In our first matchup, we’ll take a look at equivalent base trims equipped with all-wheel drive. When it comes to performance, the Giulia outperforms the IS 300 in both horsepower and torque. A more-sophisticated 8-speed automatic transmission also gives the Giulia better response and contributes to its superior fuel efficiency. Speaking of efficiency, the Giulia tops the IS 300 across all three MPG categories. Choosing Alfa Romeo means you’ll get more thrills on your daily drive while spending less time and money at the pump. Shifting our attention towards convenience and interior features, the Giulia continues to shine. You’ll enjoy standard rain-sensing windshield wipers for added visibility in harsh weather conditions along with standard ParkSense Rear parking sensors to take the guesswork out of parallel parking. Each of these useful features are costly options at Lexus.

The Giulia offers genuine leather seating surfaces compared to the synthetic NuLuxe Leatherette found inside the IS 300. Its rear seat also offers a 40/20/40 split folding configuration for greater cargo and passenger-carrying versatility. The interior of the Giulia also offers 5 more cubic feet than the Lexus IS 300, highlighting its generous interior dimensions.

Our second challenger to go up against the Alfa Romeo Giulia is the INFINITI Q50. As we saw in the prior comparison, the competition simply cannot compete with the performance found on the Giulia. It offers greater torque and a more advanced 8-speed automatic transmission. All this power doesn’t have to mean sacrificing on fuel economy. Across city, highway, and combined MPG ratings — the Giulia proves to be the superior choice. The Giulia also offers a turning radius which is one foot smaller than the Q50, making it easier to maneuver in or out of a tight space. When parking, standard ParkSense Rear parking sensors provides added confidence. You’ll be required to pay extra to receive parking sensors on the INFINITI.

Comparing the interiors of both of these luxury sedans also reveals a few key differences. First, the Giulia offers a greater number of speakers in its audio system for an improved listening experience. Choosing Alfa Romeo also means that you’ll receive genuine leather seats, a 40/20/40 split folding rear seat, and power 4-way lumbar support for both the driver and front passenger. All three are features that the INFINITI Q50 can’t match.

Alfa Romeo Giulia vs Mercedes-Benz C-Class

The third and final rival to take on the Alfa Romeo Giulia Ti is the Mercedes-Benz C 300 4MATIC. While the starting MSRP for both vehicles are nearly the same, comparing the performance capabilities of both reveal a noticeable difference. Driving a Giulia Ti means that you can enjoy a 25 horsepower advantage along with 33 lb feet of additional torque. Standard 18-inch alloy wheels also give the Giulia Ti a confident stance whether in-motion or at a standstill.

The proximity key on the Alfa Romeo Giulia Ti gives drivers push button start along with keyless entry doors for quick access. Mercedes-Benz only offers push button start. Standard ParkSense Rear provides peace of mind by alerting you to objects and obstacles behind your Giulia Ti. Again, this is an added-cost option on the C-Class.

Other premium amenities found inside the Alfa Romeo Giulia include heated seats, a heated steering wheel, 8-speaker sound system, and voice-activated audio controls. All three will cost you extra on the Mercedes-Benz C 300.
