I think some folks have some of the stats mixed and matched to make things seem more exciting, and those mixed and matched stats are getting passed around.

This is talking about the 1st gen.

As Toyota engineered the MR2 to accommodate a 2-liter engine,[6] its primary features included its light body (as low as 2,095 lb (950 kg) in Japan and 2,350 lb (1066 kg) in the US), strong handling and lightly powered, small-displacement engine. The car is often referred to as the AW11, referring to the chassis code of the most common 1.6-litre, A-engined versions.

Curb weight
1,035 kg (2,282 lb) (1985 NA)
1,066 kg (2,350 lb) (1988 NA)
1,131 kg (2,493 lb) (1988 SC)[5]

And this is about the 2nd gen.

The MR2 went through a redesign in 1989 (though North America did not receive them until late 1990 as 1991 models). The new car was larger, weighed 350 to 400 pounds (160 to 180 kg) more than its predecessor due to having a more luxurious and spacious cabin, larger engine sizes, sturdier transaxle, and a more durable suspension setup. The overall design of the automobile received a more rounded, streamlined styling, with some calling the MR2 SW20 a "baby Ferrari" as well as "poor man's Ferrari", since the car did have several design cues borrowed from Ferrari. The 348 was its direct contemporary.

1,250 kg (2,755 lb) (1993T GTS Hardtop)
1,310 kg (2,888 lb) (1991T T-top)
1,179 kg (2,599 lb) (1991NA)[22]

and 3rd gen

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,[52][53] the Sequential Manual being unable to launch and shift as quickly as the clutch operated manual. Curb weight was 2,195 lb (996 kg) for manual transmission models.
