History:

The Toyota MR2 is a two-seat, mid-engined, rear-wheel-drive sports car manufactured in Japan and marketed globally by Toyota from 1984 to 2007 over three generations: W10 (1984–1989), W20 (1990–1999) and W30 (2000–2007). It is Japan’s first mid-engined production car.

Conceived as a small, economical and sporty car, the MR2 employed straightforward design elements, including fully independent MacPherson strut front and rear suspensions, four-wheel disc brakes, and a transverse-mounted inline-four engine.

The name MR2 stands for either «mid-ship run-about 2-seater» or «mid-engine, rear-wheel-drive, 2-seater». In French-speaking markets, the MR2 was renamed Toyota MR due to the similarity of the word «MR2» to a French profanity.

First generation (W10; 1984–1989)

Toyota introduced the first-generation MR2 in 1984, designating it with the «W10» model code. When equipped with the 1.5-liter 3A engine, it was known as «AW10». Also, the 1.6-liter 4A version is identified with the code «AW11».

In Japan, the MR2 was marketed exclusively through the Toyota Auto Store and Toyota Vista Store, both rebranded in 1998 as the Netz Toyota Store. At its introduction in 1984, the MR2 won the Car of the Year award in Japan.

As Toyota designed the MR2 to accommodate a 2-liter engine, [7] its main features included its lightweight body (as low as 950 kg (2,094 lb) in Japan and 1,066 kg (2,350 lb) in the US), Strong handling, and low power small displacement engine. The car is often referred to as AW11, referring to the chassis code of more common 1.6-liter A-engine versions.

The MR2’s suspension and handling were designed by Toyota with the help of Lotus engineer Roger Becker. [8] Toyota’s cooperation with Lotus during the prototype phase can be seen in the AW11, and it owes much to Lotus sports cars of the 1960s and 1970s. Toyota’s active suspension technology, called TEMS, did not install. With five structural bulkheads, the MR2 was quite heavy for a two-seater of its size.

Toyota used the 1,587 cc (1.6 L; 96.8 cu in) naturally aspirated 4A-GE inline four-cylinder engine, a DOHC four-valve-per-cylinder engine, borrowed from the E80-series Corolla. This engine was also equipped with Denso electronic port fuel injection and T-VIS variable intake geometry, giving the engine a maximum power of 112 hp (84 kW) in the US, 128 hp (95 kW). ) in the UK, 116 or 124 PS (85 or 91 kW; 114 or 122 hp) in Europe (with or without catalytic converter), [11] 118 hp (88 kW) in Australia and 130 PS (96 kW; 128 hp) in Japan. The Japanese models were then detuned to 120 PS (88 kW; 118 hp). A five-speed manual transmission was standard, with a four-speed automatic available as an option.

Road tests returned 0-60 mph (97 km / h) times in the mid to high range of 8 seconds and 1⁄4 mile (402 m) times in the mid to high range of 16 seconds, significantly more faster than the four-cylinder Pontiac Fiero or Fiat X1 / 9. In the domestic market, the base model AW10 was offered, which used the more economical 1,452 cc (1.5 L, 88.6 cu in) 3A-U engine. with a nominal power of 61 kW (82 CV).

In 1986 (1988 for the US market), Toyota introduced a supercharged engine for the MR2. Based on the same block and header, the 4A-GZE was equipped with a small Roots-type supercharger and a Denso intercooler. T-VIS was removed and the compression ratio was lowered to 8: 1. It produced 145 hp (147 PS; 108 kW) at 6,400 rpm and 186 N⋅m; 137 lb⋅ft (19 kg⋅m) of torque at 4,400 rpm and accelerated the car from 0 to 100 km / h (62 mph) in 6.5 to 7.0 seconds. The supercharger was belt-driven but driven by an electromagnetic clutch, so it was not engaged except when necessary, increasing fuel economy. Curb weight increased to 2,494 lb (1,131 kg) for the supercharged models, due to the weight of the supercharger equipment and a new stronger transmission. A fuel selector switch was also added in some markets, to allow the car to run on regular unleaded fuel if needed. In addition to the new engine, the MR2 SC was also equipped with stiffer springs and received special «tear» aluminum rims. The engine cover had two raised vents (only one of which was functional) that visually distinguished it from naturally aspirated models. It also had the «SUPER CHARGER» label on the rear trunk and on the body moldings behind both doors. This model was never offered outside of the Japanese and North American markets, although some cars were imported privately to other countries.
