Is Infiniti's Variable Compression Turbo the Holy Grail of Power and Efficiency?

It was 1998 and my friend Tom had just picked up a 1991 Eagle Talon TSI AWD.

“Ok, go ahead and floor it, but don’t rev it past 5,000 rpm,” Tom said.

I mashed the throttle and … nothing happened.

We were moving, but it was at the pace of a Toyota Corolla and nowhere near the rate of acceleration promised by the 2.0-liter turbo’s claimed 195 horsepower.

Disappointed, I left my foot on the throttle for a few seconds. Suddenly, I heard the whistle of the spooling turbo and a sudden shove of boost kicked in.

Four-cylinder turbo engines from the ‘90s were all similar to this. While they generated relatively big power at the top end, they also suffered from massive turbo lag and had fuel economy similar to a much larger V8.

Nissan’s new Variable Compression Turbo engine promises big power, minimal turbo lag, and decent fuel economy using some new trickery.

Is this the holy grail of turbocharged motors?

  • Mebgardner I owned 4 different Z cars beginning with a 1970 model. I could already row'em before buying the first one. They were light, fast, well powered, RWD, good suspenders, and I loved working on them myself when needed. Affordable and great styling, too. On the flip side, parts were expensive and mostly only available in a dealers parts dept. I could live with those same attributes today, but those days are gone long gone. Safety Regulations and Import Regulations, while good things, will not allow for these car attributes at the price point I bought them at.I think I will go shop a GT-R.

This will cover all manufacturing including a battery plant. Honda feels they'll save 20% on production costs having it all localized and in house.As @ Analoggrotto pointed out, another brilliant TTAC press release.

  • Tane94 A CVT is not the kiss of death but Nissan erred in putting CVTs in vehicles that should have had conventional automatics. Glad to see the Murano is FINALLY being redesigned. Nostalgia is great but please drop the Z car -- its ultra-low sales volume does not merit continued production. Redirect the $$$ into small and midsize CUVs/SUVs.
