The INFINITI Q70 lineup starts with the standard-wheelbase 3.7 and 3.7 Luxe, the straightforward V6 luxury sedans. L 3.7 and L 3.7 Luxe stretch the body for more rear-seat room, while Hybrid and Hybrid Luxe focus on fuel savings and low-load electric driving. The 5.6 and 5.6 Luxe are the standard-wheelbase V8 branch; L 5.6 and L 5.6 Luxe combine that V8 with the roomier long-wheelbase body. In these names, “L” signals the longer, rear-seat-focused version, while “Luxe” is the later name for a richer standard equipment set.
The 3.7 and 3.7 Luxe form the standard-wheelbase, V6-powered heart of the Q70 lineup, centered on quiet comfort and traditional luxury-sedan character.
Best for: Drivers who want the classic Q70 experience without the longer body, hybrid system, or V8.
The L 3.7 and L 3.7 Luxe are the roomy V6 versions, built around rear-passenger comfort rather than added engine power.
Best for: Shoppers who regularly carry adults in back and value rear-seat space more than V8 power.
Highlights
Adds a longer body, substantially more rear legroom, heated rear seats, and soft-close rear doors over the Core Model.

The L means long wheelbase. Q70L models have a stretched body with 5.6 inches more rear legroom than the regular Q70. They also emphasize back-seat comfort with features such as rear door cinchers.
LUXE is the trim name INFINITI applied to the gas-powered Q70 lineup starting in 2018. Earlier versions usually use names such as 3.7, 5.6, L 3.7, and L 5.6 without the LUXE label.
The engine is the main difference. The 3.7 uses a 330-horsepower V6, while the standard-wheelbase 5.6 uses a 420-horsepower V8. In many years, the 5.6 also came with a richer set of cabin and parking technology.
The L 3.7 keeps the same 330-horsepower V6 but uses the longer Q70L body. It adds 5.6 inches of rear legroom and rear-focused touches such as door cinchers. The regular 3.7 has the shorter body.
Both use the 5.6-liter V8, but the L 5.6 has the longer body and 5.6 inches of extra rear legroom. The regular 5.6 focuses more on the driver, while the L 5.6 combines strong power with a roomier back seat.
The Hybrid uses a 3.5-liter V6 and electric motor for 360 total horsepower, while the 3.7 has a conventional 330-horsepower V6. The Hybrid emphasizes lower fuel use and quiet electric operation under light loads.
The Hybrid pairs a V6 with an electric motor for 360 total horsepower and better fuel economy than the gas models. The 5.6 uses a naturally aspirated V8 with up to 420 horsepower and has the more traditional big-sedan power delivery.
The 3.7 or later 3.7 LUXE is the straightforward choice. It has the 330-horsepower V6 and the regular-length body. On newer examples, the LUXE also carries navigation, Bose audio, leather seating, and parking cameras.
Look at a Q70L trim. The L 3.7 centers on rear space without the V8, while the L 5.6 combines that roomy back seat with stronger power. Later LUXE versions also include heated rear seats and rear door cinchers.
The standard-wheelbase 5.6 is the engine-output leader with a 420-horsepower V8. The long-wheelbase L 5.6 uses a 416-horsepower version, while the Hybrid makes 360 horsepower and the 3.7 V6 makes 330.
On 2019 models, the 3.7 LUXE includes navigation, Bose audio, leather-appointed seats, heated and cooled front seats, a heated steering wheel, a surround-view camera, and front and rear parking sensors.
The long-wheelbase Q70L trims are the ones to check. On later L 3.7 LUXE and L 5.6 LUXE models, heated rear seats and power rear door cinchers support the car's rear-passenger focus.
No. Equipment varies by year and trim. V8 versions commonly include those features, while V6 cars gained them as standard equipment on the 2019 3.7 LUXE. Earlier V6 examples may depend on an equipment package.
No. Hybrid LUXE is the later name for the same basic hybrid member of the Q70 family. It still uses a 3.5-liter V6, an electric motor, and a 360-horsepower system; the LUXE wording reflects the later naming scheme.
