What is a sleeper car? It’s a car that looks slow or just ordinary, but has a powerful engine within that will surprise even the fastest sports cars at a stop light.
5. Mercedes-Benz G65 AMG
This off-roader is simply crazy. It’s basically a tough military 4×4 vehicle with three locking differentials (front, center, and rear) that has luxurious appointments, low profile tires, and an insane 621 horsepower twin-turbocharged V12 under the hood. The G65 looks square and slow, but best of luck to you if you are trying to overtake it on a highway on-ramp. It can blow your doors off.
4. Chevrolet SS
The SS sedan has an appearance of a regular family sedan. A layman may mistake the Chevy SS for a Malibu. However, there is a Corvette engine hiding under the hood, and that is always a great thing. The 6.2-liter V8 puts out 415 horsepower and 415 lb-ft of torque. It is a large rear-wheel-drive sedan that will go like stink.
3. Volvo XC60 T6 Super-Turbo
Is this just a regular midsize crossover. Sure, it is. The secret comes in the form of the 2.0-liter super-turbo engine. What does this all mean? The little four-cylinder motor produces 302 horsepower and 295 lb-ft of torque. There is supercharger that provides boost at lower rpms. It disengages at higher rpms and lets the turbocharger take over. This helps eliminate turbo lag off the line, provides usable real-world efficiency when the power is not needed.  The engine in the XC60 T6 Drive-E is paired to an 8-speed automatic and an AWD system.
2. Tesla Model X
Tesla describes the acceleration of the Model X very simply as “Ludicrous”. This basically a three-row crossover that can transport seven people. The slowest Model X is the 75D model. It is rated at 6.0 seconds 0-60 MPH. If you pay extra, you can step up to the P90D Model X with Ludicrous mode. It has the 90 kWh battery, 250 miles of electric range, and a 0-60 MPH rating of 3.2 seconds.
1. Ford F-150 2.7L EcoBoost
The small displacement twin turbo-charged F-150 2.7-liter V6 produces 325 horsepower and 375 lb-ft of torque. The internal codename for this engine within the Ford truck development team is “nano”. However, this nano engine produces impressive numbers and very impressive acceleration. In our testing, (you can see the results at TFLtruck.com) this is the second quickest 0-60 MPH truck we tested at a mile above sea level.
