Chevrolet Malibu
2.5-liter Ecotec four with direct injection, 197 hp. The uncomplicated base alternative in the 8th-gen and early 9th-gen Malibu. A bit more durable than the 2.4 LE5 but still sensitive to stretched oil intervals. The last Malibu engine without a turbo and without the later 1.5T's LSPI problems.
The last Malibu with a normal engine
The 2.5 LKW was the port-of-call for anyone wanting an uncomplicated Malibu. No turbo, no direct-injection piston dramas, no LSPI lawsuits — just a naturally-aspirated Ecotec that wanted clean synthetic oil and short intervals. Gone after 2018. A footnote in Malibu history, and the last reasonable base engine the car ever had.
