New for 1958 was the quad lamp restyle, credited to Harley Earl, but likely to be the hand of Chuck Jordan . The 1958 Corvette was 2inches wider and 9inches longer, and the rear suspension was improved, At the front the bonnet acquired horizontal louvres (nicknamed 'washboard'), but they were just decorative, as were the chrome 'suspenders' that ran down the bootlid. Four versions of the 283cu in (4,637cc) V8 engine were available from 245bhp to 290bhp injected. Carl Renner had already given the Corvette its side cove (1956), and would give its ducktail rear end (1961).
