Ken Block's Gymkhana 8 to feature Dubai Police cars?

Yesterday we showed you the shiny Ford Fiesta that Ken Block will slide, spin, and hoon through the next Gymkhana video. In case the image above isn't clear, that video will drop at midnight EST on February 30th on the Ford Performance YouTube channel. We don't know all the entire premise of the video yet, but this Tweet from the man himself reveals that the video will be set in Dubai. Block is standing on the Fiesta we saw yesterday, and arrayed behind him are a handful of those famous Dubai Police cars you're probably familiar with. The force has a fleet of sportscars and supercars, and the purpose is outreach and goodwill among its citizenry, not necessarily the pursuit of criminals. This content is hosted by a third party.

From left to right, we can see a Maserati GranTurismo, Porsche 911, what looks to be a Nissan GT-R obscured by Block's Fiesta, a McLaren (likely a 650S), Ford Mustang, and a Ferrari 599 of some ilk. Will they take part? Maybe Block will try and run from what might be the most horsepower-intensive police fleet in the world. We'll have answers (and a few minutes of pure Block hooniganism) in a few days. Related Video:

Ferrari patents a fancy and fascinating electric turbocharger

While turbocharging has improved vastly over the years, and it has enabled cars to become both more powerful and more efficient, there's always room for improvement. Turbochargers scavenge exhaust gas pressure and use it to turn a compressor that forces intake air into the cylinders. However, as the patent points out, this means the intake compressor and the exhaust turbine are physically coupled, and have to spin at the same rate. Ferrari's design divorces the two, and it's a happy breakup. The key is hooking up the two components of the turbo to their own individual electric motors, with an energy storage device in between. It's different than the electric supercharger systems you have seen on certain Audi products, for example. Those systems recover energy like a hybrid, store it, and then use it to drive an intake compressor. It supplements conventional turbochargers that harvest energy from the exhaust. In systems like Audi's, the electric supercharger is supplementing the sequential conventional turbochargers when they're not operating efficiently, at very low RPM in particular. It works well, but it's complicated, and it is a workaround for the limitations of a conventional turbocharger. See below for an animation of the Audi system. This content is hosted by a third party.

A smaller compressor generates boost more quickly, but loses efficiency at higher RPM. But there's way more energy in high-RPM exhaust gasses. By hooking up the turbine to an electric motor instead, you can harvest energy from the exhaust throughout the rev range, and particularly when the engine is pushing lots of gasses through. And you can store that energy in a battery if it's not needed at that moment. The intake-side compressor also has a reversible electric motor attached. It is not physically connected to the turbine, so it can operate at any time the computers decide it's beneficial. As engine RPM increases, the compressor doesn't have to increase its speed beyond its optimal range, so there's less energy wasted. And at low RPM situations, when a conventional turbocharger wouldn't have enough exhaust gas passing through its turbine side to generate useful boost in the compressor side, the electric motor can spin up Ferrari's divorced compressor to provide some boost.

Ferrari recalling 85 LaFerraris under two separate campaigns [UPDATE]

Of the recalls we see on a regular basis, million-dollar exotic supercars don't often pop up. But that's exactly what we have on our hands today as Ferrari North America and the National Highway Traffic Safety Administration have issued a pair of recalls for all 85 examples of the flagship LaFerrari hybrid hypercar in the United States. The first of the recall campaigns revolves around the headrests, which "may not absorb the required amount of energy" and therefore fail to comply with the federal safety requirements. The issue involves the larger L32 seat supplied by Lear, fitted as standard for the passenger and optional for the driver's seat. Addressing the issue will require dealers to replace the headrests. The second recall involves the Tire Pressure Monitoring System, which – in the event of a puncture – will display the wrong message. Instead of telling the driver not to proceed on the punctured tire, as apparently required under federal regulations, the system would (as currently programmed) tell the driver to keep driving, but not above 50 miles per hour. Ferrari dealers will need to update the software to fix the problem. These recalls do not represent the first time Ferrari has called in the hybrid hypercar over a potential safety issue. This past March, owners were offered the opportunity to have the fuel tanks replaced. However, unlike these latest campaigns that are being handled in coordination with the NHTSA, Ferrari insisted that the previous fuel tank issue did not constitute a recall. UPDATE: Ferrari North America confirms that no accidents or injuries have been reported to have resulted from either of these issues, which will be addressed in other markets as well - including Canada, where a further 11 units are affected. In order to fix the seat issue, "a small insert will be added to the back of the (large size only) seat headrest." Rectifying both issues "will take approximately an hour of service."

SUMMARY: Ferrari North America, Inc. (FNA) is recalling certain model year 2014-2015 LaFerrari vehicles manufactured May 15, 2014, to March 4, 2015. The affected vehicles have L32 seats as standard equipment for the passenger seat and as optional equipment for the driver seat.
