I have run hundreds of laps on the best road courses in the East and there are frequent blown engines especially on the long tracks like WGI not to mention the all to frequent encounters with the walls.
I will admit that in drag racing the starting line can be pretty violent especially with manual trans starts but with so many running automatics these days the starts are pretty calm, provided you keep the front wheels on the ground.
I think all kinds of racing is pretty rough on engines and drive trains I just think road racing is a little rougher.

I would agree with your assessment. Having done drag racing, auto-x and road courses I would rank them in that exact same order (least to most) in terms of wear and tear on the car.
While the potential to damage something exists in any kind of racing, the only real chance of breakage at the drag strip is at launch or radically missing a shift on a manual up track. Even then, most stock cars on stock tires aren't going to be blowing anything up on normal launches. Add in some sticky drag tires, or someone who doesn't know what they are doing (clutch drop at 6k
) and the risk of damage goes up.
On the Auto-x or road course, you are using every system of the car and pushing it to it's limits. It's not uncommon to burn through a set of brakes and tires in a weekend if you are doing anything more than just going out for a drive. Also running the car at WOT and through the first 4 gears for say 12 seconds isn't nearly as punishing as running for 1:30+ on a road course across the RPM range with constant down and up shifting.
Throw in the much higher chance of losing control on a road course and doing major body damage or worse and it's even more of a slam dunk for drag racing.
