At the European GP in Valencia we saw the unusual circumstance of two ‘leading’ cars both retire within a few laps of each with a related fault. It was confirmed by Renault that there were alternator failures on the Renault Engines of Vettel’s Red Bull and Grosjean’s Lotus. Typically the alternator in a Modern F1 car is unseen and causes almost no issues, so this is an opportunity to look at this component and the failures in Valencia.
In conjunction with the Motorsport Industry Association (MIA), and National Motorsport Week 2012, M-Sport – the company behind Ford’s assault on the World Rally Championship (WRC) since 1997 – will open its doors for students to attend a unique engineering seminar on Monday 2 July.

Such is the pace of development, Lotus had made at least two changes from the specification I described in my last analysis of the Lotus E20.
The teams have further modified the front wing with a revised cascade winglet and the sidepod fronts have reverted to an old shape without the peaked visor below the sidepod inlet.

Over the past three races Mercedes have produced a near “B” spec car, with a new gearbox\rear suspension, new sidepods and a new nose. The cars specification was also altered to suit the low drag demands of Montreal with a shallower rear wing and modified front wing.
Part 3 of the Tech files is now available on GoCar.gr, covering the basics of the Front Wing; Multiple Elements, Cascades, Endplates, Flexing and DDRS
Every year High Power Media, who publish ‘Race Engine Technology’ (RET) Magazine, produce a number of magazine format Race Technology Reports. Covering F1, Moto-GP, Nascar, Drag racing and 24-hour racing.
Just out is the current F1 Race Technology issue, covering Technical subjects from 2011 and 2012.
Coming straight after another Technical Directive from the FIA, Red Bull have again had one of their designs ruled on by Charlie Whiting. It’s now the Front hub design that has stretched the rules to the point where a clarification was required. Uniquely Red Bull duct air through the front hub to vent it out through the wheel for aerodynamic benefit. This appears to contravene the regulations on air ducts forming part of the brake system.
