Toyota officially presented yesterday the new Hypercar which will take part, with the same crews as last season on the LMP1 cars, in the World Championship and the Le Mans 24 Hours. The new Hypercar regulation is something I have been eagerly waiting for.
Apart from the look of the ambiance, the cars, the speed, the racing one of the most aspect and enjoyment of motor racing is the sound. There are some iconic cars. I think my favorite in the Matra 650 or 670. The sound of that V12 engine has never been equalled.
My favorite cars
The car took part in the Le Mans 1964 edition. The Panhard’s drag coefficient (Cx) was a never equalled 0,12. The car was retired after 10 hours.
It certainly was a beauty.
The Ford GT 40s dominated in the late sixties.
Only a few days left before the real start of the super season and the first race in Spa.
Having seen the cars earlier this month at the prologue in Le Castellet, I am really looking forward to see if the Toyotas will have an advantage on the privateers LMP1. I am also looking forward to the newcomer BMWs in LMGTE Pro. The whole LMP 2 field is also exciting as usual.
Anyway this is always exciting as this is the real race conditions before Le Mans 24h in June. And as we all know, nothing is comparable to Le Mans.

At the 6 Hours of Spa, the Audi R18 e-tron quattro debuts a new bodywork configuration. It differs significantly from the version with which Audi won the FIA World Endurance Championship WEC season opener at Silverstone. Jan Monchaux, Head of Aerodynamics at Audi Sport, explains the background.
In the meantime it has become a small tradition for Audi to develop different bodywork configurations to be perfectly equipped for the high-speed Le Mans circuit where average lap speeds exceed 240 km/h. To compare: on the track in Shanghai, which is scheduled for November, the drivers reach an average of only 180 km/h – this is an average of 25 percent less.
While the visual changes in previous years were barely recognisable to the untrained eye, Audi has consistently followed a different path since 2013. “The long tail was an effective distinguishing feature for the public,” says Jan Monchaux. Together with his development team, he developed a bodywork version specifically for the 24 Hours of Le Mans. This configuration finished flush with the rear wing and at the same time contained many more detailed solutions. The goal: significantly lower drag by omitting downforce, in order to be better equipped for higher speeds. Downforce is the force that aerodynamic components create. It presses the race car onto the ground and, as a result, permits higher cornering speeds.
When the version that creates less downforce runs for the first time this year at Spa, the differences to the sister specification, which generates higher downforce levels, are more apparent than ever before. A fundamentally different front fairing, modified sidepods, openings relocated on the inner surface of the rear fenders for venting the wheel arches, and the bodywork rear edge featuring an unusual rear wing support, characterise the newly developed race car.
“Because downforce at Le Mans is not as important as it is at other tracks, we developed other solutions and new body shapes,” says Monchaux. “In this way, we reduce the drag. All the turning vanes, wings and similar elements are no longer mounted so steeply in the airflow; the curvature of the wing profile is less.” In addition to the bodywork surfaces, the technology beneath is also affected. “The cooling system’s requirements are different. We were able to reevaluate and adapt the flow across the cooler, because at Le Mans less air mass flow is necessary due to the higher speeds,” he continues. New suspension solutions, which restrict the spring displacement on the car to a smaller range, provide additional help. In this way, the turbulent airflow under the race car is reduced.
With the sum of all innovations, Audi further improves the efficiency of its hybrid sports car. “We expect to benefit from this and to be able to use these advantages on other race tracks,” says Jan Monchaux.
Audi has released the first image of its 2014 Le Mans 24 Hours challenger ahead of a test starting at Sebring.
The image shows that the car built to the new LMP1 rulebook retains a close resemblance to its predecessor, whose R18 e-tron quattro moniker it retains, despite regulation changes that mean it is five per cent narrower.
Here is another one which makes you shiver. The 1968 GT40 #6,driven by Jacky Ickx and Jackie Oliver, just about to enter Tertre Rouge before the Mulsanne straight.
