New Lexus GS to Ditch Separate Chassis and Gain Turbocharging?
Building SUVs on ladder chassis is as old as the first SUVs themselves, with all manufacturers adopting the technique for their products at some point. Despite the trend to ditch the ladder chassis in recent years, some makers have stuck with it, explaining that its simplicity and strength were what kept this rather ancient way of building cars still viable.

Many manufacturers, like Mitsubishi, GM and even Land Rover with the Defender are still using this technique, which basically amounts to the chassis being built separately, with the body of the car getting lowered onto the chassis which already has wheels, engine and everything else, you connect up a couple of wires and cables, tighten a few bolts, and voila!

The current Lexus GX is based on the Toyota 4Runner, or rather an evolution of that car, with a different badge and a few toys thrown in to keep people from not noticing its roots. Apparently, Toyota are planning on ditching the body-on-frame set-up, in favor of a more modern, unibody construction, a technique which means basically means that the chassis and the body are one, currently used on practically all cars ranging from the smallest to the largest, and most importantly for the GX, its smaller brother, the RX, a car on which the next GX could be based.

Apart from the change in its construction, the GX may also get a fuel-efficient four-pot turbo unit, if Toyota deem it necessary to replace their 3.5-liter V6. However, since the V6 is very appreciated in the US, the move to turbo power may not be particularly close, despite Lexus possibly adopting it for their more mainstream offerings, to claw back some market share from the Germans.
