BMW M5 v Audi RS6 GT v Porsche Turbo S v AMG GT: DRAG RACE

The video features a drag race between four German performance cars to determine which is the fastest over a standing quarter mile. The contenders are the Audi RS6 GT, the Mercedes-AMG GT63S, the BMW M5 Touring, and the Porsche Panamera Turbo S E-Hybrid. The Audi RS6 GT has a 4-liter twin-turbo V8 engine, producing 630 horsepower and 850 Newton-meters of torque, an 8-speed automatic gearbox, and all-wheel drive. It weighs 2.1 tons. The Mercedes-AMG GT63S also features a 4-liter twin-turbo V8, but with 640 horsepower and 900 Newton-meters of torque, a 9-speed automatic transmission, and all-wheel drive. It is slightly lighter at 2 tons. The new BMW M5 Touring is a 4.4-liter twin-turbo V8 hybrid, boasting 727 horsepower and 1,000 Newton-meters of torque. It has an 8-speed automatic gearbox, all-wheel drive, and is the heaviest car at 2.5 tons. Finally, the Porsche Panamera Turbo S E-Hybrid is powered by a 4-liter twin-turbo V8 hybrid system, delivering the most power at 782 horsepower and 1,000 Newton-meters of torque. It uses an 8-speed automatic gearbox and all-wheel drive, weighing 2.4 tons. The drivers introduce themselves and their cars. Yanni drives the Audi RS6 GT, Matt is in the BMW M5 Touring, Sam is in the Mercedes-AMG GT63S, and Rory drives the Porsche Panamera Turbo S E-Hybrid. There's some playful banter about car aesthetics, power, and potential for victory. Rory's Porsche is noted for having the most power and the highest price. The first drag race begins. The Porsche, driven by Rory, takes off incredibly fast, leaving the other cars behind. Yanni, in the Audi, experiences an issue where his car didn't change gear automatically as expected, leading to a poor launch and falling significantly behind. Matt and Sam suggest Rory might have jumped the start. Yanni also mentions that Sam, the Mercedes driver, advised him to use manual mode for the launch, which might have contributed to his car's gear-changing issue. After some discussion, it's decided to re-run the race, with Yanni ensuring his car is in sport mode, not manual, and with traction control fully off. Before the re-run, they conduct a rolling race to test how the cars perform when accelerating from a cruising speed, simulating a motorway overtake. The cars are set in their most relaxed "cruisy" settings. Matt, in the BMW hybrid, finds that his car was in electric mode at 50 mph, and when he floored it, the engine and gearbox took too long to "wake up," causing him to be left behind by the Audi and Mercedes. The Mercedes, despite being an older model, performs exceptionally well, surprising everyone. Rory, in the Porsche, also experiences a delay with his gearbox kicking down. This rolling race highlights a potential disadvantage for the hybrid cars in this specific scenario. They decide to do another rolling race, this time with the cars prepared for immediate acceleration, with engines on and in the correct gear. Rory expresses more confidence in this setup for his heavy but powerful Porsche. The Porsche performs much better in this race, demonstrating its speed when the engine is already engaged. Matt and Rory discuss the "benefit in kind" tax advantage of their hybrid company cars, which would be lower than the non-hybrid cars. Next, they perform a brake test to see which car can stop in the shortest distance. The Mercedes-AMG GT63S wins the brake test, followed by the Audi, then the BMW, and surprisingly, the Porsche comes in last, despite Porsches typically having excellent brakes. Finally, they proceed with the main drag race again, with all cars and drivers prepped, tires warmed, and Yanni's Audi in automatic mode to avoid previous gear issues. The first attempt sees the Porsche launch incredibly well again, leading to accusations of jumping, though Rory denies it. Yanni reports a good launch from his Audi. For the final decisive drag race, Matt aims for a better launch in his BMW. The Porsche once again demonstrates its superior speed, winning the race comfortably. The final results are: the Porsche Panamera Turbo S E-Hybrid in first place, completing the standing quarter mile in 10.7 seconds. The Audi RS6 GT takes second place, just ahead of the BMW M5 Touring, with both cars crossing the line in 11.3 seconds. The Mercedes-AMG GT63S finishes in last place with a time of 11.4 seconds.
