SM, since the very first day of their establishment, have been known to produce perfect specimens of engineering perfection. With the 555 Turbo R, they have pushed the boundaries even further. The car's acceleration is matched by only a few other road-legal cars reaching 0-100 km/h in just 2.8 seconds and continues to accelerate all the way up to 340 km/h. Powering the car to produce such an impressive performance is a 4.0-litre, H6, twin-turbocharged engine that develops 620 horsepower and 840 Newton metres of torque. The 555 Turbo R certainly makes its presence felt on the road, if you fail to see it first, you will hear it coming. Seeing one on the road, though, will be a rare occasion as only three hundred of them were ever built.
