Sitting in a car so often, you get to develop some thoughts on how it's all put together. Here's what we think.
- shares

We’re looking at the levels of quality and craftsmanship that go into the Lexus GS F – it’s the kind of attention to detail you might find in a Bentley or even Rolls-Royce, yet this car is priced from just under 160 grand plus on-roads.

This is build quality well above its price tag. Some would even say the full-strength ‘F’ performance models are over-engineered. And, frankly, our long-term GS F is a pretty good example of that. Take the paint and finish, for example.

Paint and finish

Lexus employs a multi-layered process that transforms the way the car looks and how it responds to the sun’s rays. Five coats are applied, and the paint is baked four times. Also, after each coat of foundation paintwork is applied, the car’s exterior is wet-sanded by hand.

The finish is then checked by Takumi craftsmen and digital scanners. No blemishes are missed and the White Nova colour on our long-termer is directly related to the finish on the LFA – the iconic Lexus supercar.

Lexus Takumi

You’re probably wondering what a Takumi is.

They are next-level craftspeople who work across key areas of Lexus manufacturing – and are backed by at least 25 years of training. Think about that for a moment. A quarter of a century of honing their skills on Lexus vehicles.

There are numerous stringent tests, including one that focuses on origami. Aspiring Takumi are challenged to fold an origami cat with their non-dominant hand in under 90 seconds. Among the 7700 workers at the Miyata Lexus plant in Kyushu, just 19 are Takumi rated.

And let’s not forget these exquisite carbon-fibre spoilers – front and rear – they’re beautifully lacquered and made in the same workshop that produced the carbon-fibre trim for the LFA.

Inspection

Regardless of robotic construction and the handcrafted work with the paintwork, Takumi polish and check all Lexus vehicles that come off the production line. This includes monitoring and measuring panel gaps and finish.

Leather and stitching

Takumi craftsmanship is no more evident than when you climb into the GS F’s cabin and lower yourself into the high-backed, and properly low-slung, sports leather seats.

They’re actually a unique foam construction designed to disperse body pressure. And while that might seem like a bit of a sales pitch, I can tell you that after multiple trips, including from Melbourne to Sydney, there’s no stiff back or aching behind as you climb out of this car.

The super-soft leather is perforated for the heating and cooling functions, and then there’s the twin-stitch needlework in contrasting white and blue. And not just on the seats, it’s the same on the leather-wrapped shifter and the steering wheel – and that’s done completely by hand.

Moreover, those who work on Lexus interiors must master a 10-step instruction program at the stitching ‘dojo’. As you know, the term dojo is often applied to a training hall for martial arts.

CAT engine scanning

Just like its Toyota Motor Corp parent, all Lexus vehicles including the hi-po ‘F’ models are built with an inherent level of robustness and reliability – but this engine and pretty much all Lexus powertrains, including the 2UR-GSE 5.0-litre V8 of the GS F, are sent through a CAT scanner to find imperfections that can’t be found by regular external inspections.

The scanner looks for air bubbles and other issues that could cause failures down the track.

Body construction

Even the body construction on the GS F is next-level compared with many rival makes and models.

Lexus uses body adhesive to join body shell panels as opposed to spot welds. Use of adhesive means the bond is formed along the entire surface rather than at specific points. The bond maximises rigidity to deliver a stronger body and better driver control.

The GS range also employs laser screw welding for areas such as the door apertures. Laser screw welding is superior than spot welding in allowing for a narrower centre spacing of each weld, which reduces panel deformation and increases structural integrity.

Chassis bracing

The GS F was developed with new chassis components to increase body structure rigidity and enhance its cornering and straight-line stability. These include highly rigid front and rear body braces (the front brace has a closed-section construction for even greater stiffness), additional front brace attachment points and new rear suspension mounts. And all suspension control arms are also forged in aluminium.

After five months with multiple different drivers, we can honestly say our GS F feels as tight and as well screwed together as it was the day it landed in the CarAdvice garage. There are no squeaks or rattles anywhere, but we would have been disappointed with any less of a result.

Next month, we say goodbye to our GS F long-termer, so stay tuned for a final wrap-up of the go-fast Lexus sedan.
