Volvo is working on developing a new performance brand of vehicles. The brand, Polestar, has big plans to create a series of electric hybrid luxury and performance vehicles that will be completely stand-alone from Volvo. The first vehicle, the Polestar 1, will be revealed in the next couple of years as a performance two-door sedan that seats four. The Polestar 1 will be primarily an electric powered vehicle, however will also have a small internal combustion engine for extended range. The Polestar 1 will have about 600 horsepower, about 740 ft-lb of torque, and will be designed as a true driver’s car with many high-performance features and sports car styling. The 600 horsepower rating will come from a fully electric drivetrain that delivers power to the wheels with specialized torque vectoring technology that will allow the car to distribute wheel torque to individual wheels and reduce the likelihood of tire slippage during heavy acceleration. According to Polestar, the Polestar 1 will be the first car to incorporate specialized Ohlins electronically controlled suspension and the chassis will be super lightweight because it will be formed from sheets of carbon fiber.
Polestar and Volvo are taking aim at a new generation of mid-sized electric or hybrid vehicles that provide high-performance and low emissions. Other vehicles in this category are being developed by major brands, however Tesla may be the only true competitor to Polestar when the Polestar 1 comes out until other manufacturers join in the competition. Polestar is developing the Polestar 1 on scalable architecture which will allow their engineers to share similar chassis and design concepts between several different models of vehicle. Polestar has plans to eventually offer other electric hybrid vehicles in their lineup, including a sport utility vehicle dubbed the Polestar 3. Production of the Polestar 1 will commence in China in time for a mid-2019 release date.

The National Highway Traffic Safety Administration (NHTSA) is helping the automotive industry develop a new technology to help make cars safer. The technology is termed vehicle to vehicle (V2V) communications and it is being developed to provide vehicles with close-range communication abilities. Vehicle sensors have been focused on helping drivers determine where their vehicle is in relation to the surrounding environment. Rear backup cameras, vehicle sonar, lane departure warnings, and active emergency braking are all systems that assist the driver in knowing where their vehicle is in relation to other object. V2V communications is intended to enhance the abilities of current safety sensors by sending and receiving vehicle information between vehicles as they travel down the roadway. How does it work? Wireless transmitters and receivers located in each vehicle work to communicate vehicle information between the onboard vehicle and surrounding vehicles. The wireless transmitters can transmit data on vehicle speed and heading, and can also sense position of the vehicle in relation to other vehicles with the same sensor setups. The wireless signals are designed to detect and analyze vehicle information from other vehicles that are located nearby, to a proximity distance of about 300 meters. For example, a vehicle following another vehicle on the same roadway would detect information about the front vehicle’s speed or whether or not the front vehicle had begun emergency braking, providing the driver of the following vehicle with either a brake assist, or a noticeable warning as to the behavior of the front vehicle.
The National Highway Traffic Safety Administration is expecting that the V2V systems will help increase vehicle safety and reduce the number of automobile crashes, however other uses for the system could be implemented as well. For example, detection of stolen vehicles could be sensed by vehicles surrounding the stolen vehicle. Information pertaining to the vehicle’s driver could also be shared between other vehicles. V2V communication will allow more vehicle and driver data to be collected which could benefit the entire transportation industry as a whole.

Ford Motor Company is planning on developing and building a large-scale wind tunnel facility at their Allen Park building complex in Allen Park, Michigan. Building of the wind tunnel is expected to begin fairly this year, and be completed around the end of 2019. The building project will cost approximately $200 million to execute and Ford is expecting to include several advanced environmental testing environments as part of the wind tunnel. The testing environments that are part of the design of the wind tunnel include a “rolling road” system that is designed to simulate vehicle-to-roadway travel as the vehicle sits stationary in the wind tunnel. The rolling road is expected to assist in testing real-world vehicle dynamics and behavior without having to remove the vehicle from a controlled test environment. In other words, the test facility will “bring the road to the vehicle, instead of bringing the vehicle to the road”. The test facility will also include the capability to control environmental temperature during vehicle testing. The temperature will be controllable at any temperature between minus 40 degrees Fahrenheit up to 140 degrees Fahrenheit. The wind speed in the wind tunnel will also be able to simulate real-world drag testing up to over 200 mph. Ford expects that their new supercar model, the Ford GT, will require aerodynamic testing up to the limits of the new wind tunnel. Ford will use a 13-acre parcel of land, next to their existing Ford Drivability Test Facility, for the location of their new wind tunnel.
Ford is expecting new vehicle models to require advanced aerodynamic testing because of new fuel economy requirements set forth by the EPA. With new fuel economy requirements also comes improved performance and efficiency from new product lineups to allow Ford to remain a top producer of domestic automobiles in the United States.
