The 10th-generation Accord is new from the ground up and features a lighter and more rigid body structure, an advanced new chassis design, two all-new, high-torque direct-injected and turbocharged engines, the world's first 10-speed automatic transmission for a front-drive car and a new generation of Honda's two-motor hybrid technology, along with a host of new safety, driver-assistive and connected-car technologies – all wrapped in a more sophisticated, sleek and athletic design with top class interior space and comfort.
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.
