VW internal investigation finds 'no evidence' against suspended engineers

Volkswagen is still working out the chain of events that led to emissions-evading software being installed in 11 million diesel vehicles worldwide and deciding who was responsible for the treachery. So far, the German automotive giant's internal investigation hasn't publicly named many suspects, and three suspended executive-level engineers have been found not to be culpable in the wrongdoing, according to an anonymous insider speaking to Reuters. VW knows that the software began being installed in the EA 189 engine in 2008. The internal investigation has found that the emissions-evading tech was created because the powerplant was found to fail US standards. Plus, the diesel mill wasn't meeting cost targets, according to Reuters. The automaker responded by suspending over 10 employees, but three top engineers among them might not have been involved. Those put on leave include Heinz-Jakob Neusser from VW, Ulrich Hackenberg from Audi, and Wolfgang Hatz who led Porsche's research and group-wide engine development. The internal detective work hasn't turned up any evidence against these three men. In addition to VW's own inquires, government investigators in both the US and Germany are taking a serious look into the company's actions, too. So far, the automaker is setting aside about $7.3 billion to pay to fix the vehicles with the evasive software. Depending on what authorities find, the costs could grow quickly. Beyond the financial implications, the scandal has led to a serious shakeup in VW's corporate structure. Related Video:

Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.

2016 Porsche Cayman GT4 First Drive [w/video]

The 2016 Cayman GT4 is the sort of Porsche that purists fear would eclipse the rear-engined 911. The balance inherent in the mid-engined layout of the rigid Cayman chassis meant that it was only the right combination of horsepower and suspension away from whupping a comparable Carrera. Porsche has been very careful to keep this Cayman from doing that, despite the GT4's improvements. If you think this means the GT4 has been hobbled or hamstrung, it hasn't. Even a sopping wet track at Road Atlanta in Georgia couldn't keep us from crowning it the brash, arrogant upstart prince of the track-toy Porsches. The company got a lot right with this ultimate Cayman. To begin with, it absolutely looks the part it's supposed to play. Our tester wears searing Racing Yellow paint, that large wing looming over the rear lid is standard, and rolling stock comprises huge 20-inch wheels wrapped in Michelin Pilot Sport Cup 2 rubber. The front fascia is altered for both airflow to the radiators and downforce, standard fare for a hot track-ready version. What's unusual is that instead of complicating the look with tacked-on contrivances (ahem, like the GTS's grille insert-within-an-insert), it's simpler, subtler, and more purposeful. Between that front splitter and the wing, expect about 220 pounds of downforce at the GT4's 183 miles per hour top clip. Ergonomically, even with these fixed-back sport bucket seats, this car is nigh-perfect. Out back, things are more complicated but no less coherent. The lip spoiler that spans the trans-tailight area grows into a little ducktail, literally overshadowed by the larger rear wing. Rear diffusers are a requisite in this class, so one is present and functional. Optimized side intakes just aft of the doors cram more air into the engine, and gain a little embossed "GT4" script. Ergonomically, even with these fixed-back sport bucket seats, this car is nigh-perfect. The slightly smaller steering wheel, perfectly sized for the application, and the smooth, precise shift action make wrangling the major inputs like an extension of your own limbs. If you want to be cynical, go ahead and call the GT4 a parts-bin car. The 3.8-liter flat-six is cribbed from the 911 Carrera S, and the front suspension, steering system, and rear brakes from the 911 GT3. Want carbon-ceramic brakes? Then you'll get GT3 parts on both axles.
