Default Sorry Corvette guys Audi V6 TDI Diesel Hybrid wins Lemans

Sorry Corvette guys and lovers of old tech American V-8 I am glad to see change coming. I have a VW Jetta TDI diesel that is phenomenal.

************************************************** **
Audi R18 e-tron quattro hybrid with flywheel energy system wins Le Mans; first hybrid win there
18 June 2012

Marking the first victory of a hybrid vehicle at Le Mans, the Audi R18 e-tron quattro (earlier post), equipped with Williams Hybrid Power’s (WHP) electromechanical hybrid flywheel system, took the top two spots at the 80th running of the endurance race over the weeken. The win was Audi’s 11th Le Mans victory. The four Audi R18 cars (two hybrid, two diesel) from Audi Sport Team Joest occupied positions one, two, three and five.

Operating at the rear of all four Audi R18 cars was the latest evolution of the compact V6 TDI engine with VTG mono turbocharger that was used at Le Mans for the first time in 2011. The new ultra-light transmission with a carbon fiber housing held up to the Le Mans endurance test covering a distance of 5,151 kilometers in all four vehicles with no problems, the company said.

The engine is a 3.7-liter turbocharged (boost pressure limited to 2.8 bar absolute) 120° V6, 4 valves per cylinder, DOHC diesel direct injection TDI using a fully stressed aluminum cylinder block and equipped with a diesel particle filter. The engine delivers power of more than 375 kW (510 hp) and torque of more than 850 N·m (627 lb-ft).

WHP designed an entirely new, ultra-lightweight electric flywheel and associated power electronics for the Audi R18 e-tron quattro, working closely with Audi engineers to fully integrate the system into the car. The system provides 150 kW of power and has a top rotor speed of 45,000 rpm. The key features and benefits of the WHP system are highly suited to endurance racing and this made the WHP flywheel the prime candidate for Audi’s project when compared to other technologies such as batteries, ultra-capacitors or mechanical flywheels, WHP said.

One vehicle axle (rear) of the R18 e-tron is powered conventionally, the second (front) by two water-cooled 75 kW motors with integrated power electronics. The system integrated into the front axle includes two drive shafts, the Motor Generator Unit (MGU) supplied by Bosch, planetary gearset, the WHP KERS system, an insulation monitoring unit for high voltage safety, and the control system.

On the Audi R18 e-tron quattro, kinetic energy is recovered on the front axle during the braking phase. In the process, the wheels drive the MGU. The braking zones permitted are defined by the controller. Power from the Motor Generator Unit accelerates the carbon-fiber flywheel, which runs in a high vacuum.

After the corner is taken and the driver accelerates again, the system delivers the energy to the front axle. The regulations allow 500 kJ of energy to be transferred to the front wheels between two braking phases. The planetary gears adapt the transmission ratio during acceleration and braking. The two independently powered axles on the e-tron quattro are synchronized exclusively via electronic control strategies.

This control occurs automatically without driver intervention. The entire charging process (recuperation) is controlled by two parameters: the deceleration of the car—i.e., the braking process—and subject to the accumulator’s state of charge. The energy emission process (boost) is defined by the minimum speed of 120 km/h stipulated by the regulations, the race strategy selected, the throttle pedal movement and acceleration of the car.

I'm an Audi fan but the R18's (LMP1) were not even racing the Vettes (GTE). Thats like comparing F1 to NASCAR.
Additionally, with Peugeot not even entered in the series, the Audis didn't even have any real competition.

Don't see the F1/NASCAR comparison. Cup cars have more HP and are as fast as F1 cars plus Cup cars can run long periods at sustained speeds, F1 cars can't.

In any case the Audi's finished 1-2-3 over all. The closest Corvette was in 20th place 49 laps back.

Endurance racing isn't about maximum speed, it's about endurance. F1 runs maybe 2 hours...NASCAR maybe 3-4 hours. 24 hours LeMans/Daytona is like a whole season of F1 racing crammed into one non-stop day.

Outstanding achievement for Audi. What was the ground covered...3,000 miles or so?

Good guess. It's 3,200 miles.

The audi's and the corvettes are in different classes, how on earth can you compare them? Lets get real. And F1's are nothing like nascar's.

They were in the same race. Audi finished first, best Corvette was 20th and 49 laps down. Simple facts.

I did not say Cup cars are like F1 cars. Somebody else brought up F1 and Cup. I pointed out the differences ie Cup cars greater power, speed and endurance than F1 cars.

I dont think you understand how this form of racing works, the Corvette wasnt racing the Audi, the Corvette actually lost to Ferrari.

I own 5 Audis and have a Porsche 911 C4 in the works. Love them all, one with 197,000 mile, an A6-will be buying an R10 as soon as I can...

Do you have any understanding of how the Le Mans works? So far off based. Thats like saying a commercial trawler caught more fish then a guy in a row boat with a singe line and a hook. They are both fishing........ And since last year 2 Audi's didn't finish so corvette beat 2 Audi's last year? come on

Just like F1 and cup cars are different the Audi and corvette were in different classes.

They weren't even competing in the same class. Audi races in LMP1 the Corvette was in the GT class.

It think it's pretty impressive that a pushrod 2 valve V8 can compete with cars with 4 OHV motors.

I got my cup on!

F1 has deteriorated into a technological showcase..very few holders of supertickets are truly podium material. I find myself snoozing through F1, but I'm glued to the set when NASCAR does Watkins Glen or Sonoma.

I'm glad to see Audi improving its quality..had a mechanic friend years ago who called them "Cars from Mars"..he said martians dropped them on the earth at night for unsuspecting people to buy. Diesels will always be capable of making more power..the fuel has more energy per gallon, and the compression is higher so they are more efficient. Making them last is the trick.

In any case Audi deserves congratulations!

About like bringing a Harley to a motorcycle race.

I have been around cars all my life and have worked on a lot of them in the past but there is no way I am touching anything under the hood on my TDI Jetta. It has a long warranty.

If anything happens to it I will wait for the mothership to come in and fix it.

I watch both and enjoy both NASCAR and F1. They are just different. Both have grown to have way too many complex rules but then what hasn't in today's world?

Pretty soon race teams will need official litigators at the track to handle filing injunctions during the event if we keep going this way.
