BMW 320/323i (E21): A Comprehensive Overview
Introduction
Introduced in 1975, the BMW 320/323i (E21) marked a significant departure from its predecessor, the New Class (Neue Klasse). With its focus on performance, handling, and efficiency, the E21 established itself as a benchmark in the compact sports sedan segment.
Design and Styling
The E21's exterior is characterized by its sleek and aerodynamic profile. The iconic "Hofmeister kink" at the C-pillars provides a distinctive visual signature. The angular body lines and flared wheel arches exude a sense of sporty aggression.
Interior
The E21's interior is designed with a driver-centric focus. The dashboard is ergonomically laid out, with clear gauges and intuitive controls. The comfortable and supportive seats provide excellent support, even during spirited driving.
Powertrain and Performance
The E21 was initially available with two engine options: the 2.0-liter M10 inline-four in the 320i and the 2.3-liter M20 inline-six in the 323i. These engines delivered impressive power and torque, propelling the car from 0-60 mph in under 9 seconds.
The E21's handling was renowned for its precision and responsiveness. The front-mounted McPherson strut suspension and rear semi-trailing arm suspension provided excellent stability and cornering capabilities.
Transmission
The E21 was offered with a choice of manual or automatic transmissions. The manual transmissions were known for their smooth shifting and precise gear selection, while the automatic transmissions provided seamless gear changes for a comfortable driving experience.
Braking System
The E21 featured a four-wheel disc brake system that provided excellent stopping power and fade resistance. The ventilated front discs were particularly effective in dissipating heat during heavy braking.
Suspension
The E21's suspension system comprised McPherson struts at the front and semi-trailing arms at the rear. The suspension was tuned to provide a balance between handling and ride comfort. The car's low center of gravity contributed to its impressive cornering capabilities.
