More Extended-Range EVs Soon to Hit the Road

Renault and Volkswagen are collaborating with Chinese firms to introduce Extended-Range Electric Vehicles (EREVs) that combine EV batteries with gas-powered generators to address range anxiety. EREVs use a small internal combustion engine to generate electricity for the battery, offering high-range capability without the need for large batteries. Renault's RGEV medium 2.0 platform and VW's ID. Era 9X SUV with range-extending gasoline engine are part of this initiative, aiming to enhance electric mobility markets globally. These EREVs are expected to hit the market by 2028-2030, with up to 15 models anticipated in the U.S. by 2028.

Curved Video Screen to Replace Conventional Auto Windshield — and More

A proposal suggests replacing traditional auto windshields with large curved video screens that can display various views simultaneously, including front, side, and rear perspectives. The technology aims to enhance safety and usability while leveraging the decreasing costs of large curved screens. The video screen can dynamically adjust to show different views and data, potentially benefiting autonomous vehicles by creating a private zone for passengers and displaying essential vehicle information. Safety features include reverting to transparent mode in case of electronic failure and emergency options for screen removal. The concept raises questions about user acceptance, technical feasibility, and cost-effectiveness, but it holds potential for future automotive design.
