The 2017 GT development program has begun testing in southeastern Michigan, with the exotic American supercars running “naked” as they rack up miles amid daily commuter traffic. Automotive Engineering encountered and photographed one of the off-tool prototypes recently.
The company has put its first complete touch display with haptic feedback into demonstrator vehicles as a prelude to production. The unit is a touch-sensitive 8-in flat screen with an integrated haptic actuator system.
Metal laser melting has made a successful leap from rapid prototyping to an approved manufacturing technology, and the method is increasingly becoming an option for companies in high-tech industries, according to Toolcraft. And now the German manufacturer has teamed with Airbus APWorks to offer another option for additive manufacturing—the Airbus subsidiary’s Scalmalloy high-performance aluminum powder.
An optional five-speed transmission includes the Case Powerinch feature that lets operators approach targets quickly and precisely regardless of engine speed, ensuring there is no rollback even on steep slopes, making it easier and quicker to dump into a truck.
The challenges for the off-highway industrial engine supplier goes beyond simply meeting ever more stringent emissions regulations in Europe. Their engine designs also need to minimize total cost of ownership while delivering power and fuel efficiency in a worldwide market.
The sealing specialist is currently developing two new materials that reportedly will help aircraft manufacturers save weight and production costs while exceeding fire resistance and fireproof requirements for the engine application.
A second coolant loop in a Fiat Grande Punto prototype provides liquid cooling of the A/C condenser and turbo intercooler, with potential for including air coolers for engine and transmission oil, power steering fluid and other heat exchangers. Engineers measured a 5% improvement in fuel economy during A/C-on operation during NEDC testing.
Kohler Engines has launched the KDI 3404, a 3.4-L engine in a compact footprint with a power density of 30 kW/L that reaches 100 kW (134 hp) and features an innovative Stage V ready aftertreatment system.
