US car sales analysis 2018 Q2 – Sports Mid-sized segment

Porsche Cayman soars and Chevy Camaro drops as segment decline continues

US Small Sports

Sales in the US Mid-sized Sports segment fell by 11.5% to 110,646 in the first half of 2018, as the segment’s moderate decline continued unabated, with the big three muscle cars (Ford MustangChevrolet CamaroDodge Challenger) remaining unchanged in 2018. While the second half of the year will see the release of the new BMW Z4, its relatively low volumes mean that it is unlikely to make much of a dent in this state of things.


  • The sales see-saw continued for the segment-leading Ford Mustang, with the model recovering somewhat from the 15% sales decline in the first quarter thanks to a 5% sales rise in the second quarter
  • By contrast, Mustang’s closest recent competitor, Dodge Challenger, saw its sales fall in the second quarter, allowing the Ford to re-open a lead of over 5,000 cars
  • Sales of the Chevrolet Camaro, which topped the segment between 2010 and 2014, are getting close to free-fall territory, with the decline in Q2’18 being almost 45%

  • The facelifted Porsche Cayman continued its amazing sales rise, with second quarter figures rising by a scarcely-believable 80%, enough for the high-end car to outsell the much-more-affordable Nissan 370Z in Q2’18
  • Porsche Boxster, by contrast, is having a much-worse time than its fixed-top sibling, with sales dropping by 15% in the second quarter
  • Sales of Audi TT recovered somewhat after their 41% decline in the first quarter, although that was still not enough to get ahead of the aging Mercedes-Benz SLC, meaning the once-trendy Audi is now only ahead of the Alfa Romeo 4C in the rankings
