Investigators blame speed in fatal Paul Walker crash

When the tragic news first came in that actor Paul Walker had been killed in a car crash, family, friends and fans were left searching for answers. They now have at least one key question answered, with the Los Angeles County Sheriff's Department blaming "unsafe speed" for the fatal accident.
According to a statement released by the LACSD, "Investigators determined the cause of the fatal solo-vehicle collision was unsafe speed for the roadway conditions". The investigation into the November, 2013 crash determined that Walker's 2005 Porsche Carrera GT had been driven by his business partner and racer, Roger Rodas, at speeds between 80 and 93 miles per hour - less than the 100+ mph initially suspected, but still far too fast for the road on which they were traveling, which carried a posted limit of 45 mph.
In the investigation into the death of the Fast & Furious star and his friend, some people were quick to finger the Porsche in which they were riding as the culprit. The Carrera GT does, after all, have the reputation of being a notoriously difficult car to control. But after an exhaustive investigation, law enforcement officials in California have vindicated the car and dismissed any mechanical fault as the cause of the accident.

Mercedes S63 AMG Coupe vs Porsche Panamera Turbo S in unusual lux showdown

We'll admit it, we're really looking forward to more time with the Mercedes-Benz S-Class Coupe. Compared to other high-dollar luxury coupes - we're looking at you Bentley Continental GT - it's more stylish, easily more affordable, and since it's a Mercedes, lacks the sense of fragility that comes with a more exotic name plate.
Auto Express has taken a whack at reviewing the new two-door S-Class, and for some reason, the British mag is comparing it with a Porsche Panamera. Now, while comparing the looks of an S-Class Coupe and a Panamera is a bit like holding a beauty contest between Kate Upton and Medusa, this isn't as bizarre a pair as you might think, particularly when you opt for the high-dollar S63 AMG Coupe and the Panamera Turbo S.
The two offer similar power outputs from their force-induced V8s - 577 horsepower in the Benz and 570 horsepower in the Porsche - and are even similar in terms of interior and exterior dimensions. The S-Class actually has an extra inch between the axles and is 1.2 inches longer overall (it's also about 300 pounds heavier). In the cabin, the S-Class also has a tiny bit more rear legroom, with 33.4 inches to the Panamera's 33.3.

Autocar pits Porsche 911 Turbo S against Formula 4 racer

There is a long-running argument among performance car fans: power vs. weight. In one corner you get cars generally with small engines making modest numbers but able to corner like they are telepathic, and in the other there are big thumping mills that are rocketships in a straight line but lumber in the turns. Autocar takes an interesting look this continuum in a recent video pitting a 552-hp Porsche 911 Turbo S against a 185-hp Formula 4 racecar. It hopes to find whether the Porsche's huge power advantage is enough to defeat the better grip and aero offered by the nimble racer.
There's no doubt that the Porsche is an utterly fantastic road car. The 911 Turbo looks mean with all of those intakes to suck in cool air, and it backs up the posture with huge amounts of grip available thanks to its all-wheel drive-system. However, at 3,538 pounds, it's a bit of a porker compared to the 1,135-pound Formula 4 car. The open-wheel car boasts just a 2.0-liter naturally aspirated four-cylinder from Ford and a six-speed sequential-manual gearbox, but it has loads of downforce to make up for it.
It shouldn't be a surprise that the formula car wins in the corners. After all, that's what it's made for. So do you think the massive horsepower superiority of the Porsche is enough to even the playing field? Scroll down to watch the video and find out, and even if you're not curious of the winner the 911 does some mean powerslides.
