Chevrolet's pony car has a refresh for the 2019 model with a host of changes that run more than skin deep. The front and rear have been updated for better airflow and aerodynamics, reducing drag and lift at each end. The SS model gets its own design, with a wide-open front grille and a new 10-speed, paddle-shift automatic transmission. But the biggest news might be the base model. The Turbo 1LE package has GM's 275-horsepower, 2.0-liter four and a six-speed manual, along with the track-ready suspension improvements from the V6 1LE. Pricing is yet to announced, with deliveries expected later in 2018.
