McLaren P1 squares off against Porsche 918 in Evo track battle

Evo's side-by-side comparison of the McLaren P1 against the Porsche 918 Spyder isn't the first time we've seen England and Germany's ultimate automotive weapons sized up together; last month, Autocar tested them over the standing mile, with a Ducati 1199 Superleggera playing the joker. Evo throws a few curves at its test, though, taking the supercars to Anglesey Circuit in Wales to see which will lay down the fastest lap time with scribe Jethro Bovington at the wheel. In case the numbers haven't yet been seared into your memory, while both are assisted by electric motors, the 3,069-pound, rear-wheel drive P1 gets on with 903 horsepower and 664 pound-feet from a 3.8-liter, twin-turbocharged V8. The 3,750-pound, all-wheel-drive 918 Spyder does its job with 795 hp and 575 lb-ft surging out of a naturally aspirated, 4.6-liter V8. We're not told know which circuit layout he uses for the test, but both cars comfortably eclipse the mark set by the fastest coupe Evo's driven around it so far, the Ferrari 458 Speciale. Then, in an epilogue occasioned by a tire change, one of the supercars comfortably eclipses its own time again, before Bovington declares one the master of the track and the other the ruler of the street. Enjoy finding out which is which in the video above.

Porsche offers design walkthrough of Panamera Sport Turismo

The Porsche Panamera Sport Turismo was arguably the best concept car of 2012, and Porsche has been building upon that momentum by teasing us with videos of its first-ever station wagon design. After showing us some driving shots of the Sport Turismo, Porsche released a more in-depth and behind-the-scenes look at what it took to take the Panamera shooting brake from a full-scale clay model to the final product we saw on stage at the Paris Motor Show. In the video, Michael Mauer, Porsche style director, and Mitja Borkert, general manager advanced design style, both give a little insight about what went into creating the Sport Turismo Concept.
More than just a station wagon version of the Panamera, the Sport Turismo has a totally distinctive look nose to tail. Some of the key elements the designers touch on in the video include the Porsche-signature raised front fenders, the wide rear shoulders, the front wing inspired by the 918 Spyder, and even some of the car's unique touches, including the headlights and the three-dimensional "Porsche" lettering across the liftgate made from glass. One of the more exciting aspects of the concept - which is sadly just glossed over in the video - is the rear liftgate spoiler that features "variable aerodynamics" that sounds like it acts similar to the retractable spoiler on the current Panamera.
We still don't know if the Panamera Sport Turismo will make it into production, but if you want to see what went into creating this exciting concept car and see the different build phases designers went through to create the Paris show car, check out the video by scrolling below.

Porsche 911 GT3 RS looks wicked, this way comes

Those who didn't think Porsche went extreme enough with the latest 911 GT3 likely won't be disappointed when the more focused GT3 RS arrives. And as you can see from these latest spy shots, it looks like it's speeding right around the corner. Tipped to debut at the Geneva Motor Show this coming March, the new Porsche 911 GT3 RS is shaping up to be an enthusiast's dream - and with the prospect of a GT2 in doubt, could be the most hardcore Elfen in the range. Instead of the 3.8-liter flat-six in the current GT3, the new RS will pick up where the previous limited-edition GT3 RS 4.0 left off, with four naturally aspirated liters of unadulterated boxer power channeling a good 520 horses to the rear wheels. That will be a significant increase over the existing 475-hp GT3 and will match the 911 Turbo for output (if not the 560-hp Turbo S) and without any turbo lag to slow down the action, either. Whether it will keep the GT3's dual-clutch gearbox and four-wheel steering system, or ditch one or both for a more analog approach, remains to be seen, but we're holding out hope. Either way, the modifications to the bodywork ought to make the GT3 RS stand out even further and stay glued to the race track it will call home. Notice the deep front splitter scooping up snowflakes like a shovel, a massive rear wing (which may or may not be the final production version), the Turbo-spec rear end with air intakes ahead of the rear wheels, and a set of awesome-looking gills over the front wheels – all of which you can scope out in the gallery full of spy shots above.
