SR20
Original version produced from 1999.

SR20 G2
Improved variant introduced in 2004, including Avidyne Entegra avionics.

SRV
Introduced at the 2003 EAA AirVenture Convention and brought to market in 2004, the Cirrus SRV was a VFR-only version of the SR20 for the low-end private ownership and flight training market.
As such it omitted some standard equipment available on the SR20 such as wheel fairings.
For 2008 the SRV model was updated to G3 configuration, with the SR22 wing.
Cirrus discontinued the SRV for the 2010 model year.

SR20 G3
Introduced in 2007, the "Generation 3" G3 has a lighter wing of greater area, incorporating a carbon-fiber spar.
The new wing increased the SR20's cruise speed by 6–7 knots (11–13 km/h).
The G3 also added a 50 pounds (23 kg) increased useful load by increasing the take-off weight to 3,050 pounds (1,380 kg), a re-designed main landing gear that is 2 inches (5 cm) taller, giving greater propeller and tail clearance, improved aircraft handling due to increased dihedral, improved aerodynamics including new wing root fairings, LED recognition lights, improved heat and ventilation, dual-redundant GPS WAAS-certified Garmin GNS 430W comm-navigators (that include a VHF radio and a VOR/LOC/ILS receiver) and an S-Tec Autopilot.

T-53A
In 2011, the SR20 was selected for cadet flight training with the 306th Flying Training Group at the United States Air Force Academy and given an Air Force model/design/series (MDS) designation as the T-53A. Twenty-five examples will be purchased to replace the Academy's current stock of 20 leased T-52As by May 2012.

SR20 G6
Introduced in January 2017, the G6 model adds a Lycoming IO-390 engine of 215 hp (160 kW), an enhanced "Cirrus Perspective-Plus" flight deck (by Garmin) with a 10-times faster instrument processing speed, new LED wingtip lights and a useful load increase of 150 lb (68 kg).

TRAC
Introduced in September 2019, the TRAC is a flight-training version with a simplified, more durable interior, IO-390 engine, Perspective+ flight deck, rear seat push-to-talk functionality, and simulated landing gear controls.
