The capital E on the top gate of the shift pattern in early-1980s Volkswagen Rabbits and Golfs stood for Efficiency. Plenty of owners read it as Economy, or as a bonus extra gear, and the guesses stuck for decades. The letter marked an overdrive ratio that let the engine loaf on the highway and sip less fuel.

That small letter pointed at a larger story about the oil-shock years, when fuel prices and tightening efficiency rules pushed automakers toward cheap mechanical fixes. Volkswagen did not wait for fuel injection or extra cogs to arrive. It lengthened the top gear, sold the idea as a package in Europe, and left a letter on the shift pattern that owners kept misreading.
Overdrive gearing: 0.70:1 and 2,500 rpm at 60 mph
Carscoops writer Thanos Pappas reported on November 1, 2026 that Volkswagen documents confirm the word is Efficiency, not Economy and not Extra. The 3+E and 4+E manual gearboxes went into the original Golf, the Jetta and the U.S.-spec Rabbit. In the E position the box ran a 0.70:1 overdrive through a 3.89:1 final drive, which dropped engine speed to about 2,500 rpm at 60 mph.
A parts-catalog table on a Mk1 Golf transmission page gives the same shape of numbers, with small rounding differences. Its 3+E codes from 1981 list ratios of 3.45, 1.75 and 1.06 for the first three gears and 0.71 for E, set against 3.45, 1.94, 1.28 and 0.91 in a conventional four-speed. The overdrive therefore sits well beyond what the ordinary fourth gear offered, and the three lower gears are spaced closer together than in the standard box.
The 1981 Rabbit LS used the 3+E arrangement, which Carscoops describes as effectively a four-speed casing with wider spacing. First, second and third covered roughly 90 percent of urban and back-road driving, while E suited steady highway cruising and called for a downshift to reach full power. The reward, according to the same report, was a climb from 24 to 28 mpg and highway figures reaching 42 mpg.
The 1981 Formula E package in Europe
Volkswagen’s own newsroom history of the first Golf, which started production on March 29, 1974 and reached about 6.9 million units, mentions the efficiency gearing directly. A longer fifth gear arrived in the optional 4+E transmission in 1980. The company’s first-generation Golf history adds that a 1981 Formula E version for the 1.1-liter and diesel models combined a 3+E gearbox with a better drag coefficient, a gear-shift indicator and a fuel-consumption display.
Press testing at the time put numbers on the idea. A retrospective from Zwischengas cites Auto Motor und Sport, issue 6/1981, for consumption of 6.68 liters per 100 km in the Polo, a 17.5 percent saving, 7.50 in the Golf at 15 percent and 8.65 in the Passat at 9.7 percent. The package was an extra-cost option and could include a GTI-style spoiler on the Golf, a tuned high-compression 1.1-liter engine in the Polo and Derby, and a start-stop system on the Passat. In a long-distance test toward France, the Passat covered almost 1,000 km on one tank.
Carscoops adds that an electro-vacuum computer compared engine load with rpm and lit an amber arrow in the instrument cluster when the driver should upshift. The Formula E label ran across the European line-up from 1981 to 1985, including the Polo, Golf, Jetta, Scirocco, Passat, Santana, and the Audi 80 and 100. It has nothing to do with the electric racing series that borrowed the name decades later.
Bolt-on overdrives, the Rabbit name and the end after 1985
Earlier overdrives were separate hardware. British and European cars often carried external electro-hydraulic units, such as the Laycock de Normanville system, that bolted behind the gearbox and engaged from a dash switch or column stalk. Volkswagen built the overdrive inside the front-drive transaxle and put the control on the shift lever itself.
The nameplate adds a wrinkle. According to the Mk1 Golf entry, the car reached the United States and Canada in December 1974 as the Rabbit and was replaced there by the second-generation Golf in 1984. The 1.1-liter Formel E, rated at 50 PS and 8.0 liters per 100 km, appears in the European specification table for 1981 to 1983 rather than among North American models. Rabbit owners got the E gate, while the full efficiency trim belonged to Europe.
The idea faded after 1985, when electronic multi-point fuel injection, variable valve timing and standardized five- and six-speed manuals made the special gearboxes unnecessary, as Carscoops notes. Zwischengas also says some drivers disliked the very long top gears and that Audi and BMW offered similar setups. The variants were discontinued and are now rare. The original Volkswagen documents behind the Efficiency finding were not published in the sources reviewed, so the 0.70:1 and 0.71 figures remain the reported record rather than a scan of a factory sheet.
