Engine analysis - Toyota RVX-06

A controversial engine in many ways. In previous seasons the engine has always been a strong point of the Toyota package, but this year it wasn't always so. The TF106 had weaknesses in several areas and the engine was certainly among them. It reportedly lacked top-end power, usually running lower...

Toyota TF106B - front-wing development

In Brazil, a small but interesting change to the endplate, which now features a curving - rather than straight - vertical profile. This increases the width of the 'channel' under the wing profile, in turn raising the quantity of air passing under the wing. This improves the efficiency of the bottom...

Toyota TF106B - front wing T-winglets

For Japan these have grown in size, with an increased cross section and a more curved side profile. This raises the amount of downforce produced with the tradeoff of some added drag. Their effectiveness has been shown in the ability of the Toyota to get the most out of its front tyres on the highly...

Toyota TF106B - rear fences

An interesting development in Japan is the elongation of the vertical fences connecting the rear flip-ups. These elements are now clearly longer than their original version, reaching the level of the winglets just behind the venting chimneys. More a refinement than a major change to the aero set-up,...

Toyota TF106B - sculpted mid wings

After the triple mid wing seen in Hungary, Toyota move to a double for the lower downforce requirements of Turkey. Viewed from above, you can see the sinuous shape of the front mid wing bending rearwards, while the rear one features a delta shape, reminiscent of the wings of the famous Concorde...

Toyota TF106B - turning vanes and winglets

In Hungary the winglets in front of the sidepods have been changed for the third time this season. The vertical endplates are completely different to the previous version introduced at Silverstone, sporting a rounded front edge (blue arrow) to reduce the drag caused by vortices generated between...

Toyota TF106B - front wind development

A heavily revised version for Indy, designed to increase the car's high-speed performance, reportedly one of its weaker points to date. Compared with the previous design, the spoon profile (1) is now wider and slopes down less abruptly than before. The small winglets (2) on the inner edge of the...

Toyota TF106B - sidepod winglets

At Silverstone, these updated winglets in front of the sidepods are a further addition to the revised car introduced at the last round in Monaco. They are larger than previous versions, following a trend set by Honda. This change suits the requirements of the British Grand Prix circuit - medium to...

Toyota TF106 - B version

Monaco saw the introduction of Toyota's TF106B, a deeply revised version of the car that started the season, both mechanically and aerodynamically. One key change is to the front suspension geometry, aimed at improving the way the car works with its Bridgestone tyres (the team struggled to get them...

Toyota TF106 - turning vane development

A very small, but interesting change for Spain, Toyota have doubled up on the small vertical fins placed in front of the horizontal turning vanes that were introduced in Malaysia. The modification aids airflow management in this area, reducing turbulence, but more importantly improving the quality...

Toyota TF106 - wheel rim lip

An imaginative new feature for Europe.A carbon lip is applied to the outer face of the Toyota's rear wheel rims. The aim is to improve brake cooling - using similar principles to those seen on Ferrari's solution at the last round at Imola - while at the same time giving a minor aerodynamic gain by...

Toyota TF106 - front barge boards

An interesting, if minor, aero development spotted on the Toyota in Australia was changes to the barge boards, which sported an additional inner fence in their foremost section. This creates a channel which more effectively diverts the lower portion of the airflow, increasing the efficiency of the...

Toyota TF106 - revised turning vanes

The area of the TF105 illustrated is complex and designed to improve the efficiency of the bottom of the car and hence raise downforce. That additional downforce helps to get heat into the tyres more quickly - not a big issue in Malaysian temperatures, but one that is believed to have troubled the...

Toyota TF106 - new front aero package

These updates are all due to debut in Bahrain. The front wing has revised endplates with an additional side fin (1). On the inner edge of the endplate is another smaller horizontal fin (2), mounted slightly lower than the extra T-winglet (3) on the main profile. Curved winglets (4) on either side of...

Toyota TF106 - side view detail

So far, little has changed over the TF105B. The double vertical fins (1) in front of the rear wheels are still present. These help greatly in the management of airflow towards the rear of the car, dramatically reducing turbulence and improving air extraction from the underbody. The exhaust pipes (2)...

Toyota TF106 - front end detail

So far, little has changed over the TF105B. The front wing sports the same endplates (1) and deep-spoon main profile as on the previous car. The suspension is also the same, with the front, lower wishbones separate, and connected to the lowermost chassis corners (2), in a similar fashion to on the...
