002 to 38% in 2005.

However, it is not clear whether the shift from gasoline to diesel cars, which is encouraged by CO2 taxes for vehicle registrations and fuels, would be effective as originally intended as a climate mitigation measure, given a number of non-CO2 components emitted together. Many of them have indirect climate effects through chemical reactions or by changing the planetary albedo. NOx, CO, and HC emissions lead to a production of O3 (“short-term O3 formation”) as well as a change in the levels of the main oxidant in the atmosphere, the OH radical. NOx emissions and the produced O3 enhance the production of OH, while CO and HC emissions reduce OH levels. The change in the OH concentration affects the lifetime of CH4, which has a longer-term impact on the O3 production (“primary mode”). BC and OC absorbs and reflects sunlight, respectively (direct effect) and BC changes the albedo of snow/ice (albedo effect). BC and OC may also change cloud properties through the indirect and semi-direct effects. Furthermore, aerosol abundances are influenced by OH through gas-aerosol interactions.

Some of these personal comments are about to get out of hand: "you are having your facts ass to face as usual" is over the line. "laughable" and "boorish" aren't as bad, but let's not go any farther, please.

Also, please don't turn this thread into Green Debate III with technical details about various pollution technologies.

Why Audi has chosen to run a diesel engine in WEC, is a good topic to discuss.

The wide use of diesel in Europe is down to one factor, economics!

Diesels racing at Le Mans
Audi's decision to use a diesel engine emphasizes the commercial success of Turbocharged Direct Injection (TDI) turbodiesel engine (and its competitors) on Europe's roads. Diesels have been successfully used in other forms of racing as well, as their broad power band and fuel economy can prove advantageous.....

2014 Audi R18 e-tron Quattro Le Mans racer consumes about 40% less fuel than first TDI engine at Le Mans in 2006

Any company that has anything to do with logistics (transport, wholesaler, retailer, public), would be very interested in any savings to do with diesel engines, IMO. With WEC being far more 'relevant' for manufacturers, as a platform to display a winning solution, it's far from being terrible.

Don't want to get off topic, but if two engines make the same peak power, and (for arguments sake) the same mind range power, who cares which one makes the most torque?

Perhaps the "motor" journos , like Jeremy in Top Gear, and certain self-appointed gurus in forums such as this?

..... please don't turn this thread into Green Debate III with technical details about various pollution technologies.

the apparent diesel hazard to health is mostly from heart attacks and strokes, not cancer
eg UK officials believe diesels kill most of the 29000 Brits (+60000 Germans) annually judged to have died from atmospheric pollution
that is city dwellers dying earlier than countryside dwellers
significance is given to particulates smaller than 2.5 microns, because these cannot be contained within the blood vessels

we apparently should believe these earlier deaths are not caused by eg the stress of city living and 'stress junkie' lifestyle
but entirely by the higher atmospheric pollution in cities

hoping that Mr Mod can live with this post
(or detaches all the health-related posts from this thread)

Anyone know if the LMP1-L Lotus will get on track this year?, they keep pushing it back and back, it would be nice to see a team fighting rebellion instead of them being on there own in no mans land.

If they are using Renault power, they're probably putting it on hold.
