2008 Mosler MT900S — 2:45.9

The Mosler was just so astoundingly fast that, frankly, our amateur skills could not fully exploit its capabilities. But uncorking the 550-hp LS7 V-8 propels this featherweight like a cannon shot. That tremendous speed was in itself unnerving. There are subtle bumps on the gently curved start-finish straight that sent the rear end skipping to the point that we instinctively feathered the throttle. It cost us some time, so we pitted for a shock adjustment. When we went back out, a strip of wheel weights fell off, producing enough vibration that our deeply rooted instincts for self-preservation took over and we parked it. Overall, though, it’s a remarkably well-turned-out car. Warren Mosler’s years of work have paid off. It’s like a streetgoing IMSA prototype, and it’s even quicker than its chart-topping time suggests. Lap Test
