Clearly this has to do with the break-in period.
After about 3,000 miles my VT was significantly faster than it was when new.
If you do the math, a 200hp 2,800lb car is going to do 0-60 in the mid 6 second range. Most of the car magazines scratched their heads when the VT did 0-60 in the mid 7 second range. But they are not used to testing cars that have a 100,000 mile warranty.
Don't forget that the BRZ/FR-S turned in slower 0-60 times than the VT did. Those cars should be somewhat faster than the VT - and doing mid 6 second times as well.
