The third-generation MR2 was marketed as the Toyota MR-S in Japan, Toyota MR2 Spyder in the US, and the Toyota MR2 Roadster in Europe.
The newest MR2 took a different approach than its predecessor, most obviously becoming a convertible and receiving the 'Spyder' marketing nomenclature.
Spyder interior
The first prototype of MR-S appeared in 1997 at the Tokyo Motor Show. The MR2 Spyder chief engineer Harunori Shiratori said, "First, we wanted true driver enjoyment, blending good movement, low inertia and light weight. Then, a long wheelbase to achieve high stability and fresh new styling; a mid-engine design to create excellent handling and steering without the weight of the engine up front; a body structure as simple as possible to allow for easy customizing, and low cost to the consumer."[22]
The only engine available for the ZZW30 was the all-aluminium 1ZZ-FED, a 1794 cc inline-four. Like its predecessors, the engine used dual overhead camshafts and 16 valves. The intake camshaft timing was adjustable via the VVT-i system, which was introduced earlier on the 1998 MR2 in some markets. Unlike its predecessors, however, the engine was placed onto the car the other way round, with the exhaust manifold towards the rear of the car instead of towards the front. The 138 hp (104 kW) maximum power was quite a drop from the previous generation, but thanks to the lightness of the car it could still move quite quickly, accelerating from 0 to 100 km/h (62 mph) in 6.8 to 8.7 s depending on the transmission option,[34][35] the Sequential Manual being unable to launch and shift as quickly as the clutch operated manual. Curb weight was 2,195 pounds (996 kg) for manual transmission models.
In addition to the 5-speed manual transmission, a 6-speed manual or 5-speed Sequential Manual Transmission (SMT) was also available starting in 2002. SMT is standard feature in Australian market; however, air conditioning was optional. After 2003, a 6-speed SMT was an option. The SMT had no conventional H-pattern shift lever or clutch pedal. The driver could shift gears by tapping the shift lever forward or backward or by pressing steering-wheel mounted buttons. Clutch engagement is automatic, and the car will automatically shift to second and then first gear when stopping. Cruise control was never offered with the manual transmission, but was standard for SMT cars.
The MR2 Spyder featured a heated glass rear window. A hard top was also available from Toyota in Japan and Europe.
The 1ZZ-FED is similar to the 1ZZ-FE but is built in Shimoyama, Japan. Output is 140 hp (104 kW) at 6400 rpm with 126 ft·lb (171 N·m) of torque at 4200 rpm. It uses MFI fuel injection, VVT-i and light weight, cast rods.

The 2ZZ-GE is a 1.8 L (1796 cc or 109.6 in³) version built in Japan. Bore is 82 mm (3.23") and the stroke is 85 mm (3.35"). It uses MFI fuel injection, has VVTL-i, and features forged steel connecting rods. Compression ratio is 11.5:1, necessitating "premium" gasoline (95 octane or above in the (R+M)/2 scale used in North America[5]). Power output for this engine varies depending on the vehicle and tuning, with the Celica GT-S, Corolla T-Sport,[6][7] Lotus Elise and Lotus Exige offering 141 kW (189 hp), but the American versions of the 2003 Matrix and Pontiac Vibe versions developing only 180 hp[5] with all later years offering anywhere from 173 hp in 2004 to 164 hp in 2006 due to a recurved powerband. The differing power figures from 2004 through 2006 are due to changes in dynamometer testing procedures. The Australian variant Corolla Sportivo has 141 kW@7600 and 181N·m torque. Due to noise regulations, Toyota recalled them for a flash of the PCM to up their output to classify them in the more lenient "sports car" noise category. The Corolla Compressor and Lotus Exige S add a supercharger with intercooler to achieve 225 hp (168 kW), while the Exige 240R's supercharger increases output to 240 hp (179 kW). The addition of a non-intercooled supercharger to the Elise SC produces 218 hp (163 kW) with a considerable weight saving. The supercharged engines are not labeled 2ZZ-GZE.
Unique to the ZZ family, the 2ZZ-GE utilizes a dual camshaft profile system (the "L" in VVTL-i, known by enthusiasts and engineers alike as "lift" similar to Hondas VTEC) to produce the added power without an increase in displacement or forced induction. The 2ZZ-GE was the first production engine to combine cam-phasing variable valve timing with dual-profile variable valve timing in the American market. The table below lists the specifications of the two camshaft profiles.
