"The 2020 Alpina B7 is here and it may have just beaten the Dodge Charger SRT Hellcat as the world's fastest sedan.
We don't have an official confirmation yet as the B7 just released last week and nobody has gone out on the track to test it, but according to Alpina, the B7 has a top speed of 205 mph while the Hellcat can only manage 204 mph." - Hotcars.com

"Admittedly, it isn't the fastest sedan to 60 mph. That designation is reserved for the Tesla Model S P100D. However, the 2020 ALPINA B7 now has a top speed of 205 mph, which obliterates the Model S' and even just slightly edges out the 707 hp Dodge Charger Hellcat's 204 mph.
Admittedly, it will likely take the B7 a bit longer to reach 205 mph than it takes the Hellcat to reach 204 mph, but it still wins the numbers-bragging-rights game - BMWblog.com
