Chronology
Predecessor BMW M20
Successor BMW M50

The BMW M30 is a SOHC straight-six petrol engine which was produced from 1968 to 1995. With a production run of 27 years, it is BMW's longest produced engine and was used in many car models.

Contents

The first models to use the M30 engine were the BMW 2500 and 2800 sedans. The initial M30 models were produced in displacements of 2.5 litres (2,494 cc) and 2.8 litres (2,788 cc). Larger displacement versions were introduced over time, with the largest version being 3,430 cc (209.3 cu in), which was sometimes badged as "3.5 litres". [1] As per the BMW M10 four-cylinder engine from which the M30 was developed, the M30 has an iron block, an aluminium head and an overhead camshaft with two valves per cylinder.

The engine was given the nicknames of 'Big Six' and 'Senior Six', following the introduction of the smaller BMW M20 straight-six engine in the late 1970s. The M30 was produced alongside the M20 throughout the M20's production, and prior to the introduction of the BMW M70 V12 engine in 1987, the M30 was BMW's most powerful and largest regular production engine.

Following the introduction of the BMW M50 engine in 1990, the M30 began to be phased out.

Ward's have rated the M30 as one of the "Top Engines of the 20th Century". [2]

Design

The M30 was originally developed in the late 1960s, loosely based on the BMW M10 four-cylinder engine first used in the BMW New Class sedans and coupes. [3] :70 Initially, the engine code was "M06" and the "M68", until all versions began to use the "M30" prefix in 1981. [4] [5] [6]

Common features between the M10 and M30 include a profile lowering 30-degree slant to the right, a crossflow cylinder head (a gas flow head in later designs[ citation needed ]) and chain-driven camshaft with rocker arm valve actuation. [7] Further similarities include a cast-iron block with an aluminium head and a forged crankshaft. The first two M30 engines introduced were the 2.5 L (2,494 cc) and the 2.8 L (2,788 cc) versions, which both used an 86 mm (3.39 in) bore. [3]

M30B35LE/M90 engine

The M30B35LE engine, also called the M90, was used in several models from 1979-1982. It combines the block from the motorsports BMW M88 DOHC engine with the M30's SOHC cylinder head.

The first 2,494 cc (152.2 cu in) version of the M30 was introduced in the 1968 E3 2500. This version uses dual Solex Zenith 35/40 INAT carburettors, has a compression ratio of 9.0:1 and produces 110 kW (150 PS; 148 bhp) in most applications. [8] It has a bore of 86 mm (3.39 in) and a stroke of 71.6 mm (2.82 in).

The M30B25 has previously been called the M06 and M68, prior to BMW retroactively renaming it the M30B25V (V for Vergaser- carburettor in German). [9]

Applications:

M30B25

In 1981, Bosch L-Jetronic electronic fuel injection was added to the 2,494 cc (152.2 cu in) version. Peak power remained unchanged at 110 kW (148 bhp), however torque increased slightly to 215 N⋅m (159 lb⋅ft).

Applications:

M30B28V

In its original form, the carburetted 2.8 used two Solex Zenith "35/40 INAT" carburetors, the compression ratio is 9.0:1 and the engine produces 125 kW (170 PS; 168 hp) and 235 N⋅m (174 lb⋅ft). [3] :77 The specifications went on to vary depending on the model year, carburettor and country. The bore is 86 mm (3.39 in) and the stroke is 80 mm (3.15 in).

This version has also been known as the M06 and M68, prior to BMW renaming it the M30B28V.

Applications:

M30B28

In 1977, Bosch L-Jetronic electronic fuel injection was added to the 2,788 cc (170.1 cu in) version. [15] Power increased to 135 kW (181 bhp) and torque increased to 240 N⋅m (177 lb⋅ft).

M30B30V

Based on the M30B28V version with a 3 mm (0.12 in) larger bore, the M30B30V produces 132 kW (180 PS; 178 bhp) and 255 N⋅m (188 lb⋅ft), [26] [27] uses dual Zenith 35/40 INAT carburettors and has a compression ratio of 9.0:1. In United States trim, this engine produced 127 kW (170 hp) at 5800 rpm. [28]

Applications:

M30B30

The fuel injected version of the 2,986 cc (182.2 cu in) M30 debuted in 1971 in the E9 3.0 CSi and initially used the Bosch D-Jetronic mechanical fuel injection system. [31] In 1976, the fuel injection system was upgraded to Bosch L-Jetronic electronic fuel injection. [31] The M30B30 produces up to 147 kW (200 PS; 197 bhp) and 272 N⋅m (200 lb⋅ft), [32] depending on the model year and whether a catalytic converter is fitted. The compression ratio is 9.2:1. With catalytic converter, compression ratio is 9:1.

Applications:

M30B32

Despite having a capacity of 3,210 cc (195.9 cu in), this engine appeared in many cars badged so as to suggest 3.3 L (201 cu in) of displacement- such as the 633i, 3.3 Li, and 733i. The compression ratio is 8.8:1. In the E24 633CSi coupe, the M30B32 uses Bosch L-Jetronic electronic fuel injection. [15] The US version used L-Jetronic from 1978 until mid-1981, changing over to Motronic digital fuel injection in June of that year. The 1979 732i is BMW's first use of Bosch's Motronic fuel injection. [38] The bore is 89 mm (3.50 in) and the stroke is 86 mm (3.39 in).

Applications:

M30B33V

The carburetted M30B33 produces 140 kW (190 PS; 187 bhp) and 289 N⋅m (213 lb⋅ft). [43] [44] It has a bore of 89 mm (3.50 in) and a stroke of 88 mm (3.46 in).

Applications:

M30B34

The M30B34 engines sold in Europe and most other markets used a 10.0:1 compression ratio and produced 160 kW (218 PS; 215 hp). [46] In North America and Japan, the M30B34 used an 8.0:1 compression ratio and produced 136 kW (185 PS; 182 hp). [47] This engine was also offered in Europe from the latter half of 1985 until mid-1987. [15] :238 In all markets, the Bosch Motronic digital fuel injection system was used. The bore is 92 mm (3.62 in) and the stroke is 86 mm (3.39 in).

Applications:

M30B35

M30B35 Bmw-m30b35-right.jpg
M30B35

This engine has a capacity of 3,430 cc (209.3 cu in), despite the "B35" model code. It produces 155 kW (211 PS; 208 hp) at 5700 rpm and 305 N⋅m (225 lb⋅ft) at 4000 rpm, has a compression ratio of 9.0:1 and uses Bosch Motronic 1.3 digital fuel injection. [15] It was also offered without a catalytic converter for certain markets; this version produces 162 kW (220 PS; 217 hp) and 315 N⋅m (232 lb⋅ft) at the same engine speeds. [48]

Applications:

Turbocharging

The M30 was the basis for the turbocharged M102 and M106 engines.

The Alpina B10 Biturbo used a modified version of the M30, with two turbochargers and forged pistons. Producing 265 kW (360 PS; 355 bhp) at 6000 rpm and 520 N⋅m (384 lb⋅ft) at 4000 rpm, the engine made this car the fastest sedan in the world. The final 50 M30 blocks were shipped to Alpina for use in the final 50 B10 Biturbos. [51]

M102

The M102 was produced from 1980 to 1982. It was BMW's first turbocharged six-cylinder engine.

The M102 (also known as M30B32LAE) [52] has a displacement of 3,210 cc (195.9 cu in). [53] The KKK K27 turbocharger produces 9 psi (0.62 bar) of boost [54] and an air-to-air intercooler is used. [55] The compression ratio is 7.0:1. [54]

The M102 produces 188 kW (256 PS; 252 bhp) [56] and was used in the E23 7 Series, in the model was designated "745i". [56] The M102 was not available in right-hand drive cars, leading to the South African 745i using the BMW M88 naturally aspirated DOHC straight-six engine instead.

Applications:

M106

The M106 (also called M30B34MAE) replaced the M102 and was produced from 1982 to 1986.

Some of the M106's upgrades over its predecessor are a result of the M30B34 version of the M30, which was also released in 1982. These upgrades include Bosch Motronic engine management and an increased displacement to 3,430 cc (209.3 cu in). The compression ratio was increased from 7.0:1 to 8.0:1. [55] [57]

Peak power output is the same 185 kW (252 PS; 248 bhp) as the M102, [58] however it occurs at lower RPM [57] and peak boost is reduced from 9 to 6 psi (0.62 to 0.41 bar). [59]

There was no direct successor to the M106, however BMW's next turbocharged petrol engine was the BMW N54, introduced in 2006.

The M30 powered a series of E9 CSL and E24 6 Series coupes to European Touring Car Championship (ETCC) throughout the 1970s and into the middle 1980s, even though a more powerful DOHC 24-valve head had been developed for high-performance motorsports and street use.

The BMW M88 high-performance engine is based on the M30 block. [60]
