The Lexus LFA supercar – the long production version arrives

The see through model of the Lexus LFA on in the ‘art gallery’ at the Tokyo Show

It’s been a time coming. The Lexus LFA first appeared as a concept car at the Detroit Auto Show is production ready. Lexus the announcement at the 2009 Tokyo Show where a prototype of the car was on display along with a see through model in the company’s gallery” – and the stunning V10 supercar is indeed worthy of a in an art gallery, although keen will still have to a bit more of a wait since the car expected to reach garages early 2011, with 500 units being produced.

To achieve the car’s 2.64 power-to-weight ratio Lexus has to keep the LFA’s weight to a of 1,480 kg (3,263 lbs) thanks to the rigid carbon reinforced plastic cabin at the core, which is approximately 100 kg lbs) lighter than a aluminum unit.

With the being the heaviest component in a Lexus has also made a reduction in the overall weight of the LFA by the engine’s mass. By using such as aluminum, titanium and the LFA’s V10 engine manages to a profile smaller than of a conventional V8 without sacrificing Assisted by a 12:1compression ratio, low internals and optimized airflow, the LFA an output-per liter of 85.7 (117 PS/L).

Critical to the car’s performance is not how much it weighs, but also that weight is placed. To ensure a low moment of inertia means less effort is to turn the vehicle Lexus has the heaviest components, such as the engine and fuel tank, the wheelbase so they are closer to the center of gravity.

The oil and water are mounted down and towards the of the engine to reduce the amount of of the front wheels, while the the second heaviest component in the is positioned directly on the rear

Lexus says the front-mounted and rear-mounted transaxle configuration the LFA a 48:52 front/rear weight that combines the controllability and stability of a front engine wheel drive (FR) with the cornering performance of a mid rear wheel drive platform, but with exceptional ability.

The LFA’s handling is assisted by its low of gravity, which Lexus is lower than that of a sports car”. The vehicle’s dry lubrication system employs a oil sump, which allows the to be moved closer to the ground, the low floor, with a minimum clearance of 115 mm (4.5-in), also to the low center of gravity.

The driver as close as possible to this of gravity. The drivers seat between the front and rear and, thanks to vertically exhaust pipes closer, the center tunnel also a position closed to the center.

Lexus has replaced the conventional throttle body with electronically controlled throttle that dramatically enhance efficiency by creating a minimal of air between each throttle and its respective combustion chamber. effectively halves engine time, with the response of the LFA so that when the accelerator is the revs drop too quickly for a analog tachometer needle to up. Therefore, Lexus has used a TFT LCD panel graphical tachometer features a rev peak-hold function, lap and a variable redline display.

The shifters of the LFA have been so that the force required to them varies between and downshifting, with the downshifting requiring a greater degree of than the upshifting paddle. like a good idea could provide an extra of differentiation between upshifting and Lexus also says downshift paddle has a higher pull to foster a sense of upon each downshift.“

To provide consistent and effective under any conditions the LFA employs an controlled braking (ECB) Conventional brake systems use from the engine to control a booster that multiplies the own brake effort. However, means that overall performance and effectiveness will depending on the amount of engine present at the time.

In comparison the ECB system uses an electric to generate hydrologic pressure, providing consistent braking without relying on engine

The state-of-the-art components extend to the remote-reservoir monotube shock developed exclusively for the LFA to deliver and precise damping. Their rods are coated in a Diamond-Like (DLC) compound and the main walls are Ni-Si plated. The reservoir cylinders employ bellows (expanding and contracting connected to the main cylinder via valves.

Lexus has sought to refine aspect of the LFA – right down to the of the engine, which it likens to a tuned musical instrument. In the resonant frequency of the surge has even been tuned to a intake harmony to give the LFA its note. Unfortunately only a few will get to enjoy such a in person – Lexus only be producing 500 of the cars and will attract an asking of US$375,000.

As expensive as that apparently Lexus expects to a loss on each one.
