OREANDA-NEWS. February 23, 2016. Heralding a new generation of more engaging and responsive vehicles, the new LC 500h has been designed to offer customers a significantly sharper, more refined driving experience. It combines the superior ride quality befitting a flagship luxury sports coupe with an engaging, dynamic drive and a depth of character unlike that of any previous Lexus.

The LC 500h is the first Lexus to benefit from the company's all-new, premium rear-wheel drive platform; part of a new corporate global architecture for luxury vehicles (GA-L). The underpinnings of this new coupe will become the blueprint for future front-engine/rear-wheel drive Lexus models.

Platform design is fundamental to dynamic handling characteristics. At the outset, Lexus engineers focused on what they refer to as the LC 500h's 'inertia specification', placing most of the vehicle mass, including the engine and occupants, as low and centralised as possible within the chassis.

The powertrain mass is located behind the front axle line creating a "front mid-ship" layout while very short front and rear overhangs push the large diameter tyres to the vehicle extremities. The wheels are shod with run-flat tyres that eliminate the weight and weight-distribution penalty of a full-size spare tire, while driver hip and heel points have been substantially lowered.

The centre of gravity has been further lowered by the introduction of numerous technical innovations which reduce the body weight of the LC 500h. These include aluminium front hood and fenders, aluminium door skins mounted on a carbon fibre structure, a carbon and glass composite boot lid, aluminium front suspension towers, ultra-compact LED headlamps, available forged alloy wheels and carbon fibre roof.

The extensive use of strategically located high-tensile steel body structures reduces weight, improves weight-distribution and increases body rigidity, all of which promote consistent, predictable handling behaviour and sharper steering responses.

Particular attention has been paid to the development of the LC 500h's multi-link front suspension system, adopted to allow for the vehicle's large diameter wheels while at the same time accommodating a very low bonnet line.

The system features two upper and two lower control arms, with double ball joints on each arm. This arrangement optimises suspension geometry to facilitate precise control from driver inputs and road conditions, creating a more precise steering response.

Optimising the sharpness in both steering and suspension movement, sprung weight has been reduced as much as possible through the extensive use of lightweight, forged aluminium componentry. And the system demonstrates exceptional rigidity under lateral g loading.

In combination, these chassis and suspension development measures offer an entirely natural, non-taxing driving experience which combines sharp responses, exceptional handing balance and straight line stability with the ride comfort appropriate to a Lexus flagship coupe.
