About the Ferrari F189

The Tamiya Ferrari F189 is a replica of the Ferrari F1-98, or as it was named officially, the Ferrari 640.
The Ferrari 640 was the Formula One racing car with which the Ferrari team competed in the 1989 season. It was driven by Nigel Mansell and Gerhard Berger.
The 640 was powered by Ferrari's own 3.5 litre V12 engine which produced up to 660bhp. The transmission it was mated to was the very first 7-speed semi-automatic gearbox seen in F1.
A revised version of the 640 appeared at the Mexican Grand Prix with a conventional airbox above and behind the driver's helmet
Tamiya made a model of the late version, as seen in the first four pictures here. The Late version was introduced to the fourth race in the Mexican GP.
Second last picture is the early version of the 640, note the different air scoop above the driver's helmet
Last picture is Gerhard Berger's early version, also seen in the picture above, in the rear.
