The luxo-barge’s 6.0-liter twin-turbo V12 has been upgraded to produce 900 PS (887 hp / 662 kW) and 1,500 Nm (1,106 lb-ft) of torque. We don’t know yet what Brabus did to it to come up with these staggering numbers, but it’s a huge increase compared to the stock S650’s 630 PS (621 hp / 463 kW) and 1,000 Nm (738 lb-ft) of torque.
Anyone who can afford to pay a six-digit sum for a car won’t be too concerned about fuel prices. However, the tuner did release the estimated fuel consumption for the new Brabus 900, which gulps 11.9 lt/100 km (23.7 mpg UK / 19.8 mpg US) on average.In the city, that number goes up to 17.1 lt/100 km (16.5 mpg UK / 13.8 mpg US), and on the highway, it drops to a very satisfying 8.6 l/100 km (32.8 mpg UK / 27.4 mpg US). Moreover, despite the massive output, CO2 emissions are a relatively reasonable 279 g/km.
Elsewhere, the tuned S650 has a new front bumper, different rims and Brabus logos. The cabin is as luxurious as you’d expect it to be. This example boasts brown leather on pretty much every visible surface, has a rear-seat entertainment system and ‘Brabus’ entrance lights, as well as other bits and pieces that will be detailed next week at the Geneva Motor Show, when the 900 will be officially unveiled.
