Lexus preparing LFA Tokyo Edition, Supra replacement in the works

Article by Christian Andrei, on September 20, 2011

Lexus’ LFA Tokyo Motor Show Edition will be displayed at the 2011 Japanese show this autumn, together with other new Toyota/Lexus performance cars such as the Supra replacement. The Lexus LFA Tokyo edition features an M3-esque exposed carbon roof and carbon rear spoiler, which is still hydraulically adjustable.

This means that the weave is exposed since the LFA is built from carbonfibre already. It’s expected that the LFA Tokyo would be priced about €40,000 higher than a 'regular' Lexus LFA.

The automaker is planning a spider roadster that with its carbonfibre construction would mean that the open-top LFA is almost as rigid as the coupe, says CarMagazine. But then, sources in Japan said that this project to build a roadster LFA has been scrapped due to the economic uncertainty.

There are reports that Toyota and Lexus are working on new performance cars. It’s believed that Toyota is developing two other performance cars aside from the FT-86 and LFA projects.

Sources say that one is a front-wheel drive car (which is likely to be faster than a CT200h) while the other one will probably succeed the Supra. Lexus has denied that there will be a Supra replacement.

Nonetheless, there are reports that an unofficial project is ongoing for the replacement of the RWD coupe. Sources forecast that this will be launched in 2014. It seems like upcoming fast Toyota/Lexus models will have a change from high-revving naturally aspirated engines like the LFA, ISF and FT-86 to smaller, turbocharged engines.

Serving as the core of the Lexus LFA is a bespoke, naturally aspirated 4,805cc V10 engine that is not only lightweight and compact, but is also a capable performer. The new Lexus LFA is able to develop up to 552bhp of output and up to 480Nm of torque at 6,800rpm, 90 percent of which is available from 3,700rpm. The engine features a red line of 9,000rpm. This new V10 engine features a 72-degree angle between the cylinder heads for an ideal balance for a smoother operation.

Each cylinder comes with individual, electronically controlled throttle bodies for a better throttle response. The V10 engine employs a dry sump lubrication system that enables the block to be positioned deep in the engine bay. This setup lowers the Lexus LFA’s center of gravity and moment of inertia, allowing the V10 engine to manage sustained, high-speed cornering. The high-torque capability of the V10 is attributed to certain elements like high-volume, 12-hole fuel injectors, Dual VVT-i technology, and equal length exhaust manifolds.

With this capability, the new Lexus LFA could accelerate from nil to 62mph in just 3.7 seconds and reach a top speed of 202mph. Its kerb weight of 1,480kg allows the new Lexus LFA to feature a power to weight ratio of 373bhp per ton. The V10 engine of the new Lexus LFA also features a specific output of 115bhp per liter and a high, 12:1 compression ratio, as well as low optimized intake and exhaust flow, and friction internals.

This amount of power is usually available only from larger engine. However, in case of the V10 engine that powers the LFA, it is as compact as a conventional V8 engine and is a light as a regular V6. In addition, the V10 engine is already compliant of Euro 5 emissions standards. This V10 engine was developed in collaboration between Toyota Motor Corporation and Yamaha.
