1946 HRG Aerodynamic

L/W98roadUnited Kingdom
Engine
1.5L inline-four (Singer unit; later replaced with 2.5L Lea Francis during ownership, subsequently restored to correct 1.5L)

The HRG L/W98 is a rare pre-war-designed British lightweight sports car imported new to Lisbon in 1947 by Norwegian-descended ship chandler Simon Knudsen Hansen, who campaigned it extensively in Portuguese motorsport between 1948 and 1951, accumulating multiple class wins in rallies and hill climbs. After the original 1.5-litre engine was replaced mid-campaign with a 2.5-litre Lea-Francis unit, the car was later discovered in Portugal in 1989 and subjected to a thorough restoration, including fitment of a correct 1,500 cc engine, to the standard it retains today.
