The 2018 Chevrolet Tahoe RST pairs a 420-horsepower, 460-lb-ft 6.2-liter V8 with a 10-speed automatic shared with the Camaro ZL1, hitting 60 mph in a claimed 5.7 seconds while still towing up to 8,300 pounds. Choosing that engine also unlocks Magnetic Ride Control, plus optional Borla exhaust and Brembo brakes. It’s proof Chevy is willing to loan its performance parts bin to the family truck.
A hidden VIN code separates GM’s last true first-generation small block from any other 350, and most owners never learn where to look for it. The Vortec 5700 L31 quietly powered Escalades, Suburbans, and full-size trucks through the late 1990s, while its oversized cousin, the 400 cubic inch small block, carried its own quirks and a notorious overheating flaw. Read on to find out what separates these two small blocks from the rest of the Chevy family, and why one of them is still available brand new today.
Hennessey Performance’s 800-horsepower Cadillac Escalade HPE800 lines up against a completely stock 2018 Camaro ZL1 1LE, and the family SUV jumps out front before the Camaro claws back ground at the top end. Viewers immediately drew comparisons to the legendary 1991 GMC Syclone that once embarrassed a Ferrari, and debated whether the ZL1’s manual transmission cost it the race. Watch to see just how close a stock sports car can stay against 200 extra horsepower wrapped in three rows of leather seats.
