The standard Infiniti G37 models powered by the 3.7-liter V6 deliver about 330 horsepower, a figure that applies to the coupe, sedan, and convertible in this generation. If you’re chasing more power, Infiniti’s Performance Line (IPL) variants push beyond 330 HP.
Power under the hood: the 3.7-liter VQ37VHR
The G37 uses the VQ37VHR 3.7-liter V6, a high-revving engine tuned to produce roughly 330 horsepower at about 7,000 rpm and around 270 lb-ft of torque (approximately 366 Nm). This output is largely consistent across body styles—including coupe, sedan, and convertible—and across most market trims that used the standard V6 configuration. Transmission choices varied by year and model, with manual and automatic options available depending on the specific variant.
Engine details
Key characteristics of the VQ37VHR in the G37 include its high-rev capability and streamlined intake/exhaust tuning that help achieve the 330 HP rating. While horsepower is widely cited as 330 HP for the non-performance variants, exact figures can vary slightly by market, emission controls, and transmission pairing.
Which G37 models reach 330 HP?
Below are the main G37 configurations that are typically rated at 330 HP. These enumerate the standard, non-performance versions that shared the same 3.7L V6 tune across most markets and model years.
- Infiniti G37 Coupe — 330 HP
- Infiniti G37 Sedan — 330 HP
- Infiniti G37 Convertible — 330 HP
- Infiniti G37x AWD variants — 330 HP
Note: While these variants commonly listed 330 HP, specific market calibrations or model year updates can cause minor fluctuations in peak horsepower. The IPL variants described below offer higher output.
Higher-performance options: IPL and other tuners
For enthusiasts seeking more than 330 HP, Infiniti offered the IPL (Infiniti Performance Line) G37 variants. These models featured power and handling upgrades that increased output beyond the standard rating, with typical figures in the mid-to-high 340s or near 350 HP depending on year and market. In addition to horsepower, IPL variants often included suspension, brake, and styling improvements.
- IPL G37 Coupe — roughly 345–350 HP
- IPL G37 Sedan — roughly 345–350 HP
- IPL G37 Convertible — roughly 345–350 HP
Because IPL cars were limited runs and subject to regional approvals, availability can be scarce, and exact horsepower figures can vary by production year and destination. When shopping used, verify the specific engine tuning and VIN details to confirm output.
Bottom line: Which G37 has 330 HP?
The standard G37 models built around the 3.7L V6 deliver about 330 horsepower, a figure that spans the coupe, sedan, and convertible body styles. If you see numbers notably higher than 330 HP in a G37, you’re likely looking at an IPL-tuned example or a market-specific variation. For the pure 330 HP baseline, target the non-IPL G37 configurations.
Summary
The 3.7-liter V6-powered Infiniti G37 lineup centers on a 330 HP baseline for standard versions across coupe, sedan, and convertible body styles, with IPL variants offering higher output for those seeking extra performance. When evaluating a G37, confirm the exact model year, trim, and VIN to determine the precise horsepower rating and any performance upgrades.
