We are now in 2020 and GM is offering a new in-line six diesel engine option to power its pickups. This all new 3.0L turbocharged diesel engine (RPO – LM2) is designed to achieve high fuel economy while still delivering the horsepower and torque truck buyers demand. This is the first time ever that GM has offered an inline diesel for its light duty trucks. The engine itself is constructed of mainly aluminum components to reduce weight for fuel economy.
