Nope, I just don't trust them. They somehow manage to get good times from European cars but when it comes to Japanese or American, they are far behind. I just don't understand how there can be such a discrepancy when it comes to results. This is my opinion, so you can take it however you like.
I honestly believe the factory test drivers more because they know how to absolutely bring the the TRUE potential of the car. I want to know what the car can TRULY do, not what it can do in the hands of just some guy.
and I have a problem with factory times since you have no idea if its a pre-production car or if the car will be exactly like this when it reach the open market. You can use factory times but when you want to compare with other cars , its just pointless. Different driver, different skill.
Sportauto is the best when you want to compare times with other cars, since they use the same driver.
and another thing about Sportauto, they rarely get down to factory times with german cars either. BMW says M5 did it 7.52 min, Sportauto wasn't even close. Like I said , sportauto did 7.49 min with Corvette Z06 and thats faster than many Porsches and faster than any BMW. Sportauto did 7.48 min with 997 GT3 RS which was on R-tires and its only 1 second faster than Z06 which wasnt on R-tires. Thats darn impressive time by Zo6 done by Sportauto. I'm not buying your arguments.
Pretty pointless to argue further about it , since Sportauto is well-respected magazine around the world and their laptimes are used worldwide.
EDIT: Its intresting you mention japanese cars since there havent been many sportscars the last years for sale in Germany that comes from Japan. If they arent for sale in Germany then Sportauto can't test them. If you check the Sportauto N-ring list there arent many japanese cars. The fastest japanese car they tried is Honda NSX-R and it did it in 8.09 min and this with "only" 280 hp. This is a great achievement and its done by Sportauto.
Neither Toyota Supra/or previous generation Skylines was tested by Sportauto. So its very intresting you say japanese cars are far behind, LoL, of course they are since there havent been many powerful japanese cars for sale in Germany the last years. I certainly hope you didnt expect European versions of Impreza or EVO being under 8 minutes. NarutoRamen, your theories about Japanese cars fail - big time
Nissan GTR and Corvette Zr1 will be for sale in Europe so in a near future you will see Sportauto trying them and the times wont be bad. Of course it wont be near factory times but Sportauto rarely are, so no biggies here.
