Why Toyota Didn’t Add a Turbo Four in addition to Still Offers a V-6 inside 2018 Camry
Although the styling of the 2018 Toyota Camry revealed earlier which month at the Detroit auto show takes a daring turn just for which long-bland nameplate, at first glance the powertrain lineup looks to have been left behind inside radical remake. As before, there’s a base 2.5-liter inline four-cylinder, a V-6 for upper trim levels, in addition to a hybrid.
However, the basic descriptors are about where the similarities end. The displacements are the same, yet almost nothing carries over. The 2.5-liter used throughout much of the lineup (in addition to in hybrid products) can be an entirely brand new engine, while the hybrid system has been reworked, in addition to a brand new eight-speed automatic transmission has been introduced for all non-hybrid products.
With the flexibility of a clean-slate engine redo, we wondered: Why hasn’t Toyota moved to the brand new industry norm of turbocharged smaller-displacement, generally 2.0-liter, engines as embraced by the Chevrolet Malibu, the Kia Optima, in addition to the Hyundai Sonata? Why can be a V-6 still inside Camry lineup?
“The American customer loves a V-6, right? which can be my understanding of why we have to keep the V-6,” said Masato Katsumata, chief engineer for the 2018 Camry, in a roundtable at the Detroit show.
Bill Fay, Toyota Division group vice president in addition to general manager, said which he expects V-6 products to make up less than 10 percent of Camrys sold, yet Toyota sees continued demand coming from “a certain kind of customer who’s looking for which level of performance.” Toyota executives have inside past also called the V-6 Camry a dealer favorite, as which brings a higher-income customer into showrooms in addition to commands a higher sticker cost. Besides, Honda still offers a V-6 inside Accord, in addition to if there’s one competitor Toyota wants to match its lineup against, which’s the Accord.
Toyota makes a strong argument which its brand new four-cylinder engine, with its high-efficiency intake port in addition to high-airflow design, doesn’t need forced induction, in addition to the automaker hints which its performance will be edging closer to which of the V-6. Deputy chief engineer Keita Moritsu pointed out, as we followed up with more questions after the show, which the engine produces low-rev torque which’s comparable to supercharged engines, in addition to combined with its high-rev output, he said, which gives which an advantage among naturally aspirated engines.
40 Percent Thermal Efficiency, 20 Percent Better Fuel Economy
The brand new Dynamic Force four, which can be physically the same inside Camry in addition to Camry hybrid nevertheless tuned differently, promises some astounding efficiency improvements, too, which Toyota attributes to its long-stroke design, variable cooling system, multi-hole direct injection, in addition to high compression. The company claims 41 percent thermal efficiency inside Camry hybrid in addition to 40 percent inside standard Camry. which’s inside range which was the exclusive domain of diesel engines only a few years ago.
Toyota has not yet confirmed U.S. specifications for the Camry powertrains, which can differ significantly coming from specs on those sold in Japan. which said, Toyota claims about a 10 percent improvement in power in addition to approximately 20 percent better fuel economy for the Dynamic Force over today’s inline-four, which makes 178 horsepower in addition to 170 lb-ft of torque in addition to returns 24 mpg city/33 mpg highway (27 mpg combined). which suggests brand new power ratings above 195 horsepower in addition to an EPA combined rating of 32 mpg or better.
Today’s Camry hybrid can be rated at 42 mpg city/38 mpg highway (40 mpg combined), in addition to Toyota also points to a 20 percent improvement there—for 44 mpg combined, perhaps.
Although some Americans will avert their eyes coming from the sight of a hybrid badge, especially while gasoline prices remain low, chief engineer Katsumata can be convinced which which’s the hybrid product—not the V-6—which’s the best-driving Camry. which’s because the weight distribution can be more balanced in hybrid products, thanks to the battery pack located under the back seat.

“I believe you can enjoy the driving performance in a twisty road better than the V-6,” Katsumata said. “Of course in a long straight or up in addition to down, on a racetrack, the V-6 can be better.”
