The Esperante is a sports car made by Panoz, an American car manufacturer.

There are several models of the Esperante: the base model, the GT, the GTLM, the GTS, and the JRD (an aftermarket upgrade brand similar to Roush Mustangs). Each model has different specifications. The GTLM, for example, uses a supercharger to boost power from 305 hp (227 kW) to 420 hp (310 kW), raising performance from 0-62 mph in 5 seconds to 4 seconds. The GTS on the other hand is built as a driver's class spec car, to SCCA standards, with harness, roll cage, side bars, etc. Additionally, it is ~ 600 lb (270 kg) lighter than the base Esperante, has a steel 5.8 liter V8 racing engine that produces 385 bhp (287 kW; 390 PS), and is made of easily replaceable panels to facilitate small impact race repair. It can do 0-60 mph in 4.2 seconds, go up to a top speed of 182 mph (293 km/h), and achieve 0.98 g of lateral grip.

Panoz's engines are sourced from The Ford Motor Company's Modular V8 family. If this were a Ford it would be slotted between the Mustang sports car and the GT supercar; just like how the Corvette is slotted in Chevrolet's lineup between the Camaro and the ZR1.

A racing version of the Esperante known as the Esperante GT-LM was developed by Panoz for the GT2 category of the 24 Hours of Le Mans. 2006 was a year of noticeable achievement for Panoz.

The #50 Multimatic Motorsports Team Panoz Esperante GT-LM took a first place podium finish at the 55th Annual Mobil 1 Twelve Hours of Sebring beating GT2 regulars BMW, Porsche, Ferrari, and Spyker

That June the #81 Panoz Esperante GT-LM campaigned by England based Team LNT [1] managed to outlast and overtake the remaining LMGT2 contenders in the final hour of the 2006 24 Hours of Le Mans.

In Europe, Team LNT will be campaigning two Esperantes also. They will be competing in the British GT Championship and Le Mans Endurance Series. Team LNT will be returning to the 24 Hours of Le Mans in 2007 with both the #81 and #82 cars.[2]

During the 2007 American Le Mans season the Panoz Esperante GTLM will be managed, stateside, by Tom Milner and Team PTG. They will be campaigning two GT-LMs (#20 and #21). Team PTG scored 1 GT2 class podium in the hands of Bill Auberlen and Joey Hand in 2007 Sports Car Challenge of St. Petersburg. In the same year, Panoz Esperante GTLM also fielded Robertson Racing Team as 2007 ALMS season part-time entries in the hands of Andrea Robertson, David Robertson and Arie Luyendyk Jr.

2015 season will see 2009-spec Panoz Esperante GTLM's first participation in Super GT GT300 class and badged as Panoz Esperante GT300.
