The valves sound like they are ticking in the front of the car.
I have THX headphones. When the car made the pass, I could hear the valves ticking followed by the rear tire tread humming milleseconds later, too long for the engine to be mounted near the rear tire. Mid engine would almost have the two sounds overlapping. That would lead me to believe it's FWD.
I'm sorry, I meant front engine. Duh! But now that I've watched the video again, I can hear front and rear axles as well. So not only is it front engine, but it's SH-AWD.
From the above link:
"When the unimpressive Acura Sports Car Concept debuted at the Detroit auto show in January, most thought it was a glimpse at the next-generation Acura NSX. Since then, Honda has been silent about its upcoming V10 supercar. Not anymore.
Wearing heavily modified S2000 sheet metal and riding on a platform with an extended wheelbase and wider track, the front-engine V10 test mule broke cover on Germany's famed Nürburgring test track. And like the upcoming GT-R supercar from Nissan, this Honda prototype was paced around the track by a Porsche 911 Turbo, proof that Honda means business"
If it's a front engine "modern muscle car" as opposed to a mid engine exotic sports car as it clearly appears, I place my bets on a total failure. There is too much competition with front engine high horsepower sportscars for Acura to make a dent. Honda has great engineers, but poor designers and marketeers. Just take a look at the Civic, Accord and RL. Amazing products with no point of view or personality. A front engine "muscle car" from Honda sounds like a waste. I'd rather supercharge my '91 NSX or buy a GT3 or track prepped Z06.
Just my humble opinion.
