MERCEDES-BENZ will fast-track the all-new E63 AMG sedan for Australianshowrooms in December, priced at $234,900. As before the heart of the new E63 lies a slightly more powerful 386kW (up from 378kW) version of AMG’s 6.2-litre petrol V8, which produces the same 630Nm of peak torque and revs to 7200rpm.
