F1: Renault Turbo At Forty - And Fifty

Hard to believe that it's forty years since the Renault F1 team pulled the wraps off the yellow teapot and changed the world of Formula One forever.

The RS01 was the first modern Grand Prix car to make use of the old equivalence rules, which gave engine manufacturers the option of building a three litre normally aspirated engine or a forced induction (turbo or supercharged) one and a half litre engine.

At the time it seemed unlikely that a turbo engine could compete with the all conquering Ford Cosworth DFV or Ferrari 12-cylinder engines. In its first season the Renault engine was notable for its whistling wastegate (a sort of safety valve) and expiring in clouds of white steam. Hence the 'Yellow Teapot' nickname.

It took rivals four years to catch on to the promise of the turbo. When they did they found success much more quickly than Renault. Ferrari won the Constructor's Championship in 1982, its second season with a turbo engine. It would have taken the Driver's Championship too but for the terrible accidents which befell Didier Pironi and Gilles Villeneuve. BMW provided the first turbo engine to take a driver to a Driver's Championship, in 1983, its second season also. lronically Nelson Piquet pipped Renault driver Alain Prost to the title that year.

For Renault it was to be a long wait for the ultimate success - eventually powering five drivers to World Championships six times between 1992 and 1997. With normally-aspirated engines, following the ban placed on turbo engines which had become unfeasibly powerful.

The RS01 was also the first car to race on radial tyres, thanks to a partnership with Michelin. It took rival Good Year until 1984 to realize the game was up for crossply tyres.

In celebration of the fortieth anniversary of its entry to F1, which occurs in July, Renault also presented its vision for F1 in ten years time when it will be celebrating fifty years.

That vision looks quite stunning. But alongside probably the most important Grand Prix car ever, it's an artificial kind of excitement that looks like it belongs in a computer game.

F1: Robert Kubica Impresses In Renault Test Run

The car may be old but its the performance of the driver that's the story here. Robert Kubica returned to F1, after a fashion, earlier this week with an extensive test run in a 2012 Lotus Renault F1 car at Valencia.
The age of the car and the circuit were likely determined by F1's current rules which ban testing, but the reason for Kubica being in the car is far more interesting. Considered by many to be a potential World Champion and certainly one of the fastest drivers of his generation, Kubica's F1 career seemed to be over after a 2011 crash whilst driving in the Rally of Andora. His Skoda Fabia was penetrated by a guardrail in the high speed accident partially severing his right arm.
Up until last year Kubica has been competing in rallying, with the expectation that the limited movement in his repaired arm would prohibit a return to single seater racing.
So this week's test is both interesting and confusing. Interesting because Kubica completed 115 laps of the ret…

Panos Panay's Defence Of Microsoft Surface Hardware Sounds Eerily Familiar

This weekend I went out with my ten year old daughter to select a laptop for her school year beginning in January. The schools requirements are quite specific, requiring a Windows 10 device, with a preference for a touchscreen and a stylus. She chose a Surface Pro, after trying a large number of different options. Having seen the way I use my own Surface Pro - and tried it herself there was only ever going to be two options - and the other was a Surface Laptop.
I tell you this so that you understand I am a buyer of Microsoft's products through choice, not compulsion. I'm on my third Surface device now. 
So when Panos Panay dismissed reports of the death of the Surface hardware line, I was very interested to see exactly how strong these denials were. Especially how they reflect what has gone before. To whit: Windows 10 Mobile.
Panay claimed that Microsoft is in hardware for the long haul. Almost exactly mirroring the words of Terry Myerson, when he claimed Windows Mobile was g…

WhartonBrooks Indiegogo Windows 10 Mobile Even More Doomed To Failure Than Usual

WhartonBrooks is currently crowd-funding its latest Windows Mobile smartphone on Indiegogo. If crowdfunding isn't already a bad enough idea, a company trying to crowdfund a Windows Mobile device should be warning enough for you.
Not that anyone seems to be taking the project too seriously. With a few weeks left to run the campaign has managed to ensnare just 2% of its $1.1m target.
If you want a better indication of how few Window Mobile loyalists remain I doubt there is one. Of 3,900 Windows Phone enthusiasts Wharton Brooks was seeking for its new phone, it has managed to entice just 50.
Windows for Phones is dead, even if the corpse hasn't stopped twitching yet.
