TL;DR
The Morgan Supersport has been altered to comply with US vehicle regulations by removing two cylinders from its engine. This change enables the model to be sold and registered in the US. The modification marks a significant shift for the classic sports car, but details about the process and implications remain limited.
The Morgan Supersport has been modified to meet US vehicle regulations by removing two cylinders from its engine, making it eligible for sale and registration in the United States, the company confirmed today. This change marks a significant development for the historic British marque, which has traditionally sold cars primarily in Europe.
Morgan Motor Company announced that it has re-engineered the Supersport model to be US-compliant by removing two cylinders from its original six-cylinder engine, reducing it to a four-cylinder configuration. This adjustment was necessary to meet US emissions and safety standards, which often restrict modifications involving larger engines or certain performance features. The company stated that this change was implemented in collaboration with regulatory authorities and was aimed at expanding its market presence in the United States. The modified Supersport retains its core design and performance characteristics, aside from the engine change, and is now listed as US-legal on Morgan’s official website.While Morgan did not specify the technical details of the engine modification, sources close to the manufacturer indicated that the change involved replacing the original engine with a smaller, emissions-compliant unit sourced from a different supplier. The company emphasized that this move was driven by a desire to preserve the model’s heritage while complying with US regulations, which vary significantly from European standards.
Industry experts note that such modifications are relatively uncommon for high-end sports cars, which typically rely on complex engineering to meet regulations without altering core performance features. Morgan’s approach appears to be a pragmatic solution to access the lucrative US market without developing an entirely new model.
Implications of Engine Reduction for Classic Sports Cars
This development is significant because it demonstrates how traditional manufacturers like Morgan are adapting their models to meet regulatory standards in different markets. Removing two cylinders from the Supersport’s engine could impact its performance, sound, and character, which are key selling points for enthusiasts. However, it also opens the door for more classic or niche models to be sold in the US, where strict regulations often limit such vehicles. The move signals a potential shift in how heritage brands approach compliance and market expansion, balancing authenticity with legal requirements.

Regulatory Challenges for Classic and Niche Vehicles in the US
Historically, many European sports and luxury cars have faced hurdles when entering the US market due to emissions, safety, and modification restrictions. The US Environmental Protection Agency (EPA) and Department of Transportation (DOT) impose strict standards that often require significant engineering changes. For brands like Morgan, which emphasize handcrafted, bespoke vehicles, compliance can be particularly complex. The recent modification of the Supersport reflects broader industry trends where manufacturers seek to adapt existing models to meet these standards without entirely redesigning their vehicles.
Prior to this, Morgan’s models were primarily sold in Europe, where regulations are less restrictive regarding engine configurations. The company’s decision to alter the Supersport indicates a strategic move to access the US market, which remains one of the largest for luxury and specialty vehicles.
“We have made a strategic decision to modify the Supersport to meet US standards, which involved removing two cylinders to ensure compliance. Our goal is to bring this iconic model to American customers while respecting regulatory requirements.”
— Morgan Motor Company spokesperson
Details on Engine Specification and Performance Impact
It is not yet clear exactly which engine model replaces the original, nor how the performance, sound, or driving dynamics of the Supersport have been affected by the removal of two cylinders. Morgan has not released detailed technical specifications or performance data post-modification.Next Steps for Morgan and US Market Expansion
Following this modification, Morgan plans to begin selling the US-legal Supersport through its official US dealerships. The company may also explore further modifications or new models tailored to American regulations. Industry observers will watch to see how the vehicle performs in the US market and whether similar approaches are adopted for other models or brands seeking entry into the US.
