May 17, 2007 The BRABUS S V12 S Biturbo coupe is not just the most powerful coupe in the world - it is also the fastest street-legal coupe. It’s vital performance statistics of 0 – 100 km/h in 4.0 seconds, 200 km/h after just 11.9 seconds and an electronically limited top speed of 340 km/h are all without equal. Based on the latest Mercedes CL 600 model, the SV12 S Biturbo coupe can be ordered as a complete car starting at 178,980 Euros or can be built based on an existing current CL 600 model. The engine is based on the turbocharged Mercedes 600 twelve-cylinder engine and represents the most powerful street-legal V12 engine in the world producing 730 hp / 537 kW at 5,100 rpm. Just as extraordinary is the peak torque of 1,320 Nm at just 2,100 rpm, which is limited electronically to 1,100 Nm. The mods are extensive, starting with installing a special BRABUS crankshaft with longer stroke, combined with a bigger bore and correspondingly sized forged pistons, increases displacement from 5.5 to 6.3 liters. After that, the cylinder heads are precision-machined and four new camshafts are fitted, two new exhaust manifolds, two larger turbochargers, a high-efficiency intercooler and a high-performance exhaust system with metal catalysts and low back pressure.
