Default oil overheating unique to vq37vhr engine?

I was reading the latest edition of Dsport magazine where they reviewed several RWD cars. Predictably they criticized the 370z for the engine overheating its oil and shutting down after 2-3 laps on the track. They mentioned that the Genesis Coupe doesn't have this problem. This got me thinking, are there any other cars out there with a similar overheating problem other than the 370z and g37?

I know bmw's turbocharged 335i also overheats easily, but other than that, what else? Gen Coupe, Corvette, Viper, Mustang, Camaro, Cayman and 911, M3, M5, Lotus Elise/Exige, Miata, Rx 8, ferrari, lamborghini, aston martin, turbocharged cars like the STi, Evo, and even Nissan's own GT-R do not overheat and go into limp mode after 3 laps on the track. As far as I know most, if not all, of these cars do not have an oil cooler from the factory.

So the question is why do they not overheat and shut down like our cars on the track? Is it that they do not produce much heat? If so what is so different about our engines that make them overheat so much? If these cars do heat up their oil so much, why do they not go into limp mode? Are their engines not as vulnerable to hot oil as our engines? If so why? Why would the vq37vhr engine be unusually vulnerable to hot oil? Or is it simply the case that the oil in these cars does overheat like our cars and their engine also suffers excessive wear and tear as a result but the manufacturer just couldn't care to put a limp mode for engine protection.
