6. BMW 524td (E28)
BMW’s venture into diesel territory began with the distinctive 524td (E28), a sedan that combined sporty handling with diesel practicality.
Powered by a robust turbocharged inline-six engine, it was surprisingly spirited, delivering ample torque and impressive fuel economy.
However, the 524td’s performance was accompanied by an unmistakably loud diesel clatter, a sound uncommon in BMW’s typically refined lineup.
Owners frequently praised the sedan’s durability, with many examples effortlessly surpassing 250,000 miles without significant engine work.
Today, this early diesel BMW remains a beloved classic, valued for its blend of longevity, characterful engine noise, and dependable German engineering.
