I have read this thread with great interest, all the discussions about DOHC, transverse engines, AWD, flatplane crank V8s, etc. Actually, I'm lying, it was so tedious mainly because it is missing the point.
The thing about modern touring car/saloon car/sedan racing is that it is all about providing a safe spectacle. There's been a move by many major tin top series to make cars safer and at the same time provide a set of regulations that can equalise performance. Throw in shared components to lower costs and you have your modern racing touring car. So if you are worried that a car's performance has been throttled or a car doesn't relate to the road car it is supposed to represent, then Im afraid that's just tough.
In Britain, we are looking forward to a 30 plus grid of 'NGTC' spec cars this season in the BTCC. Cars from MG, Honda, Ford, Toyota, Mercedes, Audi and Proton. A set of rules that promotes development of diverse cars through shared components - sub frames, gearboxes, wheels, wiring looms. Hell, if you haven't got the right engine for the job you can buy an unbadged spec engine from the series organisers and plug it in. But you won't get people bleating about how it doesn't compare to the road car, mainly because the spectacle is worth the conceit.
About the only main touring series which considers the purity of the cars recently was the WTCC, which in recently has been all about which was the fastest guy in a Chevrolet. Now that's dull.
It's all about the brand these days, not what's under the bonnet.The biggest 'win on Sunday, sell on Monday' event is the Le Mans 24 hours. Are you telling me you can get a Porsche 919 in the show rooms? Now I'm partial to WEC mainly because of the technological challenge, but I watch Touring Cars for the spectacle.
Anyway, back to Adelaide. Anybody who didn't hold their breath as the Volvo snuck down the inside needs to have a lie down in a dark room. That was racing!
