BMW 3 Series (E30)

The  BMW E30  is the second generation of  BMW 3 Series , which was produced from 1982 to 1994. The initial models used the  coupe  (two-door sedan) body style, with four-door  sedan  models introduced in 1983,  convertibles  introduced in 1985 and  wagon/estate  models (marketed as "Touring") introduced in 1987. The E30 was the first 3 Series to be available in wagon and four-door sedan body styles. It was also the first 3 Series to have a diesel engine option.  All-wheel drive  was introduced to the 3 Series range with the 325iX model. The  BMW Z1  roadster was based on the E30 platform. The  E36  replaced the E30 coupe models in 1990. Sedan production concluded on April 30, 1991 at Regensburg, with a white example. Other variants were phased out gradually, until the final E30 model, a Touring, was produced in 1994. [6] The first  BMW M3  was built on the E30 platform. The E30 M3 is powered by the high-revving  BMW S14  four-cylinder petrol engine, which

V16 ENGINE

V16 ENGINE A  V16 engine  is a  V engine  with 16  cylinders . Engines of this number of cylinders are uncommon in automotive use. A V16 engine is perfectly balanced, so long as its constituent  straight 8  banks are balanced, regardless of the V angle. That is to say, it does not require contra-rotating  balancing shafts  which are necessary to balance engines with odd numbers of cylinders in-line or those equipped with counterweighted crankshafts like the 90°  V8 . In addition V angles of 45° and 135° give an impulse every 45°, so are optimal solutions, for  even-firing  and non-split bearing  crankshaft   journals . V16 engines are rarely used in automobiles because V8s or  V12s  of the same  displacement  typically produce just as much power, and are much less expensive to manufacture and maintain. The few V16s that have been produced were used in high-end luxury and high-performance  automobiles  due to their smoothness (low vibration). Today, the most common app
