Infiniti’s Variable Compression Engine Produces 268 HP, Debuts In The 2019 QX50

Infiniti is gearing up to introduce the 2019 QX50 at the Los Angeles Auto Show and the company recently invited a handful of journalists to try out the model’s new turbocharged 2.0-liter four-cylinder engine with variable compression technology.

Automotive News was one of the companies that attended the event and they are reporting the new engine produces 268 hp (200 kW) and 288 lb-ft (390 Nm) of torque. This will reportedly enable the QX50 to accelerate from 0-60 mph faster than any of its four-cylinder competitors.

While the performance is impressive, the technology and design of the engine is what really sets it apart. As the publication explains, the engine is equipped with an electrically controlled actuator and a unique “elliptic device” called a multilink. These two components, along with some clever engineering, allow the engine to adjust its compression ratio from 8:1 to 14:1.

Thanks to variable compression technology, the engine manages to be both powerful and fuel-efficient. Infiniti hasn’t released detailed fuel economy figures but Nissan’s chief powertrain engineer, Shinichi Kiga, said the new QX50 will have a combined fuel economy rating that is 27 percent higher than the outing model which has a 3.7-liter V6 engine that develops 325 hp (242 kW) and 267 lb-ft (361 Nm) of torque.

The engine will be connected exclusively to a continuously variable transmission and it should allow the model to return around 26 mpg combined. Automotive News says the engine offered outstanding performance and refinement during test drives but noted the engine requires premium fuel.

    From a great sounding v6 to a Turbo 4 with a CVT. Will they loose customers? Yes.

    Infiniti is on the rise, the design of the qx50 becomes very nice

      3 comments to make 1 point? No, Infiniti is certainly not on any “rise”. While this is a move in the right direction, it takes far more than 1 innovative engine to make a great auto company. And their drive-by-wire was globally derided and remains rather poor compared to the industry’s best even today. This engine alone is impressive, yes, and more of use for an upgrade option for Nissan than fitting for a luxury automobile brand where beautiful engine noise, fast shifting DCT’s, and BIG power remain de rigueur relegating farty 4-cylinders to base-model duty. At best, this is on the surface a promising new engine from a struggling, second-rate luxury brand and perhaps an appreciable step in the right direction.

    this is true lead by technology, Q50 is first car ever with drive-by-wire and the new Infiniti QX50 ist the first car ever with variable compression engine

  • Autoexperte

    impressive engineering

  • ediotsavant

    Not impressed.

  • Rocket

    I’m excited to try the engine, but I’m disappointed in the move to FWD, and I’m absolutely horrified by the move to a CVT. Fuel economy matters … I get it. But I also get that premium brands need to provide a premium experience. I’m quite confident nobody has ever described a CVT experience as “premium”.

    Make it a straight 6

  • Six Thousand Times

    Pity we’re not being introduced to it in the new Silvia.

  • Tumbi Mtika

    This should have been an inline-six. This should have been RWD.

  • SteersUright

    CVT have no business being employed in luxury cars where performance and emotion trump efficiency. Fine for Nissan, a misstep for Infiniti. They are truly lost, residing on an island somewhere along with Acura and Cadillac.

  • Vassilis

    Very interesting engine concept.

  • botornot387

    Make a great engine and then connect it to a shit gearbox. DOA

  • I can never understand why people hate CVTs so much, paired with a proper engine I love them.

    The 2 years I drove the Murano the engine was one of the best attributes for that car and I can’t wait to reunite with the gearbox in the Lexus LS someday.
