  • DeLorean: why is it so special?

    John Zachary DeLorean: A Man Who Brought Change to the Auto Industry

    You probably know what a DeLorean car is if you have seen Back to the Future. However, what you might not know is the story behind John DeLorean! Continue reading to learn about John Z. DeLorean’s life and how he moved up the corporate ladder!

    DeLorean’s Beginnings

    In January of 1925 in Detroit, Michigan a boy with the last name “DeLorean” was born. When DeLorean was young, he was mechanically talented and tinkered with just about anything. After secondary school he attended the Lawrence Institute of Technology and eventually earned a master’s in engineering from the Chrysler Institute.  After graduating, he worked at the Packard Research and Development group for a bit but later left for a job at General Motors.

    Hard times for DeLorean

    The early 1970s were tough times in Detroit and DeLorean in his autobiography, DeLorean, said that the ethical and business problems he had with General Motors had become so serious, that he wanted out. Truth be told, this let him turn into a well-paid independent consultant whereby he could obtain money build his own dream car.

    In the mid-1970s DeLorean founded two companies: Composite Technology Corporation (CTC) and the DeLorean Motor Company (DMC).  He created CTC to research and create new, automotive construction material.  Many of those materials were DeLorean’s projects at GM and involved composite materials and construction techniques. Many of those CTC products found their way into DeLorean vehicles!

    DeLorean Attempts to Get His Dream Car Out

    To build his first dream vehicle, the DMC-12, DeLorean hired Giorgetto Giugiaro. For a location DeLorean settled on Northern Ireland, which gave him the best business deal. His factory’s opening was in 1981. As many automobile enthusiasts may know, the first 80 or so cars to roll off the assembly line were so terrible they were unfinished and then parked along the factory’s fence for weeks. DeLorean tghen set up rebuilding facilities on the East and West Coasts of the United States, just to fix completed cars before they could be brought to dealers!

    Despite his setbacks, though, there were orders for hundreds and hundreds of DMC-12s. DeLorean tried to ramp production up to 14,700 a year to meet demand, however, financial problems came about. In 1982, the DeLorean Motor Company was put into receivership by the British government in because he was desperate, DeLorean pursued “questionable sources of funds” to keep his company afloat. DeLorean wound up in a serious DEA cocaine bust in October 1982 that became a news story. By 1984, he was found not guilty of every count against him, but his company had disintegrated by then.  DeLorean passed away in March of 2005 at eighty years old. This happened in Summit, New Jersey.

    DeLorean’s Impact & His Impact on Today’s Vehicles

    Today, the DeLorean Motorcar legend is still alive because of the DeLorean Motor Company in Texas.  They bought the DeLorean trademark and many of the original parts left behind when DeLorean’s company fell apart. Today, you can purchase 100% remanufactured DeLorean automobiles from the DeLorean Motor Company.

    Thank you to the Service Manager at Hiley Volkswagen of Arlington, a full-service local VW car dealer in Arlington, TX, for chatting with us about John DeLorean and his contributions to the automotive industry!

     

     

  • Even the mightiest of cars should bear good tires. Here’s why!

    Are Your Tires too Old to Be Driving on?

    Of all your car’s parts, its tires have the greatest effect on the way it handles and brakes. Unfortunately, failures of older tires have resulted in fatalities. Thus, it’s important to keep an eye on your tires! The investigation into the accident’s cause that killed actor Paul Walker in 2013 revealed that the Porsche Carrera GT he was riding in had nine-year-old tires. The California Highway Patrol indicated that the tires’ age may have compromised how they handled.

    For years, drivers have relied on the tread depth to judge the condition of a tire. But the rubber compounds in a tire wear out with time, regardless of the tread’s condition. An old tire can be a safety hazard. For some people, old tires will never be a problem. If you drive somewhere around 12,000-15,000 miles each year, a tire’s tread may wear out in three to four years, before the rubber compound does. But if you only drive around 6,000 miles a year, aging tires may be an issue.

    Rubber bands may illustrate the point. Everyone knows that rubber bands age poorly and will develop cracks within a couple of years. That’s essentially what happens to a tire. Cracks in their rubber start to develop over time. They may appear on the surface and inside the tire, too. This cracking can eventually cause the tread’s steel belts to separate from the rest of the tire. Hard use can accelerate the process.

    How to determine a tire’s age

    SEE ALSO: speedART team showcases a neatly revised Porsche vehicle. Check it out!

    Tires made after the year 2000 have a four-digit DOT code. The first two numbers represent the week of the year in which the tire was made. The second two represent the year of make. A tire with a DOT code of 1207 was made in 2007’s 12th week. Check tires once in a while for any sign of aging, such as tread distortion, or small or large hairline cracks in the sidewall. According to the Service manager at Hiley Mazda of Hurst, a local full-service car dealer in Hurst, TX, vibrations may also be an indicator of aging problems.

    How long a tire lasts for

    If living in a warm climate, you may want to pay special attention to your tires. The National Highway Traffic Safety Administration (NHTSA) has found that tires deteriorate quicker in warmer climates than cooler ones. Do you live near the coast? Keep that in mind when monitoring the condition of your tires. Are you using a spare tire? Well, avoid storing it in the trunk. It will get really hot in there.

    However, the NHTSA doesn’t have any specific guidelines on tire aging and defers to the recommendations of tire manufacturers and car makers. Some carmakers such as Mercedes-Benz and Nissan tell people to replace tires six years after their production date, regardless of their tread life. A few tire manufacturers, such as Continental and Michelin, say that a tire can last up to ten years when a driver has all the proper maintenance done as per their vehicle manufacturer’s recommendation.

     

     

     

  • Is there anything else we can expect from the Durango lineup?

    2016 Dodge Durango ConceptHemi Durango in The Works?

    FCA went into SEMA show in Las Vegas this past year hoping to show off some of their new concepts, designs, and had hoped that something might stick. Well one concept truly did stick with the audience and the internet when it was shown off, and that was the bright blue Durango concept, which they called the “Durango Shaker”.

    Shortly after the revealing it was reported by major news outlets that the extremely positive reaction to the Shaker concept had stirred the parent company of Dodge, FCA to put major consideration into the development of this concept Durango.

    While most other automakers are looking to go away from power, and more towards efficiency, Dodge has remained set on providing car buyers the power they feel they crave. We have seen this with the Viper models, the SRT models, as well as the remake of the Charger & Challenger vehicles. Aggressive styling, and pure power.

    SEE ALSO: Dodge Releases Two Appearance Packages for 2016 Durango Model

    There have been rumors stirring about for quite some time that they would introduce a SRT version of the Durango, mostly because of how underperforming the Durango had done in recent years, when compared to the king of SUVs their sibling under the FCA umbrella, Jeep. So why not add something unique to it, give it something that is hard to resist.

    We took the time to look at the inventory of Dodge Durango from a local Oklahoma dealer, Ada Dodge. What we saw wasn’t a SUV that was lacking power or design, it just needed a step up from itself. Something that made the Durango name live on, and that will surely be the Shaker concept.

  • A Mercedes sedan touched by AMG: brutally powerful and sexy

    2016 Mercede-AMG E 63 4MATIC+And here it is: the latest AMG project is brought to life. Yes, we are talking about the fresh Mercedes-AMG E 63 4MATIC+ and the E 63 S 4MATIC+ babes. Aren’t they sweet? Along with the super-mega-titanic power output and the exceptional Mercedes-Benz and AMG quality that we are all aware of, these two vehicles will try to be different in a particular way.

    Of course, one of the many ways of maintaining interesting is refreshment of the exterior styling. Definitely appealing and sexy, these two bad boys feature sporty front face with distinctive A-pillar and for the first time AMG team gears a Mercedes-Benz saloon vehicle with a bonnet that is inset between the wings and bumper, just like a coupe model. Another way of expressing sexiness is by adding wide front apron, inspired by the design of a jet wing and a large front splitter.

    The sides catch the eye with numerous elemets. However, one super distinctive is the arrow-shaped wing signet, covered in silver chrome. Also, the side sill panels make the vehicle look even lower than it actually is and contribute to the aggressive and sporty appearance. And all this is topped with exclusive 10-spoke light-alloy wheels in titanium grey with high-sheen finish. Sweet.

    2016 Mercede-AMG E 63 4MATIC+

    And last, but not least, the rear showcases muscles and confidence, expressed by the defined spoiler lip in body color, rear apron with diffuser-look inser and two chrome-plated twin tailpipes. S 63 S 4MATIC+ also features a trim strip on the rear apron.

    The muscular rear end provides the finishing touch in conjunction with the clearly defined spoiler lip in the colour of the vehicle on the boot lid, the rear apron with diffuser-look insert, and the two bright chrome-plated twin tailpipe trim elements on the selectable sports exhaust system. The E 63 S 4MATIC+ also features a trim strip in silver chrome on the rear apron.

    And what about the interior styling?

    Drivetrain system

    Long story short: 4.0-liter twin turbo V8, mated to a MCT 9-speed sports gearbox. But let’s see the long story, shall we? Along with the extremely high power output, measured at 612hp (450kW) and 850Nm of torque, the powertrain has some more neat tricks. For example, the cylinder deactivation system and two twin-scroll turbochargers, applied for the first time in Mercedes-AMG vehicle.

    2016 Mercede-AMG E 63 4MATIC+

    The gearbox is also worth mentioning. This is a super-fast and exclusively fine-tuned system, especially developed for th E 63 4MATIC+ and the E 63 S 4MATIC+. It comes with special software that allows super short shift times and super fast multiple downshifts. Furthermore, it also comes with a wet start-off clutch that replaces the torque converter. In this way AMG engineers reduce the overall weigth of the vehicle and optimize the acceleration responsiveness. Cool.

  • What would a love story between G-POWER and BMW bring us? Tons of power

    2016 G-POWER BMW M3 TwinPower Turbo G-POWER team has decided to tweak a rather sexy BMW vehicle  and make it deliver a bit more horsepower. How much exactly? Extra 150hp. Or, in other words, the sweetheart now delivers a total of 600hp (441kW).

    Also, there are some additional drivetrain tweaks and additions. For example, the team has geared the BMW M 3.0-liter TwinPower Turbo with exclusive titanium exhaust system, new downpipes, rear ailwnxwe box and more.

    In fact, one of the most notable features is the revised fuel, spark and boost mapping, all exclusive and fine-tuned just for this bad boy. What is also special about the tweaking process is that the engineering crew has used G-POWER Bi-Tronic 2 V3 electronic control unit remap that is calibrated to each individual vehicle engine system for optimal results. Cool.

    2016 G-POWER BMW M3 TwinPower Turbo

    But let’s talk about the engine power itself. The super comprehensive engine modifications include aerodynamic-tweaked turbine wheels, flow-optimised CNC-machined turbines and compressor housings. This all results in efficient use of the generated 600 horsepower and the significantly increased 740Nm of torque that altogether aid the lucky BMW vehicle to reach 100 km/h (62mph) in mere 3.5 seconds and chase a top speed of 320km/h. Incredible, isn’t it?

    SEE ALSO: G-POWER surprises with stunning Mercedes-AMG G63 conversion

    However, for those of you (if there are any at all) who do not want to get the maximum of the setup, G-POWER team offers a kind of basic version that offers a total output of 520hp (382kW) and 700Nm of torque with a selection of Bi-Tronic 2 V1 ECU remap or the Bi-Tronic 5 V1 external power module.

    2016 G-POWER BMW M3 TwinPower Turbo

    The middle choice offers 560 horsepower (411kW) and 720Nm via the same Bi-Tronik 2 V2 remap or the Bi-Tronic 5 V2 system that works with the additional exhaust downpipes, but this time without the catalytic convertors.

    Additional goodies, available with all the power system choices include special chassis fine-tuning, special G-POWER GM4-RS coilover suspension, low unsprung weight and neat HURRICANE RR forged double forged design wheels. We do like it.

  • Toyota and the TNGA architecture: it slowly becomes a trend. But a good one!

    2017 Toyota C-HRArchitecture in vehicles. Yes, this again. I know it has become something as a trend, but stick with me. Toyota is the next big player to incorporate signature body architecture in its vehicles and as it seems, the team tries to stand out from the crowd pretty hard. So, let’s check out what’s the idea of the masterminds behind Toyota.

    2017 Toyota C-HR

    Both latest generations of Prius and C-HR will be dealing with a thing called Toyota New Global Architecture (TNGA) and the idea is that these two vehicles open the gates to a world of Toyota vehicles based solely on this platform. The TNGA thing itself will try to redefine the approach towards vehicle manufacturing and driving utility.

    Our thoughts about the latest Prius you can find on this link

    The TNGA C-Platform thing that debuted with the latest Prius allows for tailor-made changes to be executed, along with optimized drivetrain system and more precisely super-optimized and fine-tuned suspension system. It also adapts the wheelbase to better handling and responsiveness. Sweet.

    Out thoughts about the latest C-HR you can find on this link

    Of course, the whole idea is to deliver new breed of models that are not only super-adaptive and featuring cutting-edge technologies, but also offer better handling response, consistency of response and delivering way more confidence for the driver. Furthermore, one of the main benefits of the TNGA C-platform is the lower center of gravity. This directly contributes to better handling, more stable turning and less body roll.

    So, is it worth it?

    2017 Toyota C-HR

    TNGA platform is claimed to be 65 per cent more rigid than the previous C-segment platform. It provides solid base for developing and tuning the suspension system, all along with numerous engine components. Also, as it seems, the new C-HR and its owners feel happy and confident on the road. So, we do presume that this is a step in the right direction for Toyota. But let’s be clear about it: time will show whether this is a cheap trick or a revolutionary in the history of the brand.
