Lotus has never built every engine it used, and that is half the fun of its road cars. The story of Lotus engines runs from a 75-hp Coventry Climax four in the 1957 Elite to a Toyota V6 in the 2009 Evora.
Along the way, Lotus borrowed blocks from Ford, Rover and Isuzu, and it designed its own fours and a twin-turbo V8. Here are nine Lotus engines in order, each with the car that carried it.
The figures come from Hagerty, Lotus itself, owners-club records and published model histories. Also, where sources give different numbers, we say whose number it is.
1. 1957 Coventry Climax FWE, the first of these Lotus engines
The Elite rode on a fiberglass monocoque made of three main pieces. For power, it used a Coventry Climax 1,216-cc four known as the FWE. As a result, that small engine made 75 hp on two SU carburetors.
According to Hagerty’s valuation guide, almost 1,200 Elites were built from 1957 to 1962. In fact, Hagerty’s listing for a 1961 car shows $61,100.
2. 1962 Lotus Twin Cam, Lotus Elan
Next, Lotus mixed its own parts with Ford’s. The result was the Twin Cam, which put a Lotus alloy double-overhead-cam head on Ford’s 1,558-cc Kent four. In particular, Lotus engineer Harry Mundy designed the crossflow head.
The first production version arrived in the 1962 Elan, with about 100 bhp in standard tune, Silodrome reports. Soon, the Lotus-Cortina and the Europa used it too. Later, the 1971 Big Valve version made about 126 bhp. Production finally ended in 1975.
3. 1972 Lotus 907, Jensen-Healey and Esprit S1
The Twin Cam’s replacement was the 907, an all-alloy four with twin overhead cams. In total, it displaced 1,973 cc. Oddly, it reached buyers first in a car that wasn’t a Lotus. That is, the 907-equipped Jensen-Healey went on sale in 1972.
Silodrome adds that Lotus’s own later Elite and Eclat used it, as did the Esprit wedge. According to Silodrome’s Esprit history, the Esprit Series 1 ran from 1976 to 1978. In European trim, its 907 made 160 hp at 6,580 rpm.
4. 1980 Lotus 910 turbo, Esprit Turbo
By 1980, Lotus had bolted a turbocharger onto the Esprit’s four. The Type 910 grew to 2,174 cc and used a Garrett AiResearch T3 turbo at about 8 psi of boost, Supercars.net records.
Silodrome gives its output as 210 hp at 6,250 rpm. It first went into the Essex Turbo Esprit in 1980. Then the later Turbo Esprit used the same engine. Motoring Research says the 210-hp car could top 150 mph.
5. 1989 Isuzu turbo, Lotus Elan
The second Elan took a new route among Lotus engines. For one thing, it was a front-wheel-drive Lotus, and its engine came from Isuzu in Japan rather than from Lotus or Ford.
Motoring Research lists the 1989 Elan 100 with a 160-hp turbocharged Isuzu engine. Moreover, it credits the front-driver with a brilliant chassis.
6. 1995 Rover K-series, Lotus Elise S1
The Elise made its public debut at the Frankfurt Motor Show on September 12, 1995. Underneath, it sat on a bonded, extruded aluminum chassis. At launch, a 1.8-liter, 118-bhp engine and a 5-speed gearbox powered it, Lotus says.
However, that engine came from Rover. The SELOC owners’ club notes that all S1 variants have Rover K-series engines, and it lists the base car at 118 bhp. Meanwhile, Lotus’s own tables count about 15,530 cars of all models from 1996 to 2003.
7. 1996 Lotus Type 918 V8, Esprit V8
For the Esprit’s last act, Lotus designed a V8 of its own. At first glance, the numbers were big: the Type 918 displaced 3,506 cc and breathed through twin Garrett AiResearch T25/60 turbochargers. Lotus announced it in 1996.
Even so, its rated output was 350 hp, according to Silodrome. However, the V8 had a short career. Esprit production ended in February 2004, and Silodrome counts just 10,675 Esprits built across all versions.
8. 2004 Toyota 2ZZ-GE, Lotus Elise 111R
In 2004, Lotus switched from Rover to Toyota power. SlashGear says the change began with the Elise 111R and its 1.8-liter 2ZZ-GE four.
The SELOC model list rates the 2004 111R at 189 bhp. It is also the earliest Toyota-engined Elise on that list. After that, Lotus used the same 2ZZ-GE in the 2004 Exige, then added a supercharger for the 2006 Exige S, SlashGear notes.
9. 2009 Toyota 2GR-FE V6, Lotus Evora
Finally, the Evora took Lotus into six-cylinder territory. Introduced in 2009, it used Toyota’s 3.5-liter 2GR-FE V6. In naturally aspirated form, SlashGear says it made about 276 horsepower.
Later, Lotus added a supercharger. For example, SlashGear puts the Evora S and Evora 400 at 345 to 400 horsepower. By comparison, Motoring Research says later Evoras reached 430hp, and SlashGear says today’s Emira V6 still runs a supercharged 3.5-liter Toyota engine.
