Another Ayrton Senna Honda NSX for sale

Ayrton Senna’s Honda NSX (pictured) is expected to fetch £75-85k Ayrton Senna was arguably the greatest F1 driver of all time, and his death 20 years ago at Imola sent shock waves through the sport and deprived F1 fans of more years of Senna’s driving prowess. But driving F1 cars wasn’t the only thing Senna did; just like today’s F1 drivers he was also involved in road car development, and during his time with McLaren he was a part of Honda’s (engine suppliers at the time for McLaren) development of the original NSX. So any Honda NSX with a clear link to Senna can reasonably expect to be a desirable car for collectors and F1 fans to acquire, and the Honda NSX up for grabs at Silverstone Auctions’ sale next month has a very clear Senna link.

Mercedes-Benz Bionic car at MoMA

Despite its unusual-looking shape, the fish is extremely aerodynamic and can therefore move using a minimal amount of energy.

rusEFI: Open-source homebuilt fuel-injection set to rival Megasquirt

Electronic fuel-delivery and ignition controls have given us a new golden age of engine efficiency and performance. Most of us would never go back to the dark ages—say, before 1990—when you could still buy new vehicles with carburetors and clunky distributors. From the point of view of those of us who like to modify our cars, however, the black-box nature of engine-control computers limits our options for making changes to how our fuel-delivery and ignition systems function.
