Providing ample power for the new BMW M5 is a 4.4-litre V8 bi-turbo engine with M TwinPower Turbo technology. The M engineers have carried out significant revisions to the outgoing model’s power unit. For example, newly developed turbochargers, ultra-efficient indirect charge air cooling and increased fuel injection pressure together help to raise output and, above all, torque. The engine develops 441 kW/600 hp at 5,600 – 6,700 rpm, while a monumental 750 Nm (553 lb-ft) of torque is placed at the driver’s disposal from as low down as 1,800 rpm and remains there until 5,600 rpm. A map-controlled, fully variable oil pump ensures oil is supplied as and when the new BMW M5 needs it, even on the track. The car’s impressive performance figures speak for themselves: 0 to 100 km/h (62 mph) in just 3.4 seconds, 0 to 200 km/h in 11.1 seconds (124 mph). Top speed, meanwhile, is an electronically limited 250 km/h (155 mph), but the optional M Driver’s Package can keep the fun coming to 305 km/h (189 mph).
The meat of the advanced 2018 Porsche Panamera Turbo S E-Hybrid powertrain is the same 4.0-liter twin-turbo V-8 from the Panamera Turbo, churning out 542 hp and 567 lb-ft of torque. Sandwiched between the engine and eight-speed PDK dual-clutch automatic is an electric motor that adds 134 and 295 lb-ft to the equation. Porsche rates the Panamera Turbo S E-Hybrid’s total system output at 671 hp and 626 lb-ft.
