There are many cars with a 300 mph speedometer. Basically, any performance car or sports car will have a speedometer that goes up to at least 300 mph. This doesn't even include some supercars like Pagani, Bugatti, and Koenigsegg, whose speedometers typically display up to 400 mph or more. Performance cars include the Mercedes-AMG series, BMW M series, Audi RS series, Volkswagen R series, and more. Additional Information: 1. Some high-end models also feature a 300 mph speedometer, such as the Audi A4L, A6L, A7, and A8L. However, due to electronic speed limiters, it's difficult to actually reach 300 mph. The Audi A6, A7, and A8 also have a 300 mph speedometer. The base A6 1.8T model, with a 190-horsepower L4 engine, has a top speed of 235 mph—far below the 300 mph displayed. In terms of power, it uses a 2.0T engine with a maximum output of 190 horsepower and a peak torque of 320 Nm, paired with a 7-speed AT transmission. There's also a 3.0T V6 engine and a hybrid version available, with the latter delivering up to 340 horsepower and a maximum torque of 500 Nm, offering explosive performance. 2. The new CT6 has a speedometer that displays either 300 mph or 280 mph, depending on the variant. The older models had a maximum torque of 400 Nm, but the torque plateau was in the less commonly used 3000-4300 rpm range. The newer models, while having a reduced maximum torque of 350 Nm, offer a much earlier torque plateau, delivering peak torque between 1500-4000 rpm—a more practical range for everyday driving.
