Accord Performance: Turbocharged and Electrified – The 2018 Accord takes an entirely new approach to performance by featuring three advanced new powerplants – two direct-injected and turbocharged 4-cylinder engines and the third generation of Honda’s two-motor hybrid powertrain technology. The 2018 Accord also features a new Honda-developed 10-speed automatic transmission (10AT) with the 2.0-liter turbo engine, the first of its kind for a front-wheel-drive car, and an available 6-speed manual transmission for both turbocharged engines.
The new 1.5-liter, 16-valve DOHC direct-injected turbo with dual Variable Timing Control (dual VTC) produces a peak 192 horsepower (HP) at 5,500 rpm and 192 lb-ft. of torque from 1,500 to 5,000 rpm, up from 185 HP at 6,400 rpm and 181 lb.-ft. at 3,900 rpm on the existing, normally aspirated 2.4-liter model. The new 1.5-liter turbo is mated to a Honda continuously variable automatic transmission (CVT) or, in Sport trim, to a CVT or a 6-speed manual transmission (6MT).
The Accord can also be equipped with a new 2.0-liter 16-valve DOHC direct-injected turbo with i-VTEC valvetrain paired with a 10-speed automatic transmission or, in Sport trim, to the 10AT or an available 6MT. The new 2.0-liter turbo, sharing much of its design with the race-bred 2017 Civic Type R, produces 252 HP at 6,500 rpm and 273 lb.-ft. of torque from 1,500 to 4,000 rpm, compared to 278 HP at 6,200 rpm and 252 lb.-ft. at 4,900 rpm for the 3.5-liter V6 that it replaces.
Both turbocharged engines utilize a host of new technologies, including high-efficiency low-inertia turbos, variable valve timing, low-pressure-loss air intake and high-accuracy direct injection, to deliver immediate and powerful response along while still anticipated to receive top level fuel economy ratings. The two new automatic transmissions – the CVT for the 1.5-liter engine and new 10AT for the 2.0-liter engine – take greater advantage of available torque while maximizing quietness and efficiency during highway cruising. The redesigned CVT has an 11 percent lower ratio compared to the current version for more powerful launch performance, while the new 10AT is 22 lbs. lighter, has a 68 percent wider overall ratio range with a 43 percent lower first gear, and a 17 percent taller top gear compared to the current Accord’s six-speed automatic.
Production of New Accord Hybrid Returns to Ohio
An all-new, even more refined and fuel efficient Accord Hybrid will be again built in Marysville, Ohio after a couple of years of production in Japan, and will be powered by the third-generation of Honda’s innovative two-motor hybrid technology, offering improved power delivery with no compromise to interior or cargo space and packaging.
The new hybrid powertrain will utilize a 2.0-liter Atkinson cycle engine with greater than 40 percent thermal efficiency, the highest for any mass-produced Honda engine, paired with Honda-developed electric motors that are the first drive motors in the world to use magnets containing no heavy rare-earth metals. As before, the Accord two-motor system operates without the need for a conventional automatic transmission.
Additionally, a new, more compact intelligent power unit (IPU), containing the hybrid battery pack and its control systems, is now mounted under the rear floor instead of in the trunk, preserving both cargo space (16.7 cu.-ft.) and the flexibility of a 60/40-split and folding rear seat, standard on all models and trims. Detailed specifications on the 2018 Accord Hybrid, including power and fuel-economy ratings, will be release closer to launch.
New Approach to Body and Chassis Design
The 2018 Accord’s new body structure is lighter and more rigid, utilizing 29 percent ultra-high-strength steel, the most extensive application of this weight-saving material in any current mass-produced Honda car. Overall, the new Accord employs 54.2 percent high strength steel (above 440 MPa).
Key body features include the latest generation of Honda’s Advanced Compatibility Engineering (ACE) body structure with crash stroke front frame, tailor-tempered rear frame members for improved crash-energy absorption, and the extensive use of structural adhesives for increased rigidity, cabin quietness and weight reduction. Total vehicle weight is down between approximately 110 to 176 pounds, depending on trim, while body torsional and bending rigidity are improved 32 and 24 percent, respectively, aiding ride quality, cabin quietness, and dynamic performance.
