When the first mainstream electric cars, the Chevrolet Volt and Nissan Leaf, hit the market, they were advertised as being easy on the pocketbook and good for the environment. Because of their size and weight, may consumers had concerns that safety may have been compromised in order to meet the promised fuel efficiency. Recent crash tests done by the Insurance Institute for Highway Safety (IIHS) have shown that this just isn’t true. In fact, both cars have received “Top Safety Ratings” receiving the highest possible ratings for front, side, rear, and rollover crash protection. According to Joe Nolan, the IIHS chief administrative officer, Eco-minded drivers keen on switching to an electric vehicle should not think twice about buying a Leaf or Volt for highway driving. General Motors and Nissan have shown that safety doesn’t have to be sacrificed for fuel economy.

With millions of recalls issued every year, it is not surprising that an estimated 25% are never fixed. Even though new car dealerships are forbidden from selling vehicles with open recalls, there’s no similar requirements for used car dealerships. According to Clarence Dithlow, the executive director for the Center for Auto Safety in Washington, “Every safety defect is serious and should be fixed, and better regulation is needed to ensure that they are.”

National Automobile Dealers Association (NADE) opposes any legal mandate that would prohibit a dealer from selling a vehicle with open recalls, because forcing used car dealerships will impose major costs and burdens on used car commerce. They say that it is the responsibilities of owners of pre-owned vehicles to investigate if a recall has been issued for their vehicle.

The modern car interface can do everything from making a dinner reservation to reading your text messages. In order to do this, an array of knobs and buttons are needed on the dashboard making the use of the system much more confusing. Sam Grobart, the Times’ personal technology editor, shows us three different interface systems that are trying to solve this problem. He test drives the Acura ZDX, Ford Focus, and the Audi A8 and finds that making our lives easier can often be frustrating.

With rising fuel costs, many consumers are turning to diesel vehicles for their better fuel economy. Most people who operate and maintain diesel engines are familiar with a black material seen in fuel filters or at the bottom of the tank, but many don’t realize that it is a growing “algae”. This organism inside the tank will lead to poor combustion, carbon buildup, and could end up costing the owner of the vehicle large amounts of money.

The algae is the result old fuel, and while the problem is often found in boat engines, automobiles are not immune. So what can be done to prevent the problem? There are additives you can use, but if it is not caught soon enough, it can still end up being costly to the consumer. Your best line of defense is being educated about the problem, and keeping up with regular maintenance.
