BMW 525i M20 I6 engine
The 525i was built throughout the E34 production, and in 1992 was offered as a wagon (touring version) in the USA. In June 1990 (1991MY), the engine was switched from the single overhead cam M20 engine to the double overhead cam M50B25 engine, raising power from 170 to 192 horsepower (141 kW - US Specifications were: 168 to 189 hp gain.) Also, fuel economy improved by ten percent, and a change from a timing belt to a timing chain improved reliability. A further revision of the 525i engine took place in 1993, when VANOS was added to the M50 engine which was designated the M50TU. The TU represents a Technical Update, reflecting the variable valve timing technology (VANOS) added to the intake camshaft. VANOS brought no horsepower increase, but flattened the torque curve from about 3,000 rpm up to redline at approximately 6,300 rpm. Torque on the US Vanos Engine was raised from 181 ft-lb to 184 ft-lb. 0-60 mph times with automatic transmission dropped to 9.1 sec. vs. 10.0 from the Non-VANOS equipped M50 motor - a significant improvement. M50 engine was the most popular variant sold in NA[citation needed]. The 525i was also the most popular E34 model globally - close to 250,000 units were produced.
