For enhanced safety, the front seat shoulder belts of the Cadillac CT5 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Alfa Romeo Giulia doesn’t offer height-adjustable seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident.

This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Giulia doesn’t offer a cap-less fueling system.

The CT5’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Giulia’s standard 50 series tires. The CT5’s optional tires have a lower 35 series profile than the Giulia’s optional 40 series front tires.

The CT5’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Giulia does not have an oil pressure gauge.

The CT5 offers an optional heads-up display that projects speed, tachometer, navigation instruction, infotainment and driver assistance information readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road.

If the windows are left open on the CT5 the driver can close them all from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Giulia can only operate the windows from inside the vehicle, with the ignition on.

Keyless-Enter-n-Go standard on the Giulia doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

When the CT5 is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Giulia’s mirrors don’t automatically adjust for backing.

Optional air-conditioned seats in the CT5 keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Giulia doesn’t offer air-conditioned seats.
