For this fourth generation Accord Honda made significant engineering design improvements. All Accords sold in North America came with a completely new 2.2 liter 16 valve electronic fuel injected engine standard, replacing the previous 2.0 liter 12-valve model from the past generation. A first in the automotive industry for a non-luxury vehicle was its all aluminum power train (engine and transmission). Also noteworthy, all Accords equipped with automatic transmissions used an electronically controlled rear engine mount to reduce low frequency noise and vibration. The mount contained 2 fluid filled chambers separated by a computer controlled valve. At low engine speeds, fluid routed through the valve damping vibration. Above 850 rpm, fluid routed around the valve making the engine mount stiffer.
In the US, the LX-i and SE-i designations were dropped, being replaced with the DX, LX, and EX trim levels. The Canadian Accord trim levels varied slightly from the US models with LX, EX and EX-R roughly corresponding to the American DX, LX, and EX, respectively. Fourth generation EXi Accords sold in Australia and New Zealand offered the same
4-wheel steering technology as was available optionally on the US Honda Prelude. US Accord Coupes were available in DX and EX trims (LX and EX-R in Canada).
A 125 horsepower (93 kW) 4-cylinder engine was offered the DX and LX models (F22A1), while the 1990 and 1991 EX received a 130 hp (97 kW) version (F22A4) and the 1992 and 1993 received a 135 hp (100 kW) version (F22A6). Cruise control was dropped from the DX sedan, with air conditioning remaining a dealer-installed option. The LX kept the same features as the previous generation including air conditioning, power windows, locks, and mirrors. The EX added 5 horsepower more due to different exhaust manifold and slightly bigger exhaust piping, 15 inch machined aluminum-alloy wheels, sunroof, upgraded upholstery, dual-outlet single exhaust, rear stabilizer bar and a high-power 4-speaker stereo cassette. The EX also had an optional
anti-lock braking system (at the time abbreviated as ALB, now all automakers refer to it as ABS).
