I've watched NUMEROUS Best Motoring Video's where they have 5-10-30 lap races and various wet skidpad, and Autocross runs with all of the JDM supercars.
The Skyline GT-R R34 V-Spec CONTINUOUSLY comes up as being one of the strongest runners. It has excellent cornering capabilities, a VERY strong motor, and very neutral handling characteristics. In most of the races that are performed by BM, the GT-R and NSX S-zero are neck and neck all the way until the end, You can never tell which one will win the race.
It IS based on a sedan platform of sorts, but is no more like the garden variety Skyline than a Prelude is like an NSX. Most of the driver's who are all quite skilled (Kurosawa Motoharu, Tsuchiya Keiichi etc etcimpressions, ) say that the Skyline IS a bit heavy, but is definitely a contender for Japan's Supercar Crown.
During the last 30 lap enduro battle they had, the Skyline was the most consistent and was voted the best car overall. The conditions for the race were that you could not exceed the manufacturer's spec's of 110C water temp, and 130C oil temp. If you exceeded any of these for 3 laps in a row you were penalized a lap.
1st heat (15 laps) 1st place RX7, 2nd Skyline, the NSX was DEAD LAST due to oil temp problems. It was STRUGGLING to keep under 135C.
Again in the second heat (15 laps) The Skyline took first, and the RX-7 second..NSX? Dead Last again due to oil temp and water temp....
After all was said and done...I still bought an NSX...ALL HAIL THE NSX!!
Sorry about the long post. btw I can try to get MPG clips of these races if you'd like...
