Green Hybrid.. Military Vehicles?

When you typically think of "green" in the auto industry, things like O2 Sensor, oxygen sensors, and hybrid cars like the Toyota Pruis come to mind. I bet the last thing you would think of is the Army's all-terrain Clandestine Extended Range Vehicle (CERV), and yet here it is:

The advantage of going hybrid on a vehicle like this is not only to save gas (getting gas in the field in Afghanistan can cost upwards of $400/gallon... think about that next time you're at the pump); this vehicle can also run in silent (fully electric) mode for up to 8 miles. Combined with it's diesel engine it maintains the ability to go up 60 degree grades and reach a top speed of 80mph.

These capabilities make it extremely versatile: running a diesel engine at 3am isn't the best way to go unnoticed in stealth operations. The silent mode on this vehicle can sneak up on terrorists faster than a Prius when you step into the crosswalk. Plus there is admittedly some novelty to having a giant machine gun mounted to the top of a hybrid vehicle.

This vehicle is part of a larger effort to save money and help the environment without sacrificing power and usability for soldiers in the field. It is being produced by Quantum Fuel Systems Technologies Worldwide (QTWW), the company that makes the Q-Drive, the 400 hp drive train of the Fisker Karma. If you  haven't heard of the Fisker Karma, here's a few details to fill you in: a claimed total range of 300 miles (483 km), the first 50 miles (80 km) of which is on tailpipe-emission free electric-only charge, and it looks absolutely amazing.

There was a time where it was difficult to even get pictures of CERV's, but as the Army has entered one to be on display at the Chicago Auto Show it seems the times are changing. The 25% better fuel economy this hybrid offers not only saves money, but enables military personnel to go longer without filling up. Time will tell if these become a permanent installation in the military, but it certainly seems a step in the right direction to save money and increase utility for today's soldiers.

The Importance of Having a Dash Cam

Have you ever thought about getting a dash camera? Most people are more concerned with whether their Pre-Cat Oxygen Sensors and Post-Cat Oxygen Sensors are functioning properly, and that dash cams are just for police vehicles.

You might want to think again - there are several advantages to having a dash cam, first and foremost having a recorded account of anything you witness while driving. There is a video circulating online currently of a driver with a dash cam who had a car in front of them BACK INTO their vehicle. By law, this would normally be his fault as anything that looks like a rear-end is the fault of the rear driver. However, despite attempts of the front driver to threaten to call the police unless our driver pay him $500 on the spot, because of the dash cam he had evidence for his case.

This is also handy in case you witness a crime while driving, even if it doesn't involve your vehicle. Events like accidents and crimes can happen fast - human memory can prove to be hazy when pressed to recall exact details about a certain moment in time. A dash cam can be very useful in these situations to provide an accurate account of events, and to identify anyone involved.

Serious matters aside, footage from a dash cam can be entertaining. I'm sure you can think of a time when you've seen something while driving that is almost beyond belief, but upon telling the story to your friends it turns into one of those "you had to be there" moments. Showing the footage to friends, and even uploading it to popular video aggregating sites, enables you to share your hilarious moment with potentially thousands of people.

Lastly, footage from a dash cam can be artistic. Want to remember what that road trip was like a few years ago? A neat video compilation of normal hand-held video camera footage mixed with dash cam footage of your trip can provide a very cool experience for you and your loved ones to share.


Whatever you use it for, a dash cam can come in handy in the right moment. For all of it's uses, it seems worth the average $60 investment.

What is a Mass Air Flow Sensor?

A Mass Air Flow Sensor (MAF) is a device that measures thevolume and density of the air entering the engine.  It is the first sensor to read the amount ofair entering the motor. The MAF is made up of an air temperature sensor, anelectronic control unit, and a hot wire.  The main job of this sensor is to convert theamount of air coming into the vehicle into a voltage signal.  Along with the assistance of oxygen sensors,the MAF provides the Engine Control Unit (ECU) with vital information. This datalets the ECU know how much fuel to inject, the timing of ignition, and when toshift a transmission.

There are two main types of mass air flow sensors in automotiveengines, the vane meter and the hot wire. The vane meter is an olderstyle.  It measures the amount of airwith a spring loaded flap attached to a resistor.  The vane meter is not used as often as thehot wire because it restricts airflow, the moving parts wear easier, andfinding a space to mount it is difficult. On the other hand, the hot wire stylehas minimal airflow resistance, it’s smaller, it has no moving parts that wear,and it responds very quickly to changes in air flow.  So, basically the hot wire is a skinnier,smarter version of the vane meter.

If your Mass Air Flow Sensor is malfunctioning your car mayidle erratically, run lean, try to stall, and the throttle could decrease athighway speeds.  If you have a digitalscanner you can make sure that your MAF is to blame by hooking the scanner upto the housing circuit and checking for codes. In some cases the sensor is justdirty and needs to be cleaned, but more commonly the part is broken.  MAFs are rarely repairable and a new one willrun you a couple hundred dollars.

Not Your Normal Tree Huggers’ Prius

Enjoying fresh air is one of those little enjoyments in life.  Taking in a deep breath of oxygen can revitalize the body and mind.  Having your oxygen sensor warning light come on in your vehicle can do exactly the opposite.  Each time the oxygen sensor on my car goes bad I want to sell my car and go live amongst the fresh air in the mountains.  Oh, who am I kidding?  I would have to get a vehicle. Maybe I would stick with the environment friendly theme and go with a Prius.  Actually, forget being friendly to mother earth. I would buy the new Prius GT300.

The Prius as a race car? No way! Ok, maybe a race to see who can transport the most granola on the least amount of gas, but not an actual race.  It took me a while to believe it, but it looks like Toyota is going to make a Prius that can compete in the Super GT Series.  That means they’re going to produce a Prius which has at least 300 horsepower.  Considering a stock Prius comes with an 80 horsepower electric motor and a 98 horsepower gas engine, the boys at Toyota have some work to do.

Now, is Toyota choosing the Prius as their Super GT car because they think it gives them the best chance to win, or are they trying to muscle up its image?  This question is up for debate.  I know that my perception will be different when I see one flying around corners at 200 mph, instead of crawling through a Whole Foods’ parking lot.

There’s buzz that Toyota isn’t the only one entering a hybrid into the Super GT race series.  Honda is reportedly getting the CR-Z ready to race with the big boys too.  With all this hybrid racing going on, who is going to have time to save the whales?
