Bonneville broadcast will add pepper to the salt

If you've ever been to Bonneville during Speed Week, you know what a thrilling corner of the motorsports world the place occupies: standing out on the endless, blazing-white expanse of salt, hearing the cars before you see them, seeing first the roostertail of salt rocketed into the air, then the tallest part of the rear fin, then the car itself, blasting over the curvature of the Earth, followed by engine cutoff, popping chutes, deceleration and the giddy celebration of driver and crew as yet another record falls. But most people -- those with jobs, kids, responsibilities (where are your priorities, people???) -- will never get a chance to go. So this year, the Southern California Timing Association has made a deal to broadcast audio of the entire Speed Week live, as it happens, direct from the salt, on the fabulous internet.

Toyota Prius Plug-In is practically perfect in London

Toyota Prius Plug-in - perfect London transport We though we ought to do Toyota the courtesy of a non-disparaging headline after the first interim results of trials of the Prius Plug-in in the hands of drivers in London have turned out to be very positive. Toyota and EDF Energy have supplied – on lease – 20 plug-in hybrids (PHEV) to London businesses and organisations (no Joe Public on this trial) to get some real-world feedback on usage, journey distance and recharging patterns. For those of you who don’t remember, the Toyota Prius Plug-in is a regular 3rd Gen Prius but with a length of flex and a set of lithium-ion batteries that allows users to grab some charge from the mains and to drive further in EV mode – up to 12.5 miles in perfect conditions.
