Visually, the Pur-R-Rim aero package consists of a front spoiler and fascia with integrated LED daytime running lights, ventilated replacement fenders and side skirts. Cars fitted with the AMG kit get a sportier lower lip, while the CLS 63 AMG goes one step further with a larger item constructed from clear-coated carbon fibre.
Brabus offers its usual range of alloy wheels, including the Monoblock F, Q or R designs, in sizes ranging from 8.5 x 17 to 10.5 x 20-inches, while the lowering of this luxury hearse can be carried out with either a simple set of sports springs, a full replacement system or the company’s electronic module for cars equipped with Airmatic air suspension, providing a drop of around 35 mm in tide height.
Performance upgrades are available for each engine, with the 250 CDI getting a 23 kW (31 hp) jump from 150 kW (204 hp) and a new torque figure of 560 Nm. The 350 CDI enjoys a rise from 195 kW (265 hp) and 620 Nm to to 230 kW (313 hp) and 690 Nm, allowing a 0-100 km/h time of 5.9 seconds and a limited top speed of 250 km/h (155 mph). After the 4.6-litre biturbo V8 in the CLS 500 has been tweaked, output climbs from 304 kW (408 hp) and 600 Nm to 368 kW (500 hp) and 720 Nm, which results in a new top speed of 300 km/h (186 mph).
Top of the food chain is the 5.5-litre biturbo-engined CLS 63 AMG model, which is fitted with additional software, a supplementary water-to-air intercooler and stainless steel exhaust system with adjustable butterfly valve, culminating in 455 kW (619 hp) and 1000 Nm, meaning 100 km/h happens in a mere 4.2 seconds and top speed is a bragworthy 320 km/h (200 mph). There’s also a limited-slip differential with a locking rate of 40 percent.
