* Top Speed: If you're looking for the highest top speed, the Porsche Panamera Turbo S E-Hybrid currently holds the crown with a top speed of 196 mph (315 km/h).
* 0-60 mph Time: For acceleration, the Porsche 918 Spyder holds the record at 2.5 seconds. However, this is technically a plug-in hybrid, and it's no longer in production.
* Track Performance: For overall performance on a racetrack, the Porsche 911 Turbo S is a strong contender, and even though it's not strictly a hybrid, it uses a 48-volt mild hybrid system to improve efficiency and performance.
Ultimately, the "fastest" hybrid car depends on your definition of "fast." If you're looking for the fastest in terms of top speed, acceleration, or track performance, there are a few different models to consider.
