Alloy wheels are excellent benefits or serious drawbacks?

Many people prefer alloy disks that look elegant and attractive. However, when buying such products, should pay attention to certain benefits and disadvantages of alloy disks, which are submitted in this article. For many buyers represented criteria could be decisive in choosing drives.

Expressive title “alloy wheels” includes two large groups: iron-shod, stamped in an industrial conditions and alloy wheels which are manufactured by cast in the form. Accordingly to the name, lightweight aluminum or magnesium are the basis of technology. Such decisions increasingly captured the market, and it happens due to the advantages that are inherent only in this type of drive.

Of course, the main advantage is light weight in comparison with steel. What does it mean? At first, mass of the drive to the wheel is reduced and thus its original position after passing the pits and potholes is faster returned. At second, the cumulative reduction in the weight of all wheels increases dynamic of the car, when the processes of acceleration and deceleration are performed with greater efficiency. The stability of the car significantly increases and a careful balancing of alloy wheels will help neutralize the effect of vibration on the transport suspension. At third, it is certainly a great visual attraction.

Alloy wheels in depend of drab steel can boast a wide model range, because the process allows to manufacture drive, commencing from classic and elegant shape to the most incredible. Any car will be look elegant with neat, shining in the sun, light alloy wheels.

However, among attraction advantages and there are disadvantages. At first, such drives, maintaining a constant static load, are very susceptible to sudden hit, which lead to chipping and cracking. In other words, where the steel wheels is bending and wrinkling, alloy wheels easy to break. At the same time alloy wheels damp hit, absorbing some of the damage, but forged by virtue of its rigidity transfer impact energy to the suspension, leading to its deterioration and failure. At second, the cracks may be unobvious that early or later lead to a sad result. Drive with a flaw will break at high speed. Well, price is the last negative aspect. These drives are several times more expensive than steel drives.

A Short Notice on What to Expect from the New Diesel Cars

It looks like the US and Canada are always left behind all other countries when it comes to diesel engine automobiles. Of course, you may find something if you try hard but it is practically nothing compared to Europe. It is interesting to know that more than a half (52%) of all sold vehicles in Europe was based on diesel-powered engine. At least, this is what the Automotive Data Newsletter says.

There are many benefits that are offered by diesel cars. There is enough torque available to increase the usability of those mini power manufacturers – the diesel engines – hidden inside our cars. Diesel engines are also smaller than their gasoline ‘brothers’ but preserve the same high functionality. Hybrids are not characterized by towing. Meanwhile, diesel car engines offer the same rate of efficiency and economy that is quite close to the levels offered by a hybrid. You won’t have to worry about usual ‘new technology’ concerns. You won’t need to tolerate the expenses of storage or passenger space to create some battery pack storage – it is simply not necessary.

Considering these advantages, along with the manufacturers’ constant attempts to improve the traditional standards of fuel economy, many diesel cars are going to enter the American and Canadian market very soon. If you are going to replace your regular car with the new diesel vehicle, there are several reasonable option for you to take into account.

The first one is Mercedes-Benz GLK250 BlueTEC that will appear in the public market in 2013. This is a powerful alternative to some crossover utility cars – it had four cylinders. It has less horsepower (by 112) if you compare it to the most popular gasoline version GLK350 but you will definitely like the better torque (96 lb-ft). The official figures of EPA have not been yet published but the anticipated average interval is from 36 to 38 mpg in various driving conditions. Although European statistics is traditionally a lot higher than the numbers represented in EPA, a level of 30 mpg will still be very impressive.

The other option to take is Chevrolet Cruze Diesel. It is an eco-friendly vehicle with a normal manual transmission of the sixth speed. If you are looking for something really money-saving, Cruze Eco is a perfect fit. It is very efficient in managing fuel. The official statistics for Chevrolet Cruzo Diesel have not yet spread but the rumor is that the highway rate exceeds 50 mpg. There is not much information available about this model but the sales level in Europe may demonstrate that this option is quite promising. The sales of Diesel Cruzo in Europe are 33 thousand cars in 2011.

Cadillac ATS Diesel is also a must, especially if you were interested in BMW 3 Series before. It was a complete surprise – a pleasant one – when the Detroit Auto Show this year revealed that the diesel version of Cadillac ATS will enter the American market. However, you need to be patient if you feel real interest for Cadillac ATS with a diesel engine. There is no release date available for the public yet. It should be some time during the product cycle period.

Jeep Grand Cherokee with a diesel engine was frequently presented at the best auto shows of the world; however, the manufacturers were careful about the declared markets where this model would be available. Nevertheless, Chrysler announced that more employers were being hired for the extra help in Jeep Grand Cherokee diesel version for the US market. The European figures are 28.4 mpg which should be more in EPA testing. The older version of this jeep in America earned a score of 22 mpg.

BMW i8 is ready to be the top-class speed leader of the future

BMW i which is one of the brand branches within BMW is intended to overcome the expectations of the car drivers in terms of high speed. One of the best examples of this assessment is i8 Spyder. It has the same coupe i8 that was launched a year ago with the city car i3. It is a successor of the previous super models but it seems to be much closer to the point of public sale availability. It is quite similar to i8 coupe in many ways: for instance, it is also a plug-in hybrid with through-the-road features. Its electric up front powering goes up to 96 kW (which is equivalent to 131 horsepower).The engine inside is mid-mounted, gas and turbo-charged. It has three cylinders (the suggested displacement is also the same as in the coupe – 1,5 liters) and is able to produce 223 hp to power the rear. The batteries which are lithium-ion-based are placed inside the center tunnel in between two power sources that work together to create a general system output of 405 torque lb-ft and 354 hp. Being tied to electricity only, the i8 Spyder is able to ride for about 19 miles until the gas engine switches on for the battery recharging. The manufacturers claim that this system is perfect for 94 miles-per-gallon mode on the Imperial cycle that converts to 78 miles-per-gallon mode on the EPA cycle.

One of the greatest advantages of i8 Spyder is its transformability: it can be driven with the front wheel, rear wheel or all wheel mode according to your demands on performance. For example, if you are willing to develop maximum efficiency, the front-wheel-drive will be great. When it comes to maximum performance that you are focused on, try rear-wheel-drive. If it is the all-weather mode you want to choose, switch to the all-wheel-driven option. The weight distribution of 50:50 is also taken after the coupe BMW version, and BMW manufacturers promise that the excessive weight from the hybrid drivetrain has been completely taken off. This became possible due to the extended usage of lightweight metals and materials like aluminum and carbon fiber. The performance of the i8 Spyder won’t leave anybody indifferent too due to 0-62 mph happening just in 5 seconds and the achieved top speed level of 155 mph.

Howsoever, there are some enhancements inside i8 Spyder that make it quite different from the coupe version. The overall length of this car is a little shorter as well as the wheelbase. The doors inside are windowless and swiveling upwards. It is interesting that the designers also included a couple of electric-based scooters that stay below the rear glass panel. Apart from several other accommodations intended to make the open air design more convenient (it can be turned into closed design again with a unique roof that folds in two sections), the remaining elements of i8 Spyder are the same as in the coupe. The interior design is similar too but it has a warmer color palette chosen.

Be sure you are tuned up to the latest news from BMW, and check on this website to see more personal impressions on test drives and everyday rides for BMW i8 Spyder. Although BMW manufacturers still remain silent on the first appearance of i8 Spyder on the closest New York Automobile Show, you will be the first to know when the demonstration time is set.

How to Shift Gears on a Manual Transmission

Shifting gears on a manual transmission is a delicate balance of knowing when to shift and how. If you do it wrong, it will be glowingly obvious. It is very rare that a car will die during a gear shift, but it will not be a pleasant ride. But once you learn to do it properly, you will be able to shift gears as smoothly as an automatic.

Instructions

1. The best way to learn when to shift is to either ride around with someone who already knows how to drive a manual transmission and watch when they shift. Or you can drive your automatic and feel when the transmission shifts. In either case, you are looking for the sound and feel of the engine at the shift points. Remember this.

2. There are several styles or speeds of manual transmission around, any where from 3 to 6; although the 5 speed is the most popular. The shift pattern will vary widely. But, it should be engraved on the gear shift lever.

3. Instrumentation is going to vary widely from car to car, but most cars with manual transmissions have a tachometer, this is very useful in knowing when to shift. If you don’t have one, your car may have an orange light that tells you when to shift. If you don’t have one of those, then you will have to rely on speed and the feel of the engine.

4. You will shift when the tachometer is at 2,000 RPMs – if you have a light, it will come on at this time. That is true for what ever gear you are going into. If you don’t have a tachometer, then you will shift about every 10 MPH. That is at 20 MPH you shift into 2nd, at 30 MPH you shift into 3rd, at 40 MPH you shift into 4th and at 50 MPH you shift into 5th. Thus, if you are going 35 MPH you should be in 3rd gear.

5. If you are already proficient at getting the car going and stopping in first gear, you are experienced in balancing the gas and clutch, if only a little. You will need to use this when changing gears. When you reach the proper RPMs (or speed) let your foot off the gas, press in the clutch and, using your right hand, shift into the next gear. Let the clutch out carefully and continue to accelerate. If you let the clutch out too fast, the car will lurch forward. If you don’t let it out before you accelerate the engine will whir. If this happens let your foot off the gas, and then let the clutch out. If you let the clutch out too slow, the car will chatter and jump. Either way it’s not a fun ride. The good news is; this will prompt you to work on the proper timing of clutch and gas.

6. Down shift to the next lower gear, whenever your RPMs drop below 1500. Down shifting is the same as up shifting, press in the clutch, and let your foot off the gas. Using your right hand, shift to the next lower gear and let the clutch out. You will feel a decrease in engine RPMs and speed.
