So who do we trust? Motortrend or Car and Driver? Nothing sounds right about the Motortrend stats. 70 to 0 in less than 120 feet, that's like Enzo stats there. Having driven both cars, I can say that the GenCoupe's handling capabilities fall far short of an XF. They are heavier, far less rigid, and designed for teen pan-heads who get their rocks off going sideways. They also lose to us on the top-end for 3 reasons. 1. We keep almost all of our power across our whole rpm range. 2. Gearing. 3. Aerodynamics, especially on the underside of the car. Having been underneath both, I see that the XF has panneling over everything but the drive-shaft and exhaust area. The Gen doesn't and where as the XF feels like I'm going 30mph at 150mph, the Gen starts shaking at 140, violently at 150, death likely occurring by 160 or 170. As for the 3.7 I'm interested in hearing more about it, such as the difficulty of the swap, what else is involved in making it work, and boostability. Hopefully its not in the same boat as the 320. I still intend to finish my attempt to get stock SRT levels from and N/A because its a project I committed to try all the way through and also because the best part is that all the mods I'm doing will swap to a 37, 43, 50, or 55. As for a higher differential, I wouldn't do that even if I could because I want a well rounded car, I don't want to throw away my top end so that I can go in a straight line over and over.
