On a presentation at the Geneva Motor Show, a discussion was made about the dropping popularity of diesel engines. Cities like Paris and Stuttgart have decided to ban diesel cars. Although diesel engines were never the primary source of pollution, they were a part of smog creation. Volvo, a car maker that decided to build 4-cylinder engines, is the prime example of how smaller engines with added electrification can compensate power and still be a cleaner solution for the environment. Volvo CEO Hakan Samuelsson stated that the diesel engine production will continue. Volvo’s first electric car will be introduced in 2019.
