Whether it’s turbocharged power or fuel-sipping economy, Altima's available VC-Turbo™ engine responds to your input instantaneously. [] It literally changes shape as it adjusts the compression ratio to maximize output or fuel economy. []
When you press on the gas, the piston moves to produce a lower compression ratio. Similar to when a sprinter crouches to launch off of the starting line, it results in instant V6-like power from this mighty 4-cylinder turbo engine.
When you cruise at lower speeds, the rotating assembly transforms to produce a higher compression ratio. And like the more relaxed stance of a long-distance runner, it conserves energy and increases your fuel economy. []
