Models
The two initial models, introduced in 1968 and sold through 1977, were the 2.5 L 2500 and 2.8 L 2800. The airy, large greenhouse design was roomier than BMW's existing range and appeared rather large overall, in spite of being no more than 1 cm longer than Mercedes' midrange sedans, which were generally considered to compete in a lower class than the new E3.[4] They were large six-cylinder cars with fully independent suspension and four wheel disc brakes that handled well and impressed contemporary reviewers. Road & Track called the later Bavaria "delightful" and "superb", concluding that it was "one of the world's best buys". Aside from the larger engine, the 2800 also had bigger tyres and a somewhat sportier suspension, as well as various creature comforts such as a heated rear window, a full tool set, Boge Nivomat self-levelling rear suspension, and a smattering more external chrome.[7] The dual-carbureted 3-litre 3.0 S was introduced in 1971, being a more powerful and expensive model than the 2800; a fuel-injected version was also made. Also produced were long-wheelbase L models (3.0L, 3.3Li, etc.), whose sharp handling was a stark contrast to the large Mercedes-Benz models of the time. Langley Motors in Thames Ditton UK also produced an estate (tourer) version. Surprisingly, considering their respective marketing profiles, the 3.0 Si sedan was faster than the 3.0 coupé; which was a heavier car by 50 kg, with the same drivetrain.
In the UK, some 3-litre cars were used by the police in the 1970s, with the infamous ad "It takes one to catch one".[8][9] Thames Valley Police bought a 3.0 Si in 1972, followed by Derbyshire Constabulary the same year and the West Mercia Police in 1974.[10] The West Mercia Police's car was in an unusual livery called "truck yellow".[11] Following the success of the 3.0 Si, many police forces in the UK began purchasing BMW cars, next one being the 5 Series (E12) in late 1970s.[10]
The body was surprisingly light for its size, weighing less than the smaller E9 coupé. Vision is also good, with narrow pillars and no less than 2.5 m2 of overall glass area.[2]
At the end of 1973 the new, larger 3.3 L was presented, going on sale in January 1974. It had the longer wheelbase and a bigger engine, although the power was no more than that of the 3.0 Si. Instead, more torque meant to provide a more luxurious rather than BMW's usual sporting feel. This engine was updated to fuel injection in June 1975, with a few more horsepower. Subsequent to the introduction of a 3.2 liter version of this engine in the 1976 BMW 633CSi, this slightly smaller model found its way into the 3.3 Li as well. The E3 Sedan was in production from 1968–1978, with a total of circa 190,000 cars produced. Of these, 71,804 were of the US-only "Bavaria" model.
North America
In the US market, the 2500 and 2800 were introduced in 1969. The 2500 was shy of many of the luxury features included in the 2800, and with the smaller engine, it sold for about $5,600 in 1970-equal to $ today.[12] The 2800 offered full leather interior, power windows, and power sunroof, which its price of $6,874 ($ today) reflected. For the 1971 model year Max Hoffman, the BMW importer for the USA, convinced BMW AG to build the 2500 configuration car but use the 2800 engine — offering more power without the weight and expense of the 2800's luxury features. This new E3 configuration was called the "Bavaria" and was unique to the US market. Priced at about US$6,000 ($ today), the Bavaria came to replace both older models. It is generally considered the forebear of the modern BMW high-performance large luxury sedan as it combined brisk acceleration, sporty handling, plenty of room for four people and a large trunk. An optional three-speed automatic transmission was offered.
For the 1972 model year, the 2500 was dropped while the M30 engine size in the Bavaria was increased to 3.0 liters. The former 2800 was then called the 3.0 S reflecting the 3.0 liter engine. These two models, the 3.0 S and the Bavaria, made up the North American E3 sedan line-up for 1972 through 1974. For the 1974 model year the E3 received the ungainly, federally mandated 5 mph bumpers front and rear, significantly altering its profile. In 1975 BMW introduced fuel injection to the US market M30 motor, replacing the twin two-barrel Zenith carburetors used since its inception. The Bavaria was dropped from the line-up, nominally replaced by the fuel-injected M30 powered E12 530i, and the fuel-injected 3.0 Si became the highest end of the BMW model range. The fully optioned 3.0 Si was sold during the 1975 and 1976 model years.
