A beat-up old diesel hatchback and a gleaming, showroom-fresh hybrid supercar. These two vehicles are worlds apart in performance, quality and price, yet they have one thing in common: tyres. These four rubber rings represent your only, palm-sized contact with the surface upon which you’re driving, and no matter how good your car, if your tyres aren’t up to scratch, you’re running the risk of having a serious accident. Low pressures, barely legal tread depths and cheap rubber are all issues faced by motorists, although the addition of tyre pressure-monitoring systems (TPMS), which were made mandatory from 2012, has helped to improve safety. However, that still hasn’t cured all tyre problems completely, and rubber defects rank as one of the biggest reasons for MoT failure in the UK. Despite the lack of attention afforded by drivers, tyre companies are ploughing millions into research and development to make them perform to their peak. So what has this achieved, and what will the future hold? With every part of a car becoming more connected, why not tyres, too? Perhaps we really could see someone reinvent the wheel. To find out about the tyre revolution, Auto Express headed to Goodyear’s headquarters in Colmar-Berg, Luxembourg. It’s more than just a factory; it’s more like Goodyear city, with 3,000 employees representing more than 50 nationalities – that’s 15 per cent of the company’s global workforce, with the rest based in the USA, Germany and, since 2015, China. In Luxembourg, workers are split across a test track, production line, mould plant and innovation centre. Our focus is on the latter, which features the design studio – where the latest prototype tread patterns are penned – and the compound lab, where experts tinker with chemicals to produce the perfect mixture that combines grip, rolling resistance and durability. It’s from the minds of these experts that Goodyear has produced some radical ideas. First was the BH-03, which used the heat and movement of the tyre to generate electricity – a vital step to fitting on-board electronics to relay information about the condition of both the rubber and the road. This was moved on further with the CityCube tyre, designed specifically for the Toyota iTRIL concept. It can identify road conditions and transmit this data to the vehicle to support accident-prevention systems on board. Then there’s the Eagle 360, revealed in 2016, which replaces the traditional tyre shape with a bold and innovative spherical design. It was unlike anything seen before, and for 2017 Goodyear – along with design agency Rubica – went one step further by creating an urban vehicle around the Eagle 360 tyre. The spherical tyre has a ‘brain’ that can morph its bionic skin into tread to suit the surface. The artificial intelligence can also allow autonomous maintenance of the tyre – and the vehicle to which they’re fitted. Add in vertical and horizontal running to boost manoeuvrability, and the benefits are huge. Goodyear is keen to point out that we shouldn’t start getting too far ahead of ourselves just yet, though, as these type of concepts won’t actually be in production for at least another 20 to 30 years. Herman Vereecken, manager of communication strategy and deployment at the innovation centre – who’s worked at Goodyear for 32 years – explained that the firm is currently working on manufacturer projects for 2018/19. These products will then have life cycles of six to seven years, so conventional tyres will still be fitted on new vehicles until at least 2025. Vereecken said: “This is new technology beyond that. For 100 years tyres have been material and mechanical, but now we’re getting an electrical dimension, and that’s exciting. It’s something that’s a revolution in the tyre industry. Electrical components in tyres is the future.” There’s no doubt, though, that the world of tyres is changing even now, just in a slightly more subtle way than having a spherical ball strapped to each corner of your car. Run-flats marked the first development of advanced technology, but now with the industry driven by lowering CO2 emissions, changes will come faster than ever Romain Hansen, director of technology projects, said: “We will still see vehicles that look like those that we are used to. They will use smaller tyres, and I can foresee tyres having to carry heavier loads because the vehicles of tomorrow will be heavier due to battery packs. “In the longer term, vehicles will look different so we can have different looking tyres. Tall and narrow at first but then ultimately the sphere.” Tyres have a huge role to play in autonomy too, with chip-in-tyre technology being developed further. Hansen continued: “If a tyre can tell the car about the road it can be very beneficial from a safety point of view. It’s not only informing, it’s using algorithms to create values to optimise safety and performance.” The message from Goodyear is clear – if we can’t or won’t look after our own tyres, then it’ll make sure its systems can do it for you to make sure we’re all driving around safer – no matter what the tyre might look like. How to design and produce a tyre You might think a tyre is a circular piece of black rubber, and wonder how much can you change that? The answer is really quite a lot. We spent time with senior industrial designer Sébastien Fontaine, who talked us through the process of bringing a new tread pattern from sketchbook to production line. The whole journey takes around two years and starts with an inspiration wall, featuring concept cars and images of nature and other topics. From here, designers will sketch a range of tread and sidewall designs, narrowing it down to around 15. Experts and engineers will then pick four or five to continue along the process. These will then be modelled on 3D computer software, running simulations for contact patches and tread pattern effectiveness. Prototypes will then be made of three designs and tested with a huge variety of compounds, before being fine tuned and ultimately rolled out for sale. So what of those compounds? First of all, it’s not just rubber. The ingredient list reads as follows: carbon black to give colour and work as a lubricant, natural and synthetic rubber and silica which give the balance between rolling resistance and braking balance. Changing the mix by just a few per cent can give vastly different characteristics, with each compound run through hundreds of test cycles before being formed into a tyre. The addition of sulphur to the mix is also a vital component to create the 150-degree Celsius process known as vulcanisation – developed by Charles Goodyear in the 1800s – which helps the rubber take shape. The Goodyear plant can mix around 300kg of these compounds in 90 seconds, before leaving it to cure for eight minutes. The rubber is then fitted around a carcass of polyester and steel before being put in presses to mould the detailed tread

Two U.S. fighter jets intercepted four Russian aircraft off the coast of Alaska on Wednesday, including two Russian fighter jets, for the first time in years, North American Aerospace Defense Command (NORAD) said Thursday. Two U.S. F-22s intercepted two Russian Tu-95 Bear bombers and two Su-35 Flanker jets on Wednesday afternoon, said Lori O'Donley, a NORAD The Russian jets remained in international airspace, she added. U.S. planes intercepted Russian bombers several times last month, the first time Russia had conducted flights of that nature since 2015. The incidents piqued public concern, though the Pentagon has said they're considered routine. Last month's incidents, though, did not include Su-35s. The last time Su-35s accompanied bombers on such flights was 2014, O'Donley said. "This wasn't anything unlike what we saw a couple weeks ago other than the fact that the Su-35s were there," she said. In April, the Pentagon suggested the Russian bomber flights could have been part of testing for the long-grounded aircraft. "I can't divine their intent; it's certainly well known that they had some maintenance problems with this particular type of bomber and grounded them for some period of time," Pentagon spokesman Capt. Jeff Davis told reporters. "That may explain the hiatus in them doing it."

Welcome to CSBD. Enjoy have fun .

The 2017 Camaro ZL1 is poised to challenge the most advanced sports coupes in the world with unprecedented levels of technology, refinement, track capability and straight-line acceleration. In the Middle East, we will be able to ride the most powerful Camaro in history, and learn the real value of big power, big noise, and total control in the first half of 2017. The ZL1 delivers significantly enhanced performance in a more aggressive body and a lighter architecture. Needless to say, sports enthusiasts won’t be disappointed, as the supercharged coupe delivers more power than any other Camaro to date and features the most comprehensive aerodynamic package. And the fact that it is about 90 Kg lighter than its predecessor adds to the thrill and sets a new benchmark in the supercharged muscle car market Super aggressive attitude The 2017 Camaro ZL1 sports an excellent stylish design which gives the car a purposeful, super aggressive attitude. The sports car sits on unique, staggered 20-inch forged aluminum wheels wrapped in Goodyear Eagle F1 SuperCar tires. “The Camaro ZL1 is designed to excel at everything, delivering on design, dependability, quality and performance,” said Abdallah Madhoun, Regional Sales and Marketing Manager for Chevrolet, GM Middle East. Functionality defines the Camaro ZL1’s form, with the exterior shaped during more than 100 hours of wind-tunnel testing and on-track validation to improve aerodynamics and cooling for track use. Accordingly, its exterior elements all play a part in managing airflow over, under and through the ZL1. The lower grille opening, for example, offers greater airflow compared to the Camaro SS, and the upper grille incorporates a new version of the “flow-tie” open bowtie insignia. There’s also a new hood, with a carbon fiber insert and heat extractor that pulls hot air from the engine compartment. Inside, there are standard Recaro front seats, along with a suede flat-bottom steering wheel and shift knob. Chevrolet’s Performance Data Recorder is available. 0-100 Km/h in 3.6 seconds The ZL1, available as a coupe and a convertible, shares with the Corvette Z06 its herculean power-plant, the supercharged LT4 6.2L V-8 engine. It is rated at 650 horsepower and 650 lb-ft of torque (881 Nm), making this the fastest Camaro ZL1 in the vehicles 50 year history. Its 0-100 Km/h time is a mere 3.6 seconds, and it can complete the quarter mile in 11.4 seconds at a speed of 204 Km/h. The Camaro ZL1 is the first production car to use a new, advanced 10-speed automatic gearbox, which offers strong economy and performance benefits. It is also available as a six-speed manual. Customized launch control The 2017 Camaro ZL1 comes standard with customizable launch control, which allows drivers to adjust launch rpm and wheel slip to dial in the perfect start. Moreover, a cohesive suite of performance technologies tailors ZL1’s performance for street and track. Features include an updated Magnetic Ride suspension, Performance Traction Management, electronic limited-slip differential and Driver Mode Selector. It also has a stronger power-to-weight ratio than its predecessor, weighing 200 pounds less, while offering approximately 60 more horsepower and 80 more pound-feet of torque. The result is a one-of-a-kind driving experience. Best of the best Finally – and unlike some competitors – there’s no need to purchase an optional package to make the ZL1 track ready. Track capability comes standard, with features including an impressive 11 heat exchangers for optimal powertrain cooling. Camaro ZL1 should scare the best of the best.
