Tom Kristensen, Loic Duval and Alan McNish have won the 2013 Le Mans 24 hours race in the Audi #2. The Toyota #8 finished in second place, followed by Audi #3.
Any idea what bank angle?? 90° would be logical for a V4. But larger angle could also be useful with lower CoG.matt21 wrote:I´ve read this as well, but the position of an exhaust for me is no indication on the type of engine.
As you can see on the picture the fin is placed at the car center line, so they have to go for side shift for the exhaust.
For me from an installation point of view (dimensions, strength etc.) an I-4 makes no sense as long as you don´t have to go for a stock block engine or for marketing reasons.
I have said it before and I am still of the same opinion: Porsche are serious with their attack on LMP1 an will create the most fuel efficient petrol engine we have seen in racing for decades. And I'm totally convinced it will have no more than four cylinders. This single exhaust is just another hint in a long line of indicators that the VW/Porsche/Audi group is dedicated to a high tech I4 for their next break through design. It was meant to come in F1 but they have now shifted it to WEC and LMP1 because F1 is so backward it makes no sense to compete there.Saribro wrote:'Mulsanne Mike' has speculated an I-4, due to off-centre exhaust.

They're still 13 seconds a lap slower than F1 around COTA, probably be significantly more this year as the circuit was very dirty last year.kooleracer wrote:I watched the race in COTA last night. These LMP1 cars look like rocket ships, its just incredible to watch. Also was really surprised to hear that the LMP1 cars on low downforce spec have even more downforce than F1 cars on high downforce spec, according to alex wurz. I really dissapointed in F1, the WEC has everything right. I cost less, the is actual racing going one, and they're doing actual R&D for roadcars. The tyres always gives performance. Was really nice race to watch. The COTA circuit is just brilliant. Maybe next year the LMP1 cars will be fastest race cars, with F1 switching to 1.6 V6 engines. LMP1 cars have TC, why FIA banned TC in F1. TC is used on a lot of road cars these days. Its just silly that the F1 cars don't have it anymore. I really loved to sound of the TC.
Something like 12.5 seconds slower in Q, but the fastest racing lap was only ~8 seconds slower than F1's fastest racing lap. Having the same fueling rules & tires would likely move that difference in favor of F1 though.Cold Fussion wrote:They're still 13 seconds a lap slower than F1 around COTA, probably be significantly more this year as the circuit was very dirty last year.kooleracer wrote:I watched the race in COTA last night.

When you write like that do you mean 750 + 80 ? Cause next year the KERS/ERS will be added so its upto 750 for the whole package and not ontop like now for F1 that is, if we are to compare further on for next year.Blanchimont wrote:And don't forget the differences in weight and engine power, these two parameters can explain a lot.
F1: ~645kg in Q, ~750hp (+80hp KERS)
LMP1: ~915kg in Q, 490hp (+2*109hp) Source
In that video the audi short cuts rettifilo.... Makes the shot going around curva grande amazing.Blanchimont wrote:These numbers are for a 2012/13 spec F1 car and for a 2013 LMP1 Audi, nothing about 2014 here.
And for LMP1 top speed...

Several nights before the International Sports Car Weekend at Circuit of the Americas in Austin, Texas—the American Le Mans Series on Saturday, Sept. 21, the FIA World Endurance Championship on Sunday, Sept. 22—FIA officials summoned COTA management to a hastily called meeting. The officials proceeded to slam them mercilessly, claiming this was one of the worst-promoted, worst-run races they've seen; that they expected this in China, but in America? Where their sophisticated Audis and Toyotas should be playing to a packed house in their only appearance here this year? Not acceptable, and we wondered if the WEC's three-year contract would see year two. This was days before the races even started.
Friday, rain trimmed the crowd, but on Saturday and Sunday, the weather was perfect. COTA claimed a three-day crowd of about 35,000, which seems optimistic. Near the end of Sunday's WEC race, it is simply not possible to claim there were more than 5,500 fans there. The ALMS, with its familiar Corvettes and Vipers and comparably loud cars, outdrew the WEC significantly. That's item No. 1 you should know about.
