By ditching the existing model’s 6.0-liter V12 for a de-tuned version of the Maybach engine, S600 power increases by 126 horsepower to 493 hp, with torque up by 199 lb-ft to 590 lb-ft. That’s enough, according to Mercedes-Benz, to lower the S600 0-62 mph time from 6.3 seconds to just 4.8 seconds. Top speed remains governed to 155mph, though the S600 is geared to top 180 mph without electronic intervention, according to Mercedes sources. If rumors are correct, look for the Maybach-based powerplant in the SL as well.
Haha, that's crazy, this huge thing going from 0-60 in 4.8, I wonder what the times for the SL600 is going to be.
