A list of 10 incredible six-cylinder engines

TopFutureCars

Because straight-sixes are longer than V8s of the same capacity, they are more difficult to package, which limits the layout’s prevalence. Having just one bank of cylinders makes them technically straightforward.

Famously, when they run, they have a silky smoothness and a natural equilibrium. Furthermore, their music is just beautiful. Who among us hasn’t been moved by the glorious roar of a straight-six engine in an antique car? Here are 15 of the top ones for your viewing pleasure.

Spyker 60hp

Jacobus and Hendrik-Jan Spijker, two Dutch brothers, are credited with creating the first straight-six engine in 1903 for their 60hp racing vehicle. The four-wheel brakes and four-wheel drive of this remarkable vehicle were among their many innovations. The automobile was built to take part in the fatal 1903 Paris-Madrid race. Unfortunately (or maybe luckily), the Spyker wasn’t ready in time. Almost immediately after Spyker, the British manufacturer Napier produced its own straight-six model in 1904.

Although the term “Silver Ghost” initially referred to a specific Rolls-Royce 40/50hp with the registration number AX 201, it is now often used to refer to all instances of that type. The Silver Ghost debuted in 1906 and has always been available with a straight-six engine whose displacement ranged from 7.0 to 7.4 liters. AX 201 was determined to be almost 100% dependable over hundreds of kilometers of testing, and its engine was very quiet for its day.

The 40CV was manufactured by Renault from 1911 to 1928, first with a 7.5-liter straight-six engine and then with a 9.1-liter engine, making it one of the company’s several high-end automobiles before World War Two. The 40CV won the Rallye Monte-Carlo Rally in 1925 despite being constructed with elegance and refinement. A one-seater variant of it averaged 108 mph for 24 hours the next year, setting a new world record.

AMC

In 1964, American Motors Corporation upgraded the performance of the Typhoon edition of the Rambler Classic with a new straight-six engine. Chrysler was pleased to continue developing what was by then a pretty ancient engine after acquiring AMC 22 years later. The AMC straight-six, which has been around since 1966 and has been called “as dependable as a block of wood,” was still in use as recently as 2006. It was utilized in the 4.0-liter version in various cars, including the second-generation Jeep Cherokee (pictured).

Tadek WO Bentley’s original engine design for the Lagonda was replaced by Marek’s straight-six. The DBR2 racing vehicle was the first to employ the Marek’six,’ which was later incorporated into the DB4, the DB5 (renowned for its appearances in James Bond movies), the DB6, and the DBS. The’six,’ with displacements between 3.7 and 4.2 liters, was succeeded by a V8 engine, also developed by Marek.

The Big Healey used the most powerful version of BMC’s C-series straight-six engine, which displaced 2.9 liters. Morris created this unit, which debuted in 1954, five years before Healey produced their 3000 series. It was standard on several models of the Austin Westminster and other BMC cars. The Healey was the only vehicle with a C-series engine to win races and rallies at the highest levels internationally.

The BMC E-Series

The E-series was offered with a variety of engine displacements, including a 1.5- or 1.7-liter four-cylinder and a 2.2- or 2.6-liter straight-six. The’six’ was used in a wide range of cars manufactured and sold in Australia and South Africa, as well as the Austin 1800 and later Princess (shown) produced in the United Kingdom, and other similar models sold under various badges. The Ambassador eventually replaced the Princess and was the only model available with the newer O-series four-cylinder engine.

The dohc M88 unit was introduced in 1978, however BMW had a long history of producing straight-six engines before to that. The M1 was the first BMW with a mid-mounted engine, and it was the only one BMW ever constructed (the other being the i8 hybrid). The first-generation M5, which was likewise powered by the M88, had impressive performance despite its understated exterior. Group 5 racing vehicles utilized the turbo version, while the 6 Series coupe and 7 Series luxury sedan also featured variations on the theme.

BMW M3 CSL

An very high-performance and pricey variant of the third-generation (E46) M3, the CSL had extremely low manufacturing numbers. The 3.2-liter straight-six engine was used in other M3s from the same period and in high-performance Z3 and Z4 sports cars, so it was not unfamiliar. BMW changed the camshafts and redesigned the intake and exhaust manifolds for the CSL. The previous 340HP (variable) power output is now about 360HP.

Bristol

The Bristol Aeroplane Company used a tuned version of the 1971 cc BMW M328 straight-six that debuted in 1936 in their first luxury vehicle, the 1947 400. This was the performance version of BMW’s first straight-six engine, the M78 from 1933. After expanding it to 2.2 liters, Bristol kept using it until 1961, when they finally switched to Chrysler V8s. Furthermore, the business provided the unit to Frazer Nash and AC for use in their road vehicles, as well as Cooper for use in its 1952 Formula Two racer.
