The third generation MR2 had three different names, depending on country; Toyota MR-S in Japan, Toyota MR2 Spyder in the United States, and the Toyota MR2 Roadster in Europe. With the previous MR2 having been in the market for almost ten years, it was time for it to move aside as Toyota released the new MR2, designated ZZW30. The new MR2 was a part of Toyota Project Genesis, a plan from Toyota to attract buyers from the younger age bracket in an effort to increase sales in the United States, being one of Toyota’s worse flops, the project quickly ended in 2001, when Toyota launched its successful marque, Scion. The car received a complete makeover compared to the two previous models. One of the biggest changes was the replacement of the solid, T-Top, and sunroof options with a true convertible soft top, giving the car the ‘Spyder’ designation. Due to a new car design rule from SAE (The Society of Automotive Engineers), the pop-up headlights as seen on SW20 had to be removed. It is the only Toyota MR2 generation to not be sold in Canada.
The Second Generation MR2 (MKII) went through a complete redesign in 1989; the wheelbase had been increased by 3.2 inches, making it 94.5 inches, the overall length had been increased by 9.3 inches, making it 164.2 inches and is 66.9 inches wide. The new MR2 weighed 350 to 400 pounds more than its predecessor and had smoother bodylines. It appeared very advanced for its era. Now that the MR2 was larger, it could be classed as a GT car. The 1990 model year MSRP ranged from approximately $14,368 to $18,558. Since the resemblance between the Ferrari 348tb and the Ferrari F355 and the new MR2 was quite striking, the MKII is sometimes referred to as a “poor man’s” Ferrari. Indeed, many bodykits became available to make the MKII imitate the Ferrari F355 with, sometimes, almost indistinguishable results.
There are many visual differences between the MR2 N/A and MR2 Turbo models which are much more noticiable to the owner of an MR2 Turbo: some include the “turbo” emblem (USDM) on the rear trunk, a fiberglass engine bonnet with “raised” vents, fog lights (some JDM and EU N/A models came with fog lights), and an added interior center storage compartment located between the two seats. All MKII’s came with a staggered wheel setup, which was slightly wider in the rear. In the U.S. there are two different chassis codes, SW21 for the MR2 N/A model and SW22 for the MR2 Turbo model, as opposed to the usual SW20 reference.
The small and light MR2, chassis code AW11, was something no one had expected from Toyota, known for their economical and practical cars. The two-seat MR2 was definitely not practical as a family car, but the design criteria were different from that of most previous cars. Cars with a similar design and the same concept were the Lancia Beta Montecarlo, Fiat X 1/9 and the exotic Lancia Stratos, all produced in the 70s. The most important features of the AW11 were its light body (as low as 2,200 lb (998 kg) in Japan and 2,350 lb (1066 kg) in the US), superior handling and lightly powered, small-displacement engine. Toyota’s cooperation with Lotus during the prototype phase can be seen in the AW11, and it owes much to Lotus’s legendary sports cars of the 1960s and 1970s.
As a powerplant, Toyota chose to use the naturally aspirated 4A-GE 1587 cc I4 engine with Double overhead camshafts, which allowed the use of 16 valves for a better gas flow through the combustion chamber. The engine was also equipped with DENSO electronic multi-point fuel injection and a variable intake geometry (T-VIS), giving the engine a maximum power output of 128 hp (95 kW). US engines were rated at 112 hp (84 kW), European engines at 124 hp (93 kW), Australian engines at 118 hp (88 kW) and Japanese engines at 130hp (97 kW). The engine had already been introduced earlier on the Toyota AE86, gathering a lot of positive publicity. There was also a JDM model AW10 which used the more economical 1452 cc 3A-U engine, but it didn’t gain too much popularity. Some versions were also fitted with automatic climate control.
