The engine is a hand-built version of Ford's all-aluminum 4.6-liter DOHC V8. Rated at 320 horsepower and 317 pound-feet of torque, this V8 maintains a smooth, flat power curve right on through to the redline. It's not as torque-rich down low as most eight-cylinders, but coupled with the Esperante's lightweight chassis it provides more than ample thrust at any speed.
The transmission is a five-speed manual topped with one of the sturdiest, most precise shifters we've had our hands on in a long time. One editor likened it to the bolt action of a well-oiled rifle, a sentiment that rang true every time we snapped off another tire-chirping shift. The clutch is more subtle in its action, with a smooth progressive feel and an absence of heft that belies the fact that it never falters when it comes to laying down the power.
Since the company's inception, Panoz has been a dedicated proponent of aluminum construction for its ability to provide the stiffness of steel with less weight. The Esperante's aluminum body is made using a process known as superplastic forming that was originally developed for the aerospace industry. Underneath, an all-aluminum spaceframe serves as the car's backbone while a carbon-fiber substructure connects the body to the frame.
With a curb weight of 3,279 pounds, the Esperante is comparatively svelte next to Mercedes' SL and Jaguar's XK, both of which tip the scales at over 4,000 pounds. This no doubt contributes to the Esperante's more visceral feel on the road and quicker numbers at the track. The all-aluminum structure also manages to retain a suitable level of rigidity despite its roofless configuration. Cowl shake is minimal, and aggressive driving that would leave the XK floundering does little to tweak the Esperante's rock-solid framework.
A fully independent, double-wishbone suspension provides the connection between the chassis and the road along with coil over shocks and four-wheel disc brakes. Aided by our test car's optional 18-inch wheels and tires and perfect 50/50 weight distribution, the Esperante exhibited tenacious grip and an easily manageable feel at the limit. Body roll was nearly imperceptible and midcorner bumps were handled without a hiccup.
