The added 295 lb-ft of torque from the electric motor is a hefty shove when the gas pedal is flat-an electric boost derived from the quickest car we've ever tested-the Porsche 918 Spyder.

You can drive it up to 83 mph in battery-only mode, and once the gas-engine kicks, up to 183 mph. Not only is the Porsche Cayenne Turbo S E-Hybrid the quickest and fastest Cayenne ever, it's the second quickest SUV we've ever tested. What do you get when you take Porsche's 541-hp twin-turbo V-8 and slap a 134-hp electric motor between it and an eight-speed automatic transmission? A whopping combined 670 horsepower with 633 lb-ft of torque for starters. Powertrain: permanent-magnet synchronous AC front motor, AC induction rear motor, 259- and 503-hp, 244 and 469 lb-ft combined output, 532 hp, 713 lb-ft 90.0-kWh lithium-ion battery pack, single-speed direct-drive transmission (front/rear).While this list surely will get more crowded in the near future as other fiery electric SUVs come to market, the people mover from the House of Elon is currently the quickest of the quick. Shout out to the all-wheel drive and 713 lb-ft of instantaneous electric torque for that breathtaking launch capability.

In our testing, a 2016 Ludicrous Speed–equipped P90D model (that’s the Performance trim of the X with the 90.0-kWh battery pack, which has since been discontinued in favor of the even-quicker 100D models) warped to 60 mph in 3.2 seconds and covered the quarter-mile in 11.6 at 116 mph. Peak acceleration in the Model X is a kick to the backside. After all, it has an available Ludicrous driving mode. Its falcon-wing rear doors may be silly and its lack of small explosions under the hood might disappoint internal-combustion fans, but there’s no denying that Tesla’s crossover is ludicrously quick.
