using twin Zenith 35/40 INAT carburetors) 3.0Si, 3.0Li, 3.0CSi (2985 cc, 200 or , depending whether Bosch D-Jetronic or L-Jetronic was installed) 3.3L, 3.3Li (3295 cc, ) 3.3Li (3210 cc, 1976-1977) 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 design was roomier than BMW's existing range and appeared rather large, in spite of being no more than longer than Mercedes' midrange sedans, which were generally considered to compete in a lower class than the new E3. They were large six-cylinder cars 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. The big-bore, dual-carbureted 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. With a fully independent suspension along with four wheel disc brakes, the E3 was well ahead of its time in the early 1970s. 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. 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 of overall glass area. 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
