Ferrari 458 Italia New WALLPAPER AND REVIEW

Ferrari 458 Italia New WALLPAPER AND REVIEW-google2

Italian manufacture launched Ferrari 458 Italia New WALLPAPER AND REVIEW 458 Italia, it is the two-seater mid-rear engined berlinetta,this Ferrar is the latest addition to the Prancing Horse's history. Ferrari 458 Italia is expected to be unveiled at the upcoming 2009 Frankfurt Auto Show. The result of the Ferrari engineers’ endeavours can be summed up in to two simple statistics which together perfectly encapsulate the Ferrari 458 Italia’s exceptional performance: 0-100 km/h acceleration in under 3.4 seconds and a maximum speed in excess of 325 km/h.

New Performance Lamborghini Reventon

Based on the Murcielago concept, Lamborghini created Reventon at Saint’Agatha, Italy wich heads straight from the spotlights of Frankfurt motor show halls. Moreover, the clientele is limited(20 owners by October 2008) and the price varies around $1.365. Its engine is powered with 650hp at 8000rpm, right coveted 100-hp/liter mark and 10hp more than the LP640-which dates back from Lamborghini pre-Miura days, even if claims the same speed and acceleration numbers as the Lp640.

The carbon-fiber masterpiece was inspired by the F-22 Raptor Jet,as the brand and design manager talks,Manfred Fitzgerald talks about of every team’s member involvement and creativity in order to soak up dynamic views of the jet design. The rear lights,which are carbon fiber with LeD inserts,or the carbon fiber struts across the top of the engine bay,with a transparent cover,will definetly keep people talking.

Though the Reventon ticks every box in the Murcielago’s options list ,like carbon ceramic brakes,forged-aluminium wheels with fiber inlays,no panels are shared with the LP640-only the side mirrors have been carried over from it. Fitzgerald claims that the Reventon is designed to go straight from sketches to CAD production,and not only a piece of design.

The quarter-scale model,allowed them to reduce production time tremendously,because it has been all virtual,and the higher cornering speeds than the LP640 are due to the aeronautics inspiration-arrowhead nose and visible carbon-fiber splitter that provided the car with more front downforce.

Equipped with a digital dash,it allows the driver to enjoy a digitized version of the traditional round,and while the bodywork will capture the attention of the overwealming majority,it is the instrument cluster(all aluminum) that lends the car more technical credibility9.

The rest of the interior is stylish,equipped with greenish Alcantara seats which follow the design of the sharp arrow idea,or nappa leather around the cabin,similar to that in the Gallardo Superleggera.

It is question whether the Reventon worths its million dollar price due to its comparison to the LP640,though its price is justified by pointing out the months of research and its different body and interior design,with the lefthand drive.The 20 Reventons have already been sold and are on the sales list among Bugatti Veyron,The Mercedes Benz CLK and Ferrari Fxx.

Fiat Uno spec and review

One of the abundant affidavit of pride for the Fiat Style Center for Latin America is the absolute action for conception of the new Fiat Uno, but this would beggarly little if the end artefact was not special. And the new Fiat Uno is special.

From the alpha of the conception process, designers formed ancillary by ancillary with a analysis studio, allurement questions, presenting proposals and accepting feedback.

The rationale: by alert to the client, it would be accessible to awning and clarify his/her suggestions in adjustment to actualize actually the car of his/her dreams. What the designers begin out was that the aboriginal Fiat Uno, the icon, should be the starting point for an actually new car. The Fiat Style Center started drafting the new car, and the analysis bent if it was actually what the applicant wanted. The answers acicular out the aisle to be followed.

The result: an actually aboriginal concept, humorously called "Round Square," which guided the absolute development of the new car.

And what is actually a annular square? Going from the figure Uno and its aboveboard shapes, the designers created the "New Square": pop and modern, the evolution. To accord it a shape, they acclimated bounds from Automated Design (industrial drawing) - instead of the acceptable attempt of Automotive Design, with its curvier, active curve - to actualize the annular curve of the new model.

Adopting the aboveboard as a reference, a car with geometrical, counterbalanced shapes was conceived. The squares with curves booty aback to Fiat Uno, but, at the aforementioned time, represent a abreast abstraction and a trend from now on. Past, present and approaching agglutinate with aggressiveness and accompany the new.

High Performance, Extreme Quality Are The Norm At BMW

Once portrayed as a small town, Woodland Hill is nothing like that. It is a busy suburban area of Los Angeles. Sitting northeast of Calabasas and Tarzana, it is an exclusive community for the wealthy. It is a place where quality and luxury definitely are important. Manicured lawns, majestic homes, and luxury cars are the staple of this small area. Of course there is no greater luxury than a BMW. At Woodland Hills BMW, cars, SUVs, and motorcycles are the norm.

Because of the luxuriousness and quality of this car, it fits in well in a city like Woodland Hills. BMW stands for Bavarian Motor Works. They are an automobile maker that is based in Germany. They have been producing luxury vehicles since 1913. BMW is also a world renowned manufacturer of motorcycles. They produce these under two brands; BMW Motorrad and Husqvarna.

For the motorsports enthusiast, BMW makes cars and motorcycles just for you. The company has been a proud sponsor of motorsports and car racing since it began building motorcycles. It is the proud sponsor of two races; the Formula BMW and the Kumho BMW Championship. Its world class and super fast motorcycles have won the Superbike World Championship and the Dakar Rally. Besides motorcycle racing, the BMW brand has been found in car races all over the world. In fact, BMW cars have won 20 Formula One Grand Prix races. BMW cars are also found in Sports Car races and Touring car races and have been successful there as well.

There are many reasons people give for wanting a BMW. Besides being a great looking car, it is the best manufactured vehicle in the industry. This car can be driven wherever your heart desires. That is what is unique about its manufacturing and design. From driving on the highways of Los Angeles to the mountainous curves on the valley, this car is made to withstand any kind of driving you can think of.

Every year, BMW manufactures well over two million cars, SUVs, and motorcycles. There may not be a single person in this world who would not like to own a BMW at least once in their lifetime. Many people dream of owning this car. But it is not a car for the average person, especially since there is nothing average about a BMW. It is a special car to be driven by a unique individual.

This car is built to last forever. There are hundreds of car makers but BMW stands alone when it comes to ingenuity. Their repertoire includes all ranges of vehicles from convertibles to station wagons, executive sedans to sport utility vehicles. However, their most popular car is the M series. This car defined an entirely new market for the company. This is an actual race ready car with an award wining V-8 engine that you will not find in standard BMWs. No matter what kind of BMW you choose, you are sure to get an amazing vehicle that will suit all of your needs.

Even though they are considered to be the manufactures of the best car in the industry, BMW is a company that cares about the environment. They have been praised for their environmental responsibility and are members of the United States EPA (Environment Protection Agency). They are working extremely hard to reduce their impact on the environment today. They have been manufacturing vehicles that emit less pollution and are in the process of producing electric and hybrid vehicles.

The Saleen S320E Mustang

Saleen is one of North America's premiere specialty vehicle manufacturer. They are well known for the incredible Mustangs that they deliver to consumers. Each and every vehicle that they produce is one that many of us would love to get our hands on because of the craftsmanship, performance, and power that is put into it.

The 2008 S320E Mustang has been equipped with a 302 cubin inch engine that was specially made by Saleen and has been augmented with a patented Saleen twin screw and intercooler supercharger. With this engine the S320 can produce 620 horsepower and 600 pound-ft of torque.

"We believe that we are in the process of creating a legendary new car. It's thrilling," says Saleen President and CEO, Paul Wilbur. "It seemed to make sense that as we go into our 25th Anniversary as a manufacturer in North America that we make our best and most powerful car yet."

This new model - which has also been given the name "Extreme" - has been built with a number of high quality performance parts that reveal to consumers the race engineering heritage that they are known for. The unique engine that is placed inside the car is a forged crankshaft with forged connecting rods and forged pistons that have been blueprinted individually. It is also built with 5 axis CNC aluminum cylinder heads, high performance camshafts, and high flow fuel injectors.

Each one of the parts work together simultaneously with the Saleen twin screw supercharger. It is connected to a 6 speed manual transmission and Max grip rear differential - which allows it to reach from 0 to 60 mph in less then 4 seconds.

"This place represents a kind of automotive "mecca" for me. We are making limited volume, performance vehicles for people who really love cars, by people who really love cars. I cannot think of a better place to put my 35 years of OEM engineering history to work," says Vice Chairman and Chief Technical Officer Chris Theodore. Chris Theodore is also known as the father of the Ford GT. "Now I am helping build great Saleen cars in the same factory that I architected for the legendary Ford GT."

"This is the best motor that we have ever done," says Powertrain Engineering lead Rob Simons. "We have really benefited from having Chris [Theodore] around. He brings perspective and experience to the company unlike anything that we have known prior."

In order to get the best performance out of the this Saleen Mustang the engineering team used a standard 20 inch, 5 spoke forged aluminum allow wheels that are wrapped in Pirelli P-Zero Rosso tires. But in order to have large amounts of power added to the car you must be able to control it. Otherwise we would be all over the road with it. To have the type of control that we need engineers equipped the Extreme with a Saleen Racecraft suspension and a second generation, brand new Watts Link system that will help the driver stay in control of the vehicle when taking sharp corners.

The chassis system has been rounded by upgraded 4 wheel disc brakes and ABS and traction control. The performance brake system features 15 inch vented, slotted rotors, with 6 piston calipers in the front and 11.8 inch rear vented discs with single piston calipers in the back.

Nissan R35 GTR - Super Car Or Not?

The Nissan GTR has always been a vehicle that stands for extreme performance. What most people don't realize when they think about this machine is that it has always been a well rounded type of performance car. The new R35 GTR has been injected with the same DNA as the previous R32, R33, and R34 models. This means that the car will have extreme performance and also practicality to meet the demands of anyone's lifestyle. Nissan describes the new R35 GTR as a multi-performance sports car meaning that it's not just another fast car with all the right numbers that look great in magazines.

The main question about the R35 GTR would be, "Is it a super car?" The fact that this question has been brought up makes me happy to see that people realize there is more to a super car than just the numbers generated from performance tests. When I think of a super car or at least what a super car has been up until now would be something that is fast, stimulating, violent, loud, and visually attractive on an extreme level. The GTR without a doubt is fast, and not just in a straight line. This vehicle took out top level Porsche models and also gave the lightened Gallardo a run for its money on Tsukuba circuit in Japan. It also clocks one of the best times on Germany's Nurburgring for a production car which is a better reference than a tight circuit like Tsukuba. With these accomplishments it can be said that the GTR has great power, braking, and cornering abilities that either match or rival cars that are considered super cars.

It's as fast as a super car, but that's not enough. My opinion is that it doesn't fall short of being called one, it just falls somewhere else. A super car is just a category, it doesn't necessarily mean better. The R35 is better than a super car, but the things that make it better would be the only reasons why someone would rather not buy it. It's a useful machine, meaning that it can get you to work in any condition and can be driven all year round through any rain or snowstorm. It has space for passengers and luggage. It's quiet enough to drive down the street at 2am without the neighbors hating you. It rounded and can visually fit in with the rest of the cars on the road, especially 350zs and G35s. These are all great qualities, but not the types of traits that the type of person that will buy such an item is looking for. Most people that are in the market for a vehicle like this are looking for one thing and one thing only, extravagance, both in the looks, and the driving characteristics of the car.

The fact that most of this machine's testing was done on the Nurburgring says a lot about it. Nurburgring is a demanding circuit that requires a car to be setup to be both fast and safe simultaneously. The ideal car at this circuit would be something that makes the driver feel safe while clocking amazing times. One lap around this course in a real super car would make most people have a heart attack before they got halfway through, but in this car anyone can do a few laps in a row without shaking too much while traveling at the same speeds. The R35 is a perfect ultra high performance street car designed for the average driver. Certain pro racing drivers like Keiichi Tsuchiya drove this car and did not like that fact that it had so many computers that take away control from the driver, saying that the car felt "unnatural" at its limits. What a pro doesn't realize is that the average driver that doesn't practice on the track daily is happy to return some driver control responsibilities back to the car so he or she doesn't have to worry while they rush to work or have some fun of winding roads during their weekend off.

Even though the R35 is not a super car, it is still something different that sends a positive message to people about the advancement in automobiles. Sure it's not raw enough to be a pure sports car like the NSX R or Porsche GT3 that are designed for driving enthusiasts that want to be stimulated, but I believe that Nissan wanted to show the world what they are capable of doing in terms of drivability technology with this car. Pure sports cars are generally fast because they are stiff, lightweight, and responsive, much like racing cars driven by professionals off the streets. The GTR weighs almost 2 tons meaning that the secrets to its speed are not so simple. The R35 can be considered to be a beast with manners that was built to appeal to everyone. It may be a little too cheap for the status driven upper class and a little too pricey for the current 350z, Evo, and STI owners. A car's price says a lot about it and for only $80K, I would say that it should be higher to match the lower numbers that it generated during its performance tests.

Tips to Help Improve Your Car Audio System Dramatically

Car audio components are being improved each passing day to upgrade sound systems. If one does not opt for these improved components, then one might just be living in the past. These improved components add greater functionality to your car audio system.

These components are speakers, subwoofers, tweeters, amplifiers, ipod adapters and more. All these add another dimension to your audio system. You have the option of settling for your factory installed system, however, aftermarket systems are massively superior to factory systems. But that's by the way.

To take your car audio to another level, you'll need to add new speakers, upgrade your receiver, add tweeters, add an amplifier, install vibration dampers like dynamat, install bass blockers on your full-range component speakers, add equalizers and other signal processors -- the list goes on...

Adding new speakers to your audio system will alter your setup most dramatically (if done right). This is because your speakers are the most important units in your car audio set up. Also know that you need to add such that will fit your vehicle. This will prevent sound inbalance or damage to your audio system. What you install is what you get. If you install old age-stricken stuff, then you get old age-stricken sound.

Adding tweeters to your sound system improves your listening experience. A tweeter takes care of those sizzling highs that cannot be catered for by regular speakers. A crossover will help make your output stage a lot better.

Upgrading your receivers will ensure better sound and less distortion. This could include adding additional music sources like a portable DVD, a satellite radio tuner and more; through an auxiliary input.

You also need vibration dampers. Dynamats absorb the vibration caused by your car speakers and road noise. When these vibrations are absorbed, you can conveniently hear the music that comes out of your sound system without background noise.

If you're in for the best sound, you'll need to add a bass blocker. Installing bass blockers on your full range component speakers simply help to block the bass frequencies that your speakers cannot handle. They are installed on your speaker's wire. This helps remove distortion from your music.

Other steps you could take to improve your car audio output include making sure your subwoofers and speakers are in phase, changing the position or enclosure style of your subwoofer and avoiding extreme bass control boost.

Your subwoofers and speakers wired in phase helps give more balance to your sound. Make sure the positive and the negative sides are wired accordingly at both the receiver and the speakers.

Changing the enclosure style of your subwoofer actually depends on the type of bass sound you prefer. Some prefer a boomy bass; others prefer a low frequency bass. The position of your subwoofer will determine that.

Avoiding extreme bass control boost and turning up your volume instead will give less distortion to your signals.

Implement these and your car audio will never remain the same.

Rangkaian 1,5V Earphones Audio Amplifier

This audio amplifier circuit, connected to 32 Ohm impedance mini-earphones, can detect very remote sounds. Useful for theatre, cinema and lecture goers: every word will be clearly heard. You can also listen to your television set at a very low volume, avoiding to bother relatives and neighbors. Even if you have a faultless hearing, you may discover unexpected sounds using this device: a remote bird twittering will seem very close to you.

The heart of the circuit is a constant-volume control amplifier. All the signals picked-up by the microphone are amplified at a constant level of about 1 Volt peak to peak. In this manner very low amplitude audio signals are highly amplified and high amplitude ones are limited. This operation is accomplished by Q3, modifying the bias of Q1 (hence its AC gain) by means of R2.

A noteworthy feature of this circuit is 1,5V battery operation.

TA8215 IC

R1 with R2 forms a voltage divider that attenuates the input signal by 24dB. Considering the chip's 50dB gain, that still leaves 26dB overall gain, slightly more than enough to fully saturate the amplifier when the sound card works at maximal output. C1 blocks DC at the preamplifier input. C2 is the ground return of the feedback circuit. These two capacitors need to be in the ratio shown, in order to suppress switching clicks when powering the circuit on and off. The output pins 15 and 16 are connected directly to the speaker, while C7, R6, C8 and R7 provide the proper load phase shifting to avoid high frequency instability.

The power supply is decoupled with a rather small 100uF capacitor. That's enough for higher frequency decoupling, and at lower frequencies anyway the large capacitors in the PC power supply are fine. Pins 10 and 17 supply the power amplifiers, while pin 9 provides power to the pre stages. This power is filtered by C3. The power control pin 4 allows to shut down the amplifier, an option not used here, so it's tied to 12V. Pin 1 is a muting input, also not used, and left open.
