GMC Sierra (2019) 6.2L V8 EcoTec3 426 hp — mass-market petrol engine of the passenger segment of the General Motors group (США, 1911). A modern petrol engine built in 2019 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
GMC specialises in premium pickups (Sierra) and large SUVs (Yukon, Hummer EV). GMC shares platforms and engines with Chevrolet within GM. GMC is an American pickup and SUV brand, part of General Motors since 1909. Chevrolet 2.0 / 1.4 Turbo are mainstream turbo engines for saloons and compacts. GM ECUs (E78/E80/E92) are Bosch-based but use their own checksum. Camaro SS / ZL1 / Corvette offer significant potential with hardware.
The US Chevrolet community is the largest for Camaro, Corvette and LS-swaps. Camaro/Corvette confidently reach Stage 2 with hardware. LS-swap is an industry of its own (Chevy LS engines into any car). Top Chevrolet Corvette / Camaro ZL1 engines sit at the power ceiling of the American performance segment. HP Tuners is the leading tool for top Chevrolet models.
