To put this in perspective the Bugatti Veyron set a top speed record with a 254.05 mile per hour or 408.84 kilometer per hour run. The SuperSport that followed hit 267.856 mph or 431.072 kph. Yes, bested by a Mercedes from 1938 with a .18 coefficient of drag.
Here are the specs:
- Engine: MD 25 DAB/3 60 Degree V12
- Engine position: Front longitudinal
- Aspiration: Twin Roots superchargers
- Valvetrain: DOHC 4 valves per cylinder
- Displacement: 5,576.75 cc / 340.31 in³ (82.0 x 88.0 mm)
- Compression: 9.17:1
- Power: 541 kW (736 PS; 725 hp) @ 5800 rpm
- Power/displacement 131.97 PS (97.06 kW; 130.16 hp) per litre
- Power/weight: 621.1 PS (456.8 kW; 612.6 hp) per tonne
- Transmission: 4-speed manual
- Engine cooling: Ice supplemented normal coolant as air intakes were kept very small to improve aerodynamic flow over and around the car
Keep in mind the Veyron Super Sport made its top speed run on a test track and not on a public road. That makes what Mercedes pulled off 79 years ago all that much more impressive.
Will anyone top this record? Will any government let such a record try take place on a public road? Who knows. What is clear is that the W125 Rekordwagen was way ahead of its time.
