Lingenfelter Performance Engineering (LPE) is an American automotive engineering company specializing in high performance automobile modifications, specifically engines and induction systems. Headquartered in Brighton, Michigan the company was founded by and named for NHRA driver John Lingenfelter. Over the decades since its founding LPE has created high performance versions of many GM vehicles such as the F-Bodies (Camaro, Firebird), B Bodies (Impala SS, Caprice, Roadmaster, Fleetwood), Corvette, CTS-V, GTO, Silverado, Suburban, Tahoe, Escalade, Denali, SSR, Hummer H2, and Sierra. Further it has also created performance enhancement packages for the Dodge Viper and Plymouth Prowler.
In January 1998 Motor Trend tested a Chevrolet Tahoe modified and tuned by Lingenfelter, powered by a 396 (6.5L) cubic inch Chevrolet V8 and achieved a 5.1 second 0-60 time as well as a 0.9g lateral acceleration figure. The heavy three row SUV completed the quarter mile in 13.8 seconds at 96 mph. These numbers matched the performance figures of a base model C4 Corvette and GMC Syclones/Typhoons of that era. This Tahoe was rated at 500 hp and a matching 500 pound-feet of torque. It utilized a 4WD drivetrain with 335/35ZR17 sized tires on all four corners. Motor Trend also tested a LPE-built Impala SS that had the same performance numbers as the last generation M5 (0-60 4.7 sec) due to its bored and stroked LT-1 (Displacement rose to 383 in3 and horsepower rose to 425). Another LPE vehicle was featured in the June 1996 issue of Car and Driver: a special C4 Corvette with a 427.6 in3 engine that attained a top speed of 212 mph. LPE's 2001 Corvette 427 twin-turbo with 800 Rear-Wheel horse power accomplished a 0-60 mph acceleration in 1.97 seconds.  Another LPE vehicle that the company developed and marketed to customers which has been one of their most powerful vehicles offered to date was a 2006 twin-turbo Corvette Z06 with 1,109 rear wheel horsepower.
