California adapts ZEV mandate with PHEVs for smaller automakers

California is the nation's largest market for zero-emissions vehicles with over 100,000 of them estimated to be on the roads there. The state's goal is to keep that number growing every year. To that end, the California Air Resources Board is now tweaking its rules in a way that might not boost ZEVs but could mean more plug-in hybrids for the Golden State. Jaguar Land Rover, Mazda, Mitsubishi, Subaru, and Volvo asked for an exemption to the state's zero-emissions vehicle mandate last year due to their relatively small development budgets compared to larger automakers. CARB denied their request but did craft a compromise, according to Automotive News. Rather than being required to offer a ZEV in the state, companies with an annual global revenue of less than $40 billion, like those in this group, may instead sell plug-in hybrids to earn ZEV credits. The companies aren't completely off the hook, though. If these plug-in hybrids don't earn enough credits, the corporations must buy them on the market to make up the difference. Automakers with popular electric models like Nissan and Tesla have made a big business through this trading system by selling their surplus to rivals. Tesla alone pocketed $51 million in the first quarter from this part of its business, according to Automotive News. The changes to the regulations also aren't set in stone, yet. CARB is meeting in 2016 and could adjust things further at that time.

Watch new Jaguar XF perform a literal high-wire act

Coming out with a new luxury sedan can be a truly daunting prospect. Make it too edgy and you'll risk disenfranchising what can often be a rather conservative customer base. Make it too conservative and you may fail to attract enough new customers or generate enough interest to make the endeavor worthwhile. Whether Jaguar succeeded in walking that thin line with the new XF is a matter of personal taste, blending as it does elements from the smaller XE and the outgoing XF it replaces. But in launching the new model, Jaguar didn't just pull of a figurative high-wire act – it did quite a literal one. To drum up support for its newest debut, Jaguar undertook the stunt depicted in the video above, stringing a pair of carbon-fiber cables some 60 feet above the River Thames in London. With some guide wires and counterbalance weights to keep it all in check, and a motion-picture stunt crew orchestrating it all, the new XF drove over 780 feet from one bank of the river to the other, setting a new world record in the process. Instead of thinking too hard about the whys (seriously, though... why?) and hows, we suggest you just watch the video above. Related Video:

Are you the Jaguar F-Type Coupe R-S?

It's no secret that Jaguar is working on a fixed-roof version of the F-Type roadster, but now it looks like it's also developing a high-performance model for said coupe. Captured sharpening its claws at the Nürburgring, this F-Type Coupe prototype could very well be an R-S or even a more track-ready R-S GT variant.
Our biggest clue suggesting the latter are its massive brake rotors with bright-yellow calipers - similar pieces are also found on the recently introduced XKR-S GT. This would make sense, since a report in May said that Jaguar is looking to create a full line of R-S GT models in a similar fashion as the Mercedes-Benz AMG Black Series. Missing from this prototype, though, are the telltale aero add-ons we seen on the XKR-S GT - go-faster bits like the latter's front fascia winglets and rear wing, though this model is obviously still being developed. Regardless of what this new grippier, quicker kitty is called, we say "Yes, please."
