Key Differences
-
The Integra has 125% more cargo space
Put simply, the Integra is far ahead here: 24.3 cu ft compared with 10.8 cu ft. Cargo figures are measured in different ways by different makers, so small gaps may not show in practice.
-
The IS 350 has 111 hp more power
The IS 350’s 311 hp leaves the Integra’s 200 hp well behind, so if this spec matters to you, the choice is easy. The IS 350’s extra output gives it more in reserve when you need to get up to speed.
-
The Integra has better fuel economy
Not a close call. The Integra lists 32 mpg and the IS 350 lists 22 mpg. That’s a substantial gap. The Integra uses less fuel on the standard combined cycle, which matters most if you drive a lot.
-
The IS 350 has 88 lb-ft more torque
Among all the differences on this page, 280 lb-ft against 192 lb-ft is one of the most meaningful, and it favors the IS 350. The IS 350’s extra torque makes it more relaxed when fully loaded or towing.
-
The Integra has better city fuel economy
The IS 350 gives up a lot on fuel economy (city): 19 mpg, compared with 29 mpg on the Integra. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.
