SUMMARY OF HONDA ACCORD
The 2010 Honda Accord Crosstour leverages the
benefits of a premium chassis design for rewarding and sophisticated handling
dynamics. A double-wishbone front suspension and multi-link rear suspension
allow for both a smooth ride and world-class levels of performance that is
equally at home on a curvy road, long stretches of interstate highway or in
inclement weather. Ground clearance of 6.0 inches enhances capability in snowy
conditions and broadens access to more roads off the beaten path. Standard
features include Vehicle Stability Assist™ (VSA™), commonly referred to as
Electronic Stability Control; 4-wheel disc brakes; and stabilizer bars front
and rear.

- · Front and rear stabilizer bars
Front
Subframe
A front "floating" subframe design is used on the Accord Crosstour. A welded-steel subframe secured to the unit body's longitudinal rails supports the Accord's engine, transaxle, transfer case, steering gear and front suspension. The front of the subframe assembly is designed for enhanced stiffness with minimal weight penalties and uses four tuned rubber mounts to isolate the subframe from the main body structure, i.e. it is "floating."

A stiffener located under each subframe attachment
fastener helps to further stabilize the assembly, thereby achieving linear
handling and braking performance. The subframe includes two Active Control
Engine Mounts (ACM) that counteract the inherent vibration created by the
Variable Cylinder Management (VCM) system, plus one rubber isolator
transmission mount. (See the body section for more details on ACM). The
"floating" mounts are strategically positioned to counteract noise
and vibration while reducing the transmission of engine noise and vibration to
the passenger compartment.
Double
Wishbone Front Suspension
Widely spaced upper and lower wishbones give precise suspension action, with the coil-over spring and shock absorber units free of the binding caused by the side-loading inherent in some less sophisticated strut-type designs. The Accord Crosstour's front suspension is a modified version of the double-wishbone system used on the Accord Sedan and Coupe. Stabilizer bars, springs and damping rates have been optimized to provide the best combination of ride and handling. The front lower control arms are forged steel and connect to a stamped steel box-section sub frame. The stamped-steel upper control arms connect to a forged-steel knuckle.

Progressive valve nitrogen gas-filled coil-over
shock absorbers integrate an internal rebound spring. When cornering, the
internal rebound spring allows the shock absorber to exert additional force on
the inside wheel's coil spring to help counteract wheel lift in certain
situations. This premium shock absorber design helps to improve both ride
comfort and responsiveness. Ultimately, tire-to-road adhesion is enhanced.

Rear
Subframe
The rear subframe, which supports most of the rear suspension and the rear axle drive unit, is made of high-strength steel for high stiffness and minimal weight. The shape of the rear subframe is equally important - it must accommodate the drivetrain components for the available Real Time 4WD system and the multi-link rear suspension. For excellent ride and handling characteristics, the subframe attaches to the unit body at four widely spaced, rubber-isolated, mounting points. Rear-suspension components, especially the springs and shock absorbers, are as compact as possible to facilitate a wide, flat, load floor and to leave room for both a spare tire and a fuel tank. The rear axle drive unit (if equipped) is mounted to the subframe by means of rubber isolators to block powertrain noise and vibration from the passenger compartment.

Multi-link
Rear Suspension
The Accord Crosstour's rear suspension is a compact, multi-link layout for excellent ride and handling, minimum weight and optimum packaging. Wheel travel is a generous 4.3 inches in compression and 3.7-inches in rebound. The three links that position each rear wheel laterally run between the knuckle assembly and the subframe. Progressive valve nitrogen gas-charged shock absorbers attach from a low point on each knuckle to a highly rigid attachment point on the unit body.

The knuckles are an "in-wheel" design to
optimize suspension geometry and packaging efficiency. Bushing compliance
provides a modest toe-in effect in response to substantial cornering and
braking loads to enhance overall stability. The rear knuckles are made from
aluminum and help to reduce unsprung weight for quick suspension
responsiveness. Optimized high rigidity bearings accommodate the additional
forces of the four-wheel-drive system. Coil springs, dampers and a stabilizer
bar are tuned for the best combination of ride and handling. Rear subframe
mounts and lateral control link bushing rates were adjusted to create a
discrete level of lateral force steer at the rear axle.
