The Model Was Launched In 1968

Audi AG (Audi) is a German automobile brand founded in 1909 by August Horst. Audi, Horch (an earlier automobile brand founded by August Horst in 1899), Wanderer and DKW merged into Auto Union AG in 1932. The four ring Audi emblem represents these four companies. At the end of World War II the Auto Union factories were taken over by the Soviet Union who occupied the eastern part of Germany. Auto Union GmbH was restarted in Bavaria, in the western part of Germany, in 1949 and produced cars, delivery vans and motorcycles under the DKW brand, all with two-stroke engines. The Quattro four-wheel drive system, a development from systems used in the DKW Munga and the Volkswagen Iltis, both small four-wheel drive military vehicles, was introduced in the 1980 performance car Audi Quattro, a coupe with constant four-wheel drive. The Quattro four-wheel drive system was later implemented to the other models in the Audi range.


The lightweight lower suspension arms are aluminum for reduced suspension inertia, the front hub carriers are steel, and all Accord trims use a tubular front stabilizer bar with bonded mounts for smoother functionality. Specially calibrated geometry ensures a high degree of quickness and precision, smoothness and stability. Accord's new multi-link rear suspension includes stamped-steel arms, cast-aluminum hub carriers and a stabilizer bar. Mounted on a floating type steel subframe, the rear suspension provides agile handling, both during normal driving and in emergency maneuvers, together with a flat ride. The trailing arms are located on the unibody via hydraulic compliance bushings for exceptional control of noise, vibration and harshness NVH while maintaining precise handling. All Accord trims use a solid rear stabilizer bar for crisp turn-in and body roll control. The compact design of the rear suspension also facilitates a more spacious trunk design. A first for Accord, the Electric Power Steering (EPS) incorporates dual pinion gears and a variable gear ratio for steering feel, performance and comfort that is unsurpassed in the class.


Compared to a traditional single-pinion steering system, the dual pinion EPS utilizes the physical steering input from the driver as well as from a supplemental electric motor. A non-contact torque sensor measures the driver's steering effort and an ECU determines how much electric motor assist to apply, resulting in smooth, natural and precise steering feel. The steering ratio is variable with a final full off-center ratio of 11.8:1. This provides a quick 2.3 turns lock-to-lock (compared to 2.5 on the previous model), enabling confident, precise steering control and easy low-speed maneuverability. The EPS on the Sport trim is further tuned to provide more information from the front tires for a more secure and precise enthusiast-oriented feel. In another first for Accord, the Straight Driving Assist function reduces the steering effort required when driving on a sloped or crowned road. When the Straight Driving Assist system detects that steering effort is being applied to keep the car driving along a slope, the Electric Power Steering system applies motor assist. This reduces the muscle effort required to maintain the desired direction on the sloped road to the same level as is required on a flat road.


4-wheel disc brakes with 4-channel (ABS), Electronic Brake Booster (EBB), Electronic Brake force Distribution (EBD) and Brake Assist are standard equipment on all 2018 Accords. The system utilizes a large-diameter master cylinder to achieve a short-travel, firm pedal. The EBB uses an electronic servomotor to assist braking performance while improving brake feel and pedal modulation in virtually all conditions. The result is a comfortable and refined braking feel at low speeds, predictable and easy operation on the highway, a sporty feel on winding roads, and reassuring high-performance stopping in emergency situations. The ventilated front brakes rotors are clamped by single-piston brake calipers. The rear disc brakes incorporate solid rotors, likewise paired with single-piston brake calipers. The low-friction design of the brake calipers reduces energy losses when the brakes are not in use, directly improving fuel efficiency. VSA also provides a limited-slip differential effect for the driving wheels by applying braking force to a slipping wheel, thereby redirecting driving force to the wheel with more traction. While the driver can reduce the traction control effectiveness allowing more wheel slip during stuck conditions by pressing the VSA button, ABS remains fully operational at all times.
