'Temporary atomic connections ensure high tyre adhesion'
http://eurekar.co.uk/articles/2015-10-19/continental-spices-tyres-with-black-chili Continental spices tyres with Black Chili Stewart Smith 2015-10-19 I'VE just returned from what petrol heads would give an arm and a leg to experience - driving six top range, high performance motors on a 300-mile motoring adventure in Southern Spain. The invitation from Continental Tyres, Europe's biggest makers of the black stuff, was to test their latest compound called Black Chili which has been specially designed for top end ultra high performance cars and the company's new ContiSilent tyre. And what a line-up of gleaming performance motors greeted us at Conti's venue for the event, the La Cala Resort near Marbella. How's this for a dream team of motors: Jaguar F-Type, Mercedes CLA AMG, BMW M4, Porsche Macan S, Chevrolet Corvette C7 Stingray [ice] and Tesla Model S [EV]. All were fitted with ContiSport tyres, including the latest SportContact 6 and the all-electric Tesla boasted the ContiSilent. Over the years I've attended several tyre testing events, which are usually held at centres under strict, controlled test conditions. This Conti event was held under real life conditions with all the driving taking place on public roads in twisty, demanding mountain roads with hardly a straight to be encountered. To say it was great fun is an understatement! Driving to near the limit on such roads can be a bit nerve-wracking, but with these new Black Chili tyres under us they gave us confidence when tackling the hundreds of hairpin bends over the two-day event. The grip was amazing and only when pushed a little too hard did we feel any rear end slippage or over or understeer. Continental engineers said the Black Chili rubber compound is designed to mesh with the roughness of the road. At the same time, temporary atomic connections between the tyre compound and the road surface ensure high adhesion, acting like small suction pads. Both factors make for the greatest possible adhesion in all directions - during braking, cornering, and acceleration on both wet and dry roads. I'd driven most of these supercars before, except the Jaguar and the Tesla and my first experience of the F-Type was an eye-opener ... It was fitted with 20-inch wheels and ContiForceContact tyres which gave fantastic adhesion on the twisty roads we were on, and despite the speeds we achieved, I never once felt the top sports car was in danger of losing grip. The star of the show for me was the American all-electric super car, the Tesla [EV]. It's a big motor, but the battery-powered Model S can hit 62mph from standstill in just 5.4 seconds. And unlike the internal combustion engine with hundreds of moving pieces that spark, pump, belch, and groan the Tesla model has only one moving piece, a rotor. As a result you put your foot down and acceleration is instantaneous and in seconds it is hitting 70. I did enjoy the experience. The Tesla was fitted with the new ContiSilent tyres that not only demonstrate top performance but are also quiet, helping to increase car comfort. The secret of ContiSilent is a coating that is bonded to the inside of the tread area after the tyre production process. This special layer of foam has a strong damping effect on the sound waves caused by the rolling tyre, so that no matter what surface the vehicle is driving on, the noise level reaching the cabin is substantially reduced ...

Yes, this can only mean Continental Tyres’ Black Chili Driving Experience. The event allows the tyre giant to showcase its ultra high performance tyres, all made using a special “Black Chili” compound. The “Black Chili” tyres were fitted to an exciting blend of fast cars – a Jaguar F-Type, a 100% electric Tesla Model S and the iconic Corvette C7 Stingray. Three very different German cars made up the pack – a Porsche Macan S, Mercedes CLA 45 AMG and a BMW M4 cabriolet. Follow our journey below… Our chariots await. It’s Day 1 and time to leave our base at the La Cala Golf Resort, Mijas (about 30 minutes from Malaga airport) for our first foray deep into Andalucia. In two days, we drove for some nine hours over more than 300 miles. It wasn’t a race – it was staged on public roads and all the usual rules applied. We all paired up and shared the driving. Scenic doesn’t do Andalucia justice ... Fitting the wrong tyres to a car can make a surprising difference, affecting handling, grip, smoothness and road noise. Apparently the “Black Chili” tread compound ensures optimum adhesion when pushed to the limits. The rubber compound is designed to mesh with the roughness of the road. At the same time, temporary atomic connections between the tyre compound and the road surface ensure high adhesion, acting like small suction pads at a microscopic level. You may think the Tesla is a odd choice for the fleet, but the simple fact is that it may be electric, but it can more than hold its own. Big, beautiful, very refined and capable of 0.62mph in 5.4 seconds… it has prodigious torque. And Contintental has played its part in the Tesla success story. As standard, the car is fitted with ContiSilent tyres where the inside of the tyre is covered with a special foam material, reducing interior noise by up to nine decibels ... El Torcal Park Nature Reserve The El Torcal Park Nature Reserve (el Paraje Natural de El Torcal) – the most geologically stunning of all Andalucia’s natural parks ... The Black Chili Driving Experience was more than just a chance to drive fast cars. It’s reminder that tyres are the unsung heroes of the motoring world. Often just a “distress purchase” after a puncture or MoT failure, manufacturers such as Continental can spend as much as four years working on the development of a new car from concept to showroom. Safety is paramount, but economy, handling, refinement and grip also come into the equation.
