BMW M5 vs Mercedes-AMG E63 S - AutoAdvisor.co.za

The most eagerly awaited drag race of the year is finally here!! The new BMW M5 meets the Mercedes-AMG E63 S. Both have twin-turbo V8s. Both have all-wheel drive. But despite weighing more, and having a smaller engine, the older E63 S produces 450kw compared to the M5's 441kw. Which side of the fence are you on?
