US-based automaker Tesla's Model 3 has become the country's best-selling electric car, according to Bloomberg. The company delivered 8,180 Model 3 vehicles in the first quarter of 2018, as compared to 6,468 deliveries for Toyota's Prius Prime plug-in hybrid and 4,375 for General Motors's Chevy Bolt. This comes despite reports suggesting production bottlenecks of Model 3 cars.
