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.

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.

Here are all the EVs with 800V charging available in 2024

As technology advances, electric cars are improving their fast-charging times. That means less time spent waiting at a DC public charger when you’re out on the road. While Level 3 chargers used to provide a maximum of 150 kilowatts of power, 350-kW chargers are become more common, making for super-fast charging Â… if your car is capable of taking advantage of it. So how do automakers improve the charging speed of their EV batteries? Some are turning to higher voltage, specifically 800V charging. What's the difference between 800-volt charging and 400-volt charging? So how does 800V charging improve upon the more common 400V EVs? Put simply, the higher the voltage, the less amperage (current) it requires to charge. In other words, with more voltage, you get more wattage (power, aka charge rate) from the same amperage (current). 800V architecture is also more efficient, with less electrical resistance, so it can use thinner cables and smaller, lighter components while needing less cooling. The tradeoff is that it is more costly, and guess who that cost gets passed on to. While automakers don't break down their pricing to show how much more you're paying for that 800V system, you'll just have to evaluate any potential purchases as a whole, and make your decision based on overall pricing of the vehicle. Thankfully, the 800V EVs on sale now are generally ones we like. Now, 800V charging capability doesn't necessarily mean an EV has 800V vehicle architecture. For instance, the GMC Hummer EV and Chevy Silverado EV operate at 400V, but with their dual battery packs, can switch to 800V when charging by temporarily connecting those packs in series. Currently, there are only a handful of EVs available with 800V charging. But if you are going to find yourself taking longer trips in your EV and using DC fast chargers more often, you might want to consider choosing one with this faster charging capability. With that in mind, these are the EVs available with 800V charging, either on sale now or coming in 2024. 800-volt EVs available in 2024 Audi E-Tron GT Chevrolet Silverado EV Genesis GV60 Genesis Electrified G80 Genesis Electrified GV70 GMC Hummer EV Pickup GMC Hummer EV SUV GMC Sierra EV* Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 Kia EV9 Lotus Eletre* Lotus Emeya* Lucid Air Lucid Gravity* Porsche Macan Electric* Porsche Taycan Ram 1500 REV* Tesla Cybertruck *Coming later in 2024 Green Audi Chevrolet Genesis GMC Hyundai Kia Lotus Porsche Tesla Electric Lucid EV charging
