New H3 4 cylinder engine 

  

The H3 is a 1175cc, 16 valve L4 engine.  It is very light and compact and can better many V8 engines in turbo form.  The engine is ideally suited for track cars and other lightweight race or recreational vehicles.

The first engine is being custom configured for Henry Nicklace at Chiron Cars. Jack Frost at Holeshot racing will build the turbo engine for Chiron. 

Manufacturing will be complete in a few months.  Look for updates! 

 

 

 

 

UPDATE: MAY 2013, Assembly of the H3 has begun.  Pictures and details will be posted on the H3 page listed in the side menu.

UPDATE:  As of March 2012, the H1 and H2 engine technology has been sold.  The new owner will further develop the technology for race applications. 

Hartley Enterprises retains the rights to build these engines in limited numbers for select existing customers and special projects in the US.  All projects are taken for 2013 and no new H1 or H2 projects can be accepted at this time.
