We all thought the new R18 e-tron would have a much more developed 3.7 litre V6 turbodiesel underneath, upgrades to the flywheel accumulator system and an exhaust heat recovery system. Narrower by 10 cm from the previous R18 e-tron and the new R18 has will do 30 percent less fuel than the pervious R18 e-tron when race next season.
But, during Audi launch (25/3/14) of the R18 e-tron quattro in quattro livery colours this time at the city of Le Mans. Things has changed a bit.
For starters the cubic capacity of the V6 TDI turbodiesel underneath was increased from 3.7 to 4.0 litres in order to further optimise the engine.
And the exhaust heat recovery system which is similar to what underneath a F1 car this season is gone after system did not offer the gains that had been hoped for in testing and that there were concerns over its reliability. So it will only keep the the flywheel accumulator system this season (KERS). And that means the new Audi R18 e-tron quattro will have just one energy-retrieval system rather than the permissible two. That means Audi will use two megajoules of hybrid power through each lap this season. Compared to Porsche, will use eight megajoules of hybrid power through each lap with the Porsche 919. And Toyota will use six megajoules of hybrid power through each lap with the Toyota TS040 Hybrid.
Audi have also announced the driver pairings for the FIA World Endurance Championship and 24 Hours of Le Mans campaign this season, Tom Kristensen, Loic Duval and Lucas di Grassi will drive the #1 car this season. Andre Lotterer, Benoit Trelyer and Marcel Fassler will drive the #2 car for the whole of 2014. And Oliver Jarvis, Marco Bonanomi and Filipe Albuquerque will drive the #3 car at Spa and Le Mans rounds only.
A challenging season ahead for Audi.
End of post for now, new post soon. Bye.
