These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Which sinister Scion FR-S would you buy?

Look beyond the utility. Look beyond the amenities, the infotainment, the hidden storage cubbies, and the 72-way adjustable seats. Yes, even the seats. Outside all the fluff of today's cars, there's a blank canvas waiting for an artist; cars can really come alive with a few tastefully placed modifications. These two Scion FR-S sports cars surely fall into that category, and when they both turned up on eBay, we figured we'd ask the question — which would you rather buy? The track-centric red car or the brutally simple black car ? Internet, you be the judge. The "widebody" look — with its outrageous fender flares and visible rivets—isn't for everyone, but this 2013 Scion FR-S happens to pull it off quite well. According to the listing, the pumped-up fenders, splitter, and additional aero bits are courtesy of legendary widebody purveyor Rocket Bunny. Overall, the racy body mods add a significant twinge of aggression to the once docile FR-S... a notion that's echoed underneath the hood. The heady Scion FR-S leverages an HKS supercharger system and exhaust, paired with a set of Buddy Club racing coilover shocks, Bee-R wheels wrapped in Yokohama ADVAN rubber, and a new engine management system. All in all, this looks to be one fierce track and street monster. RELATED: Check Out This Wild Toyota GT86 Wagon Concept But whereas the red car is a shout, the black car is a growl. Confident, powerful, yet restrained. The black 2013 Scion FR-S sports a sultry Varis Arising 2 body kit with carbon fiber accents lining its front lip and boot lid, as well as a brilliant set of projector headlights and Tom's taillights. The icing on the cake is the set of Work M1R gunmetal grey wheels, which come fitted with Michelin Pilot Super Sport tires. There's no supercharger in play here, but the Scion's 2.0-liter boxer engine does breathe a bit easer thanks new ceramic coated exhaust headers and a high-flow catalytic converter. It can also handle a bit better too, courtesy of sporty Cusco Street Zero 3 coilover shocks. If we're honest, both are quite jaw-dropping in their own unique styles. But which do you prefer?

Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."
