Gas vs. Diesel vs. Hybrid: The Drag Race
The indefatigable British team CarWOW never fails to surprise us with fresh ideas for drag strip action. This time around, it came up with a four-car showdown where little spec comparison could be made between any two entries.
The first contender is an Audi S4 Avant, which packs a 3.0-liter, six-cylinder TDI engine churning out 347 horsepower (259 kilowatts) along with 700 Nm (516 lb-ft) of torque. The diesel mill is turbo- AND supercharged at the same time, and comes with a 48V electric starter add-on contributing 11hp (8 kW) of its own. The transmission is eight-speed automatic, and the curb weight amounts to 1,855 kilograms (4,090 pounds).
The second entry – a BMW M340i xDrive – features the same displacement and cylinder count, but chugs gasoline and has no hybrid attachments. It comes manufacturer-rated for 374 hp (279 kW) and 500 Nm (369 lb-ft) of torque and also uses an eight-speed auto gearbox. Not being a hybrid car enables it to weigh in at just 1,545 kilos (3,406 lbs).
In contrast, the Mercedes-AMG E 53 4Matic does not shun from electrified drivetrain tech. Its 3.0-liter turbo-six gas engine benefits from an electric supercharger and a starter-generator that gives it 22 hp (16 kW) along with 250 Nm (184 lb-ft) of torque. The resulting combined output amounts to a respectable 435 hp (324 kW) and 520 Nm (384 lb-ft). A nine-speed automatic is used, and the curb weight is predictably high at 1,970 kg (4,343 lbs).
The final contender is a Volvo S60 Polestar Engineered, which packs a humble 2.0-liter turbo V4 engine assisted by an electric motor rated at 87 hp (65 kW). The total output to the wheels amounts to 415 hp (309 kW) and 640 Nm (472 lb-ft) of torque. At 2,020 kg (4,453 lbs), it is also the heaviest of the four.

As it turned out, the drivetrain and weight differences had remarkably little effect on the outcome. All four cars ran the quarter-mile in the same amount of time, all four hit 80 km/h (50 mph) almost simultaneously, and all four finished the race with around 113 km/h (70 mph) on the counter. The sophisticated hybrid systems, despite adding between 300 and 400 kilograms (670 – 900 pounds) of weight to the cars they were installed upon, proved nearly useless in terms of sheer acceleration performance.
