Don't Go All Hybrid/Turbo/Electric/Fuel Cell Just Yet - Toyota V6 And V8 to Gain "Dynamic Force" Camry Engine Tech

Forget hybrids. Set aside, for this moment, plug-in hybrids as well. Ignore the EV hubbub and the pie-in-the-sky hydrogen fuel cells. While you’re at it, remove turbochargers and their accompanying displacement reductions from your memory, too.

The naturally aspirated internal combustion engine has legs. The proof is in the 2018 Toyota Camry’s 2.5-liter Dynamic Force four-cylinder. With no hybrid assist, no turbos, no cord that plugs into your garage wall, and no futuristic fuel source, the new Camry 2.5-liter produces 206 horsepower and hits 41 miles per gallon on the highway on regular 87 octane.

That’s 16-percent more power 24-percent more highway mpg than the 2017 Camry’s 2.5-liter four-cylinder. With improvements in conventional, naturally aspirated, gas-fired engines occurring in such leaps and bounds, it’s no wonder Toyota has bigger plans for the Dynamic Force blueprint.

According to Ben Schlimme, Toyota’s executive program manager for powertrains, says “Dynamic Force is not solely aimed at the 2.5-liter engine.” According to Automotive News, Schlimme says the tech featured in the Camry’s 2.5 is destined for other segments, and V6 and V8 editions are now in concept form.

Getting the 2.5 to make substantially more power, without turbocharging and without harming efficiency, involved focusing on good ol’ fashioned fundamentals: friction, air flow, and cooling. Fundamental ideals for engineers, they may be, but enhancing the powerplant required new approaches: “high-speed combustion technology and a variable control system,” Toyota says, with a widened angle between intake and exhaust valves, a laser-cladded valve seat, and “strengthened tumble flow and high performance injector” which improve the fuel/air mixture, among other changes.

Much of the work Toyota did to the 2.5-liter is based on the need to improve the efficiency of its hybrids. “Our electrification pathway relies on these improvements of our internal-combustion engine,” Schlimme says, “hence we put a lot of effort ensuring that this base engine delivers on those principles.”

It doesn’t sound like Toyota is preparing us for a 2025 in which there will be few dealers, a near-100-percent electric fleet, and extensive ride-sharing in autonomous Ubers. You’ll recall Mazda’s belief: internal combustion engines are in the works until at least 2050.

Whether Toyota takes conventional engines that far won’t soon be determined. But if the next iteration of the 2.5-liter Toyota four-cylinder makes similar advances, and if Toyota applies similar improvements to V6 and V8 engines, we won’t be disappointed by missing battery packs and absent turbochargers.

    While I wouldn't want to deprive the TTAC keyboard warriors the delight they attain in demeaning each other, I wonder if anyone has done an actual study comparing similar turbocharged and non-turbocharged engines? I'm old enough to remember when engines needed to be rebuilt at the 80-100,000 mile mark, and automakers struggled to achieve 20mpg in economy cars, with engines that produced double digit horsepower. However you look at it, this is a stunning achievement for Toyota.

    "a laser-cladded valve seat"?? Just what the flip is that? Sounds like something taken from the promotional material.

  • Redapple2 As stated above, gm now is not the GM of old. They say it themselves without realizing it. New logo: GM > gm. As much as I dislike my benefactor (gm spent ~ $200,000 on my BS and MS) I try to be fair, a smart business makes timely decisions based on the reality of the current (and future estimates) situation. The move is a good one.
  • Dave M. After an 19-month wait, I finally got my Lariat hybrid in January. It's everything I expected and more for my $35k. The interior is more than adequate for my needs, and I greatly enjoy all the safety features present, which I didn't have on my "old" car (2013 Outback). It's solidly built, and I'm averaging 45-50 mpgs on my 30 mile daily commute (35-75 mph); I took my first road trip last weekend and averaged 35 mpgs at 75-80 mph. Wishes? Memory seats, ventilated seats, and Homelink. Overall I'm very pleased and impressed. It's my first American branded car in my 45 years of buying new cars. Usually I'm a J-VIN kind of guy....
  • Shipwright off topic.I wonder if the truck in the picture has a skid plate to protect the battery because, judging by the scuff mark in the rock immediately behind the truck, it may dented.
  • EBFlex This doesn’t bode well for the real Mustang. When you start slapping meaningless sticker packages it usually means it’s not going to be around long.
  • Rochester I recently test drove the Maverick and can confirm your pros & cons list. Spot on.
