What's all this about?

Long-time purveyors of Mercedes-based road weapons, Brabus has revealed two of its craziest creations yet; a 700hp S 63 4Matic and a 900hp Maybach S 650. Do not adjust your screen.

But, neither of those cars were slow to begin with?

That's the beauty of Brabus; take something that's already quite quick and make it obscenely so. The 'Brabus B40-700 PowerXtra' package for the S 63 amounts to little more than an ECU fettle, but the results are staggering. Power is now 700hp, torque output is 950Nm, 0-62 mph takes 3.3 seconds and a top speed of 186mph is achievable, with more speed allegedly on the way once Brabus gets its 'Vmax module' finished. Sounds NASA-y. We like.

And the Maybach?

Things got a little more serious for this one, as Brabus ripped out the existing motor, replacing it with their own, highly-tuned 6.3-litre twin-turbo V12. It's based on the 6.0-litre engine, but with intake, turbo, exhaust and electronic mods, as well as stronger internals, now makes 900hp and a stupendous 1,500Nm of torque. Top speed is 217mph, with 0-62mph achieved in 3.7 seconds.

The cars look a bit...tunerised.

Of course they do; that's the Brabus way. There's no point in having all that power if people don't know about it, is there? To be fair, all body modifications serve an aerodynamic purpose, and the 'Monoblock' wheels are quite nice in their own right, The S 63 gets a racier feel inside, with carbon fibre ousting the wood trim and lots of aluminium and Brabus badges around the place, while the Maybach S 650 keeps it classy, sticking to the luxury theme, and even includes two Microsoft tablet PCs and a specially-designed rear centre console for high-speed productivity. Push that envelope.
