Formula E gets wireless-charging BMW i8 safety car [w/video]

Racing series typically select a safety car appropriate to the kinds of racecars for which they'll be setting the pace. So you might find a Mercedes SLS pacing a Formula One grand prix, for example, and you're more likely to find a BMW M4 on duty at a DTM race and a Chevy Camaro or SS on an oval speedway for a NASCAR or Indy race. It would only stand to reason, then, that the FIA Formula E Championship kicking off next month in Beijing would press a plug-in into service as its safety car. But the organizers didn't go for your run-of-the-mill Nissan Leaf or Toyota Prius.
No, the safety car for Formula E will be a BMW i8 specially modified for the occasion. As you can see from the video below, the hybrid sports car packs a full roll cage, racing buckets with harnesses, special communications systems and on-board fire extinguishers. But that's not all.
In partnership with technological partner Qualcomm, the Formula E support fleet - including two examples each of the i8 and i3 - will feature inductive charging. So while one is out on the track, or at least sitting at the end of the pit lane waiting to be deployed - the other will be charging wirelessly. The vehicles are still pending FIA approval, and only one has been outfitted with the Qualcomm Halo wireless charging system (with the others to be retrofitted later), but they were all on hand for the recent practice race at Donnington Park.

BMW reveals M4 safety car with innovating water injection system [w/video]

Racing series don't just pick their safety cars at random, or use just whatever car is lying around. These days the car that sets the pace at the front of the pack is typically provided through consideration by a sponsor. In the MotoGP series, that's BMW and its M division, which have served up the Official Car of MotoGP since 1999. What you're looking at is the latest, and it packs some innovative technology on board. Aside from the matte black wrap with BMW's iconic striped livery, upgraded aero kit, retrofitted interior and emergency equipment, this BMW M4 coupe packs a new injection system under the hood. Only instead of injecting fuel, it injects water into the combustion chamber – something that wouldn't usually be recommended, but BMW insists actually aids in the combustion process. The idea is that the temperature of the air being mixed with the fuel inside the engine is usually hotter than ideal, so the system injects a fine mist of water into the collector in order to reduce the air's temperature... sort of like one of those hydrating misters at an amusement park or outdoor mall, but in an even hotter environment. The system brings the temperature of the air down to a more optimal temperature, helping it combust better. The process is said to yield a number of positive effects. For one, it reduces knocking. For another, it can make more out of lower-octane fuel where higher octane isn't available. It also can control the adverse effects of higher ambient temperature on the combustion process. But most of all, it increases output and reduce fuel consumption by around eight percent. Whether that eight percent is worth the added weight of the system – particularly with water pump and a 1.3-gallon tank in the trunk – is up for debate. But we'd imagine that the Bavarian engineers have weighed very carefully. Of course there's also the matter of refilling the water tank, which BMW says would be carried out whenever the safety car is refueled, but in real-world conditions would only necessitate attention once every five top-ups at the gas station. By now you might have guessed that BMW probably didn't develop this system just for the MotoGP safety car, and isn't planning on keeping it confined to the racetrack. Instead it's being tested and demonstrated on the safety car before being rolled out on production models in the future.

BMW revisits its 8 Series

So why would BMW choose July 2 to release a retrospective on the 8 Series? Could it have something to do with the recent unveiling of the Pininfarina Gran Lusso Coupe concept, another sleek, B-pillarless V12 two-door, at this year's Villa d'Este? We have no idea, but the timing is likely coincidental.
This three-minute look at the 8 Series talks to Niels Hamann, who was smitten with the long-hooded coupe when it appeared in 1989 and finally bought one in 2004. Hamann also happens to be a project manager at BMW, and that came in handy when he wrote a book detailing every aspect of what was BMW's flagship for ten years but to the chagrin of many only managed one generation.
While we wait for the next clue about the Gran Lusso - 8 Series connection, check out the video below.
