Nissan Altima has a 188-hp 2,5-liter 4-cylinder engine. It is possible to increase power to 248 horsepower and use CVT. One can do that with the help of additional turbocharged two-liter 4-cylinder. Altima has not given up on the sedan, as the test drives showed. Note that 2,5-liter engine comes with all-wheel drive. As the driver presses the gas pedal, the engine goes louder. The model is a bit too noise at times. If you add the VC-Turbo engine, the vehicles will go significantly faster.
