Electric Vehicles

There has recently been a rise in electric vehicle sales and automakers are continuously working on technology to make their battery-powered vehicles better. There are many benefits and some downsides to owning an electric vehicle. Some of which may be a deal-breaker depending on your situation. If you drive long distances often the choice of electric vehicles today may not be good for you. However if you drive a short distance daily an electric vehicle may be perfect for you. In order to decide what is right for you, you should weigh the benefits and the disadvantages.

Electric vehicles are much more energy efficient than gasoline-powered vehicles. EV’s (electric vehicles) are able to convert about 60% of their power to their wheels. Whereas gasoline vehicles are only able to convert about 20% of their power to their wheels. This not only means you have much more power altogether it also means that you have much more power much quicker than in a gas powered vehicle.

Electric motors provide a quiet and smooth operation and a stronger acceleration. They also require less maintenance than internal combustion engines. The battery, motor, and other electronics require little to no regular maintenance, they have fewer fluids to change, and they use a brake system called regenerative braking which significantly reduces brake wear. The process of regenerative braking uses the otherwise lost energy from braking and sends it back to the electric motor for use. This technique is much more efficient than in a gas powered vehicle where the energy used to brake is lost as heat. There are fewer moving parts and the batteries are made to last the life of the vehicle and many automakers offer warranties up to 100,000 miles. The government also offers incentives to purchase an electric vehicle that could be as high as $7500.

One downside to EV’s is that the driving range is typically very limited. Many models can only go up to 120 miles on a charge where others can actually go 300 miles. Not only that but just because the batteries are supposed to last the lifetime of the vehicle doesn’t mean they always do. Having to replace the battery packs on an EV outside of a warranty is an extremely expensive job. On top of that a full recharge can take up to eight hours. Finding a place to do this is also sometimes difficult and may leave you stranded.

California has recently announced they will be investing money into building roads that harvest energy which could possibly be used to fuel electric vehicles. Tesla has also announced a project they are working on which will allow the batteries in these vehicles to be recycled – a problem that we have faced ever since battery-powered vehicles came into production. There is no way to safely recycle the used batteries yet. The technology in these cars is relatively new and as the technology progresses we will most likely see a large increase in electric vehicle volume.

Tips to Save Gas Mileage

Gas prices are something most of us can’t control. The one thing we can control is how much we use of it. If you can’t cut your commute down there are driving techniques that will save you gas. These are some things you can do that will allow you to get the most fuel efficiency from your vehicle.

 
Aggressive driving is an obvious culprit of lowered mpg. But did you know that it can lower those gallons by up to 30 percent at highway speeds and up to 40 percent in stop-and-go traffic? This type of driving can mean anything from speeding, rapid acceleration or hard braking. A fairly obvious technique which could help with saving gas would be to keep at or below the speed limit. Once you hit 50 mph your gas mileage starts rapidly decreasing. Cruise control is a good tool to use. No matter how fast you are going it will maintain your speed and limit the use of unnecessary acceleration. Overall be a little more gentle with the gas and brake pedals.

 
Don’t forget that a vehicle with low tire pressure requires more fuel to move it forward. Check your tire pressure monthly and refill tires to the recommended pressure that is on the tire itself. Likewise a wheel alignment that is not straight can cause you to drag the tires which will certainly decrease mpg. Your alignment should be checked yearly and reset if needed. Not only will keeping your vehicle aligned and tires aired up save you money on gas it will also extend the life of your tires which also saves you money.

 
Also avoid hauling cargo on your roof when unnecessary. Roof pods and cargo nets are great for traveling but not for daily driving. Driving at freeway speeds can reduce your gas mileage up to 25 percent with a large cargo carrier on the roof. Bikes and racks on the rear of your vehicle can create a drag of up to 5 percent worth of fuel. Likewise try not to carry any extra weight within the car either. Keep it clean of trash or unnecessary items.

 
You should also consider the amount you idle your car. Excessive idling drinks your fuel and can use up to 1/2 gallon of gasoline per hour. Try to turn your car off if you know you will be idling for more than a couple of minutes.

 
Overall don’t forget to consider outside sources such as weather when thinking about your gas mileage. Some things are just out of your control. However do your best to make the most out of what you can control and bump up those mpg’s.

Vehicle-to-Vehicle Communications

Autonomous cars are still part of the future but cars that talk to each other are a reality now. The United States Department of Transportation has proposed a rule that would require all auto manufacturers to equip light-duty cars and trucks with vehicle-to-vehicle communications or V2V.

 
This rule would go into effect in the year 2019 and there would then be a deadline of 2023 for compliance. DOT believes V2V technology has the potential to prevent hundreds of thousands of crashes each year. The technology allows vehicles to communicate with each other sharing weather conditions and any traffic concerns. This proposed rule would include other safety software as well such as automatic emergency braking.

 
Cadillac has announced the addition of V2V equipment to their vehicles. The feature will now be standard in cars in the US and Canada. These devices will be able to communicate with other vehicles up to 980 feet away. This system is proposed to be much more effective once all new cars have it. V2V has been said to contain firewalls to keep it protected from interference and also prevent any sharing of personal information so you don’t have to worry about any of that.

 
As high-tech as this technology sounds it has been estimated that it will only add about $200 to $300 to the price of the car. However, the safety benefits that V2V will produce will not be achieved until a mass amount of cars with this system are on the road. Cars can’t talk to each other if only a few can speak and listen. This is an exciting step forward as technology continues to grow and expand.

Is Your Car Summer Ready – A/C?

The weather is changing quickly here in Las Vegas and the temperatures are rising. As long as the temperature stays hot outside and cool inside there shouldn’t be a problem. But what do you do if you get in your car on that first hot day of the year flip on the air conditioning and find out what’s blowing through the vents is just as hot as the air outside? No matter how long you let the A/C blow it doesn’t get any cooler. Perhaps that isn’t your problem though and the air blowing is cool but not cool enough. Whatever the situation may be if your A/C is not blowing cold you have a problem.

The air conditioner in our vehicles is an enclosed system that contains a gas called freon. The gas is circulated throughout the system by the compressor. The expansion valve or orifice tube changes the freon gas to a liquid which makes it get cold. While the cold freon is circulated through the evaporator core, the blower blows air across the core to send cold air into the cabin of the vehicle. This gas is highly pressurized and any leak in the system will cause noticeable side effects. Any higher than usual temperatures coming from the A/C should be looked at right away before the problem gets any worse.

The most expensive A/C fix would be replacing the compressor. If the compressor becomes defective the freon has no way of cooling the air. Sometimes the compressor can leak and when that happens, there is no bandage, it’s a new compressor or no A/C. Most commonly though the leak is usually caused by old hoses. At that point, the hose is replaced, a recharge done, and your A/C will be back to normal.

As to ensure you don’t get stuck in the middle of the summer without A/C it is a good idea to have the system checked in the spring time. Finding a problem before it evolves can often save you from many more expensive repairs. If you have any doubts that your A/C is performing at its peak then have it looked at by a professional. Bob’s Autodynamics has serviced air conditioning systems for 31 years and is ready for another hot Las Vegas summer.

Hot Summer Days Make For More Expensive Gas

As we move into spring and the hotter months here in Vegas, we start to see an increase in our gas prices. This doesn’t just happen here though, it happens all across the country. It’s a common fallacy that summer gas is more expensive due to higher demand, like more road trips and more gas used to fuel the A/C on those hot days. While demand definitely plays a factor in gas prices, the summer hike-up is due to EPA Regulations.

Between June 1st and September 15th the Environmental Protection Agency, or EPA, requires oil companies to sell gas that is less likely to evaporate. This is due to the fact that higher temperatures cause more evaporation and smog, which leads to less gasoline in the fuel tank. In cooler months, evaporation is less of a concern and regulations by the EPA are less strict.

In the winter, oil companies are able to use a chemical called Butane. It is the same chemical you find in Bic Lighters. It is cheap to use but evaporates easily which is ideal during the cold. On the downside, Butane contains less energy than other petroleum products which means you get less bang for your buck. This is the reason you probably experience worse fuel mileage in the colder months.

Throughout the entire year, your fuel costs will be relatively the same. Between higher prices in the summer, and having to buy more in the winter, you shouldn’t sweat the extra couple of dollars on the fill-up since it will get you a couple of extra miles.

Car Brands: What Are You Actually Driving?

Many of the vehicles we drive today come from parent companies of the brand that is actually on our car. Here is a break-down of who-owns-who currently, keep in mind, this is an ever-changing list.

  • BMW, which stands for Bayerische Motoren Werke, is part of a shareholder corporation which also owns Mini and Rolls-Royce. BMW also takes #14 on Forbes list of most valuable brands.
  • Fiat, or, Fabbrica Italiana Automobili Torino, is an Italian brand which owns Alfa Romeo, Ferrari, Maserati, and all the Chrysler brands including Dodge, Jeep, Ram, and SRT.
  • Ford owns Lincoln and a small stake in Mazda. The company used to own Jaguar and Land Rover but sold to the Indian company Tata Motors in 2008.
  • GM owns Buick, Cadillac, Chevrolet, and GMC. GM is the brand from a few years ago that tried to argue any modifications you do to a vehicle are illegal and break the licensing agreement you signed at purchase. However, this argument is a discussion for another day.
  • Honda owns Acura. These brands are somewhat young compared to some of the other brands – which is interesting due to the fact that Honda is known for its affordability and its reliability, something that takes many brands a long time to achieve.
  • Hyundai partially owns Kia. The first vehicle ever produced by Hyundai was a project with Ford and was called the Cortina.
  • Mazda mostly owns itself, with that small stake from Ford as well.
  • Mercedes is owned by a company called Dalmer AG, who also owns Smart and did own Maybach before the brand was killed off.
  • Mitsubishi is independently owned under the Mitsubishi group umbrella in Japan.
  • Nissan owns Infiniti and the newly revived Datsun which has been reintroduced in Sri Lanka where it was originally first sold. They are also partnered with Renault.
  • Subaru is partly owned by Toyota, which explains the recent partnership to build the European-known Toyota GT86 or the American versions, the Scion FRS and Subaru BRZ.
  • Tesla is partly owned by Toyota and has a partnership with Mercedes.
  • Toyota owns Lexus and the recently discontinued Scion, which Toyota will more than likely absorb and re-brand as their own.
  • Volkswagen owns Audi, Bentley, Bugatti, Lamborghini, and Porsche. VW also owns the worlds most expensive car – the Lamborghini Veneno that prices at just around $4 Million.
  • Volvo is owned by a company named Geely, and interesting enough, Volvo is the one who invented the seat belt almost 50 years ago.

It makes sense as to why so many different brands have such similar vehicles. Many, like Nissan and Infiniti, make essentially the same car, but one in a standard class and one in a luxury class. We will most likely continue to see car makers buy and sell other brands and continue to revolutionize the vehicles we know today.

Is Your Car Full of Hot Air ?

Air…….it is everywhere. Used for just about everything. Most importantly breathing. Like all living creatures the engines in our vehicles need air to breathe. Human and mechanical filtering systems serve the same purpose they keep dirt, dust and contaminates out. It can take as much as 10,000 gallons of air for every gallon of fuel an engine uses to operate. Humans have “natural” filters. The engines in our vehicles use artificial filters. A vehicles air filter working properly can improve power, economy and performance up to 10 percent. That is why checking and replacing a dirty air filter is important. A good basic rule would be to replace an air filter every 15,000 to 20,000 miles during average conditions. Average conditions means clean roads and moderate temperatures. In Las Vegas the roads along with dusty conditions require more frequent air filter replacement. The air filter should be checked with every oil change. Happy Motoring and Be Safe.

Everything Needs a Battery

Used to be the only time you really needed batteries was at Christmas time. Now they are needed for just about everything especially electronic devices. Even our vehicles have always needed batteries and now some vehicles run on batteries only. Just like our various gadgets car batteries need attention in order to keep vehicles functioning properly. Car batteries store the electrical energy required to start and run our vehicles. Car batteries are not going to stop functioning in your driveway. They will pick the most inconvenient place possible. Car batteries have a lifespan of 2 to 3 years. Depending on climate conditions batteries 3 years old or older will experience failure. While a battery tends to last longer in a cold climate extreme cold and heat will also deteriorate a batteries functioning ability. Routine maintenance can help your battery function properly. Regular checking of cables for cracking or fraying, battery connection for corrosion and in some cases the water level inside. Batteries should be tested every three to six months. Some warning signs are; lights will dim when air conditioning or heat is on or corrosion on battery cables. Has the battery needed a jump start or external charge? Is the battery past the warranty date ? These are all indicators that you may need to get a new battery. So as we enjoy our battery powered electronic devices we should also make sure our vehicle battery is maintained in order for it to function at its peak. Happy motoring and be safe.

Women Taking Control of Their Car Services and Repairs

When I opened Bob’s Autodynamics way back in 1986 almost everyone we dealt with was a man. Back in the day men were in charge of taking care of the family car needs. They would make the decisions of what should be done or not done. In some cases I’m sure the woman may be helping with those decisions but we still always seemed to be dealing with the man of the house. Fast forward to today and boy have times changed. In todays world I would say that women represent over 50% of the customers we deal with. I must say sometimes change is good. It’s a pleasure to help women with their car needs. Women tend to be better listeners when we are explaining or educating them on anything they may not understand about their car and why they need the services or repairs suggested. Sorry guys I think with some men their egos get in the way and they don’t want to admit what little they know about todays cars. Just to be fair todays cars are very complex compared to the old days before everything (not just cars) came equipped with a some type of computer. I’m glad to see that todays women take on their car needs with confidence. They know that taking care of the second biggest or the biggest investment in their lives will pay off and pay off big. We a Bob’s Autodynamics take great pride in being able to help anyone understand and educate them on how their car works or why is it broken. If you have any questions don’t be afraid to ask just stop by or give us a call and we will be glad to help you.

Relationships With Your Mechanic

Do you go to the same doctor for checkups? Do you go to same dentist for cleaning or checkups? Most people do because they like to have the same people taking care of them and having their medical history. It’s all about building relationships with the people you trust to take care of you. If you own a home your car will be the second biggest investment in your life. If you don’t own a home your car will be the biggest investment in your life. Just like we need to take care of our teeth with maintenance by flossing, brushing and regular checkups you should be maintaining your car. Regular checkups and maintenance is going to keep your car healthy. It’s to your advantage to find a good repair shop and stick with them. Just like your doctor a good shop will keep all the maintenance records for your car. They will help you stay on top of everything your car needs based on your personal driving habits. From how often you should change your oil and filter to letting you know when it’s time for other maintenance like cooling system flushes, transmission services and cabin filter replacement. They will know if you are the type of person that uses their brakes with a heavy foot or the type that is light on their brakes. Guess what type of person does more brake jobs? At Bob’s Autodynamics we build relationships with our clients. After 28 years in business we have 3 generations of families coming to our shop. It’s really fun watching our clients children grow up and start driving their parents car or maybe if they are lucky their own car. We enjoy helping those young drivers learn how to take care of their car just like their parents and grandparents. Yes it’s all about relationships.
