2019 Buick Envision First Drive: Disposer Closer

  2019 Buick Envision First Drive: Disposer Closer Spiffing up Buick's middle child to capture Encore trade-insBuick might need to work on its euphemism-speak. In his pitch for the newly freshened Buick Envision, marketing boss Sam Russell referred to Encore lessees and buyers trading in their subcompact utes as "disposers." Yikes—surely those vehicles are still useful, if the J.D. Power Dependability rankings are to be believed. The subject came up by way of explanation of Buick's motivation to spiff up its midsize luxury crossover, the 2019 Envision. Apparently 60 percent of Encore buyers have been new to GM.

The new Goodyear EfficientGrip Performance with Electric Drive Technology doesn't exactly have a catchy name, but it has an interesting purpose. It's one of the first tires designed specifically to deal with the needs of powerful plug-in hybrid and electric cars.

  The 2019 Subaru Ascent Can Tow 5,000 Pounds and Seat up to Eight The Subaru Ascent tows like no Subaru ever could before it, thanks to a new engine and stout CVT.On Thursday, Subaru announced the specifications of its upcoming SUV, the Ascent. Pricing, options, and capabilities are detailed, the most extreme of which is the Ascent's towing capacity of 5,000 pounds, greater than that of any other Subaru ever made.

Goodyear claims to have a solution with a new tire aimed at the electric vehicle market. High -Load-Carrying Construction: The tire cavity shape has been optimized to support the additional In addition, the sidewall has been designed to reduce aerodynamic drag and the profile yields less rotating mass

The company found through testing that EVs wear out traditional tires up to 30 percent faster than conventional vehicles. It's a combination of the instant torque and the extra weight from lugging batteries around.

“The combination of increasing regulations to reduce emissions, the desire to reduce dependence on fossil fuels, and rapid gains in battery technology is creating an ideal environment for electric vehicles,” said Chris Delaney, President of Goodyear Europe, Middle East and Africa. “We are working with automakers to introduce our Electric Drive Technology next year designed to address the unique performance requirements of this growing vehicle segment.”

Automakers are looking for more durability from the tires on electrics. They're also looking to lower rolling resistance even further, in order to extend ranges and meet emissions requirements. Quieter tires are needed as well, with the nearly silent electric motors giving more prominence to other forms of noise.

Toyota claims record-setting efficiency for new engine

  Toyota claims record-setting efficiency for new engine It's part of a wider release covering all corners of the powertrain.Toyota announced a new slate of transmissions, engines and drivetrain parts for the TNGA platform. Some are focused on improved packaging, while others focus on efficiency. One engine in particular lays claim to being the most thermally efficient in its class. That seems like a good place to start.

Goodyear testing reveals that traditional tires can wear out up to 30% faster on electric vehicles due to the powerful, instant torque produced by electric motors and the With more rubber on the road, the tire can better cope with high levels of torque while maintaining high performance in wet conditions.

Goodyear claims that the new tire can combat these challenges. The new tread design uses thinner channels, so a bigger contact patch touches the The tire cavity shape is meant to support the extra vehicle weight without distorting and losing grip. And finally, the entire tire is designed with extending

So the new EfficientGrip Performance prototype with Electric Drive Technology uses a new tread design to increase durability. A network of more but thinner sipes put more rubber on the road and allow the tires to cope with the torque. The small grooves maintain traction in wet conditions. The design also helps reduce transmitted noise.

The tire's shape is optimised to handle the extra weight of electric vehicles while maintaining an optimal tread footprint. The tread compound is a new design tuned for ultra-low rolling resistance. It delivers more range but can still handle the torque. The sidewalls have been redesigned to reduce aerodynamic drag and rotating mass.

Goodyear also showed off a concept tire. One that cleans the air and has internet connectivity. The Oxygene tire is a long way from seeing the road, if ever, but it has some interesting ideas. The Oxygene tire absorbs CO2 from the air and moisture from the road. It uses them to feed moss that grows in the sidewall. Goodyear said that in a city the size of Paris, with 2.5 million vehicles, it could generate 3,000 tons of oxygen and absorb 4,000 tons of CO2 per year.

The new technology has been designed to tackle the performance necessities of the increasing EV segment. The Goodyear Tire & Rubber Company Except for the sturdiness of the tire , automakers are looking for improved rolling friction for EVs . Underdeveloped recharging infrastructure in most of

GoodYear is set to unveil a new tire that they say is optimized for EVs . The tire is designed to wear down less from the instant torque and also be EVs do create a different problem space: very heavy vehicles with lots of torque and little engine nose. It is not unreasonable to think that some dedicated

The tire is non-pneumatic, meaning that it's not filled with pressurized air. Instead, it uses a lightweight, shock absorbing construction that is 3D printed from recycled tires. It can use energy harvested from photosynthesis to power onboard sensors including a light strip. It can also use a visible light communications system to connect to vehicle-to-vehicle and vehicle-to-infrastructure data links, becoming part of the Internet of Things.

The EfficientGrip tire is expected to arrive on vehicles in Europe next year. Don't expect to see the Oxygene at your local tire store anytime soon.

2018 Jeep Wrangler Unlimited V-6 AWD AutomaticWith its rugged capability and easy access to the open air, the Jeep Wrangler has excelled for decades as the off-road totem of the brand. And to the Jeep faithful, redesigning such an icon, as has been done with the new-for-2018 JL version, will always bring concerns that modernity will dilute the charm of this cherished backwoods four-by-four. Indeed, the new JL advances the formula further than ever before, but die-hard fans of the seven-slot grille shouldn’t fret over what is the most accommodating Wrangler yet.
