Chevy Suburban vs Jeep Grand Wagoneer L: 2027 Suburban vs 2027 Grand Wagoneer L Compared
Last updated: October 18, 2026 | Emich Chevrolet, Lakewood | Specs from each manufacturer
The Chevy Suburban and Jeep Grand Wagoneer L are extended-length full-size SUVs with room behind a real third row. The Grand Wagoneer L now carries on what the Wagoneer used to be. Here is the 2027 Suburban against the 2027 Grand Wagoneer L, using each manufacturer’s published specs.
Quick Verdict
The 2027 Suburban starts $3,500 lower ($64,500 vs $68,000), seats up to nine and has a bigger 17.7-inch touchscreen, and from the LT up it offers a Duramax diesel rated at 23 mpg combined vs the Grand Wagoneer L’s 19 and Super Cruise hands-free driving, which Jeep does not. The 2027 Grand Wagoneer L has more standard power (a 420-hp twin-turbo six vs the Suburban’s 355-hp V8), slightly more cargo space behind the third row (42.6 vs 41.5 cu ft) and a higher maximum tow rating when properly equipped (9,860 lbs for the L 4×4 on Jeep’s 2026 spec sheet vs the Suburban’s 8,000 in 4WD and 8,200 in 2WD).

The Matchup: V8s and Diesel vs Twin-Turbo Six
Jeep has folded the former Wagoneer into the Grand Wagoneer line, and the 2027 Grand Wagoneer L is its extended-length version. Both SUVs are 2027 models on sale now. Jeep has not posted a 2027 spec sheet, so the L’s towing figures below come from its 2026 sheet.
Every Grand Wagoneer L uses a 3.0L Hurricane twin-turbo inline-six (420 hp, 468 lb-ft) with an 8-speed automatic. The Suburban offers a 355-hp 5.3L V8, a 420-hp 6.2L V8 and a 305-hp, 495-lb-ft 3.0L Duramax diesel, all with a 10-speed automatic.
The Grand Wagoneer L is 1.8 inches longer (228.1 vs 226.3 in.) and has a little more cargo space behind the third row (42.6 vs 41.5 cu ft). Jeep does not publish the L’s cargo space behind the second or first row; the Suburban holds 93.8 and 144.5 cu ft. Third-row legroom is nearly identical (36.7 vs 36.6 in.).
