2017 Lexus Lc 500 Review
Beyond its styling and impactful performance, the new Lexus LC 500 serves as a symbol of the achievement that can result from heightened collaboration between design and engineering groups and their commitment to help overcome each other’s hurdles. When Akio Toyoda challenged these development groups to produce this special car, it meant surpassing many manufacturing, design, material, and dynamic obstacles that could typically compromise a vehicle’s targets or design vision.
The LC 500 was driven by a strong, appealing fundamental design target (LF-LC), and engineering teams worked tirelessly to find new solutions to maintain as much of the concept in the production car as possible. Likewise, vehicle designers were very involved from the earliest stages of the dynamic development process to understand the engineering targets and collaborate with design viewpoints and potential solutions.
“Design and engineering sides worked together on issues and obstacles that were overcome one by one. I feel we achieved something greater than simply preserving the spirit of the concept’s design,” said Chief Engineer Koji Sato.
At first glance, it becomes apparent that the engineering and design team’s collaboration was highly successful, considering how much of the LF-LC’s design ideology the team was able to transfer into the new LC 500. The new production model shares many of the key design elements, proportions and visual dynamism of the concept car that inspired it. The Lexus LC 500’s visual appeal is defined by an athletic aerodynamic shape. It features sensual curves, emotional forms, an available flowing carbon-fiber roof (glass roof standard), helping create a low, wide imposing stance that comes together for a highly functional, passionate package.
Internally, Lexus engineers referred to this menu of mass-arranging tactics as the “inertia spec.” The driver hip and heel points have been lowered, wheels have been pushed to the corners of the car with shortened overhangs, and the drivetrain mass has been located behind the front axle line to create a front mid-ship layout. The LC 500 also relies on run-flat tires to improve packaging, reduce weight (thanks to no spare), and help shorten overhangs to achieve dynamic targets. The 12-volt battery has been relocated to the trunk as part of the mission to redistribute weight.
The power delivery to the rear wheels for Lexus LC 500 is handled by a new, very well matched set of components that maximize output to the wheels. The heart of the new LC 500 is derived from the proven, high-revving 5.0-liter V8 that is found in the RC F and GS F. The naturally aspirated V8 was selected for its smooth, linear throttle response and emotional engine sound. The all-aluminum, 32-valve V8’s output targets 467 HP and 389 lb.-ft. of torque.
The new engine is built for durability with lightweight, high-strength forged connecting rods and titanium valves that allow the engine to flourish at high rpm. This naturally aspirated engine makes an ideal pairing to a balanced sports coupe with its linear power delivery that allows easier control and exhilaration behind the wheel.
The engine in the Lexus LC 500 uses a dual intake inlet that help improve breathing and allow the engine to produce its fantastic sound. The new coupe features an active exhaust that opens baffles in Sport mode to help give the car a more aggressive exhaust note even in start-up. In fact, even when the vehicle is in Normal mode the exhaust baffles open above 3500 rpm. During acceleration, a Sound Generator involving tuned acoustic plumbing enhances the engine’s raucous melody into an aural thunder that helps distinguish the LC 500 in its competitive segment.
