Hartge is a tuning company that specialises in tuning/modifying cars made by BMW.
The modifications range from suspension upgrades, tuning of standard engines and also engine conversions.
In 1985 Hartge were approved as a car manufacturer in their own right by the German Motor Vehicle Authority (KBA), allowing them to register a new car as a Hartge product in its own right rather than a modified BMW.
The H23 was almost the same as the modified 323i Alpina C1 2.3; Hartge took the 170 hp 2.3 liter engine and did similar modifications methods used by Alpina , a much better camshaft and cylinder head forged pistons to raise compression to 10:1.
This pristine example comes out of private collection and underwent a complete restoration a number of years ago.
She presents as new, is rare and highly collectible.
