google er din venn: An economy version called the 325e (the e stands for the Greek letter eta, signifying efficiency) was released as a lower revving, more fuel efficient engine. To maximise low-rev torque, the engine was the largest available in the chassis (aside from the rare South African version which was available with the 3.3 L M30). The 2.7 L had a longer stroke than the 2.5 L, with a more restrictive head, four cam bearings instead of seven (less internal friction), and softer valve springs. This resulted in 90 kW (122 PS; 121 hp) at 4250 rpm and, more importantly, 240 N·m (180 lb·ft) at 3250 rpm (peak torque for a 325i is 215 N·m (159 lb·ft) at 4000 rpm).
Kort forklart en Økonomi/miljømotor.
