Combined with a full rear bench giving five seats (rather than a 2+2 layout) the GT was advertised as being a practical sports car.

In October 2006, Alfa Romeo introduced a 1.9 JTD Q2 version with a limited-slip differential, and also added a new trim level called Black Line.

[9] In 2008, the cloverleaf model was launched as a limited edition complete with new trim levels, lowered suspension, body kit, 18 inch alloy wheels and was only available in Black, Alfa Red, or Blue colours.

Standard features included power steering, a trip computer, air conditioning, dual climate control, airbags (including 'curtain' airbags) with internal passenger sensors to decide remotely which airbags to deploy, side mirror defrosters, and cruise control, plus options like reverse assist, seat warmers, leather interior, ten CD changer, satellite radio controls and windscreen sensors for automatic wiper activation.

Other features included VDC (Vehicle Dynamic Control) or Alfa's version of ESP (Electronic Stability Program), ASR (Anti Slip Regulation) or traction control, EBD (Electronic Brake Distribution), ABS, brake assist and later the Q2 System.

The Q2 system is Alfa's limited-slip differential technology, for improved cornering, reducing wheel spin, and torque steer, to help mitigate understeer common to front-wheel-drive cars.

[22] The "100th anniversary limited edition" version [23] is intended for the Australian and South African markets;,[24] and coloured Rosso Alfa, Atlantic Blue, Black and Ice White.

[7] The car was a four-seat open-top version of the GT coupé, which Bertone hoped to get built at their own plant.

The next-generation Alfa Romeo open-top car was instead built by Pininfarina, using the Brera coupé as a base.
