2008 Infiniti G35 Coupe Specs | The Coupe Was The G37

No, the 2008 G35 Coupe does not exist — production ended in 2007 and the 2008 coupe is the G37 with a 3.7-liter V6 making 330 horsepower.

If you searched for 2008 Infiniti G35 Coupe specs, you ran into the most persistent mix-up in Infiniti’s history. The G35 Coupe was a hit from 2003 through 2007, but for 2008 Infiniti gave the coupe a bigger engine and a new name — the G37. The G35 badge lived on only for the sedan. Here is what Infiniti actually built for 2008 and how to avoid the confusion when shopping used.

What Happened To The G35 Coupe?

Infiniti built the G35 Coupe from 2003 through 2007 using a 3.5-liter V6 rated at 280 horsepower. For 2008, the coupe received a larger 3.7-liter V6 and the G37 badge, while the sedan kept the G35 name with an upgraded VQ35HR engine making 306 horsepower. Infiniti’s official archives list the G35 Coupe as a 2003–2007 model, confirming no 2008 G35 Coupe was ever produced.

The change allowed Infiniti to differentiate the coupe from the sedan and compete with the BMW 3 Series coupe. The G37’s 3.7-liter VQ37VHR introduced Variable Valve Event and Lift (VVEL) technology for higher rpm and better throttle response. The result is a 50-horsepower jump — from 280 hp in the 2007 G35 Coupe to 330 hp in the 2008 G37 Coupe. Because the G35 name was so widely recognized, many used listings still label 2008 coupes as “G35” out of habit. Three quick checks settle it:

• Rear badge: “G37” means a 2008 or later coupe; “G35” means 2007 or older coupe or 2008 sedan.
• VIN: The 10th character tells the year — 8 means 2008.
• Engine bay: The 3.7-liter cover is visibly different from the 3.5-liter unit.

If the car is a coupe and it is a 2008, it is a G37, not a G35.

2008 Infiniti G35 Sedan Specs

The only G35 sold for 2008 was the Sedan, available in rear-wheel drive and all-wheel drive (G35x). It uses the VQ35HR engine, a refined version of the 3.5-liter V6 addressing earlier oil-consumption issues. Transmission choices are a 5-speed automatic or 6-speed manual.

Trim levels included base G35, G35 Journey, G35 Sport, and G35x, as confirmed by Infiniti’s official 2008 G Sedan press release. The Sport 6MT added a unique front fascia, side sills, and 18-inch wheels with staggered tires. All 2008 G35 sedans use regular unleaded gasoline and seat five passengers.

2008 Infiniti G37 Coupe Specs — The Actual 2008 Coupe

The coupe in Infiniti’s 2008 lineup is the G37, bringing a genuine performance upgrade. The 3.7-liter VQ37VHR delivers 330 horsepower at 7,000 rpm with a 7,500-rpm redline and 270 lb-ft of torque at 5,200 rpm. VVEL technology gives it a broader powerband — it pulls harder through the midrange and revs more freely. Transmission choices were a 5-speed automatic or 6-speed manual, both sending power to the rear wheels only. There is no all-wheel-drive option on the coupe. Fuel economy ranges from 17 city / 26 highway with the manual to 18 city / 24 with the automatic. Top speed is electronically limited to 155 mph.

Three trims were offered: Base, Journey, and Sport 6MT. The Sport 6MT added 19-inch wheels with wider rear tires, a unique front fascia, sport side sills, and firmer suspension tuning.

Quick summary: if it is a 2008 Infiniti coupe, it is a G37. The rear badge says “G37.” The engine cover reads 3.7-liter. The G35 name on a 2008 car means a sedan, not a coupe.

FAQs

Can you swap G37 parts onto a G35?

Some suspension and brake calipers interchange, but the engines are fundamentally different — the VQ37VHR has a different block, cylinder head, timing chain setup, and intake system than the VQ35DE or VQ35HR. Verify compatibility by model year and VIN before ordering parts.

Is the 2008 G37 more reliable than the 2007 G35?

Both the VQ35HR (2007–2008 G35 Sedan) and VQ37VHR (2008+ G37) are regarded as reliable when maintained on schedule. The VQ37VHR uses a timing chain rather than a belt, but some early examples had gallery gasket issues requiring attention. Check service records regardless of which car you choose.

Why do used listings still say “G35” for 2008 coupes?

The G35 name was so familiar that many listings沿用 the label out of habit. A 2008 coupe advertised as “G35” is almost always a G37 — confirm by requesting a photo of the rear badge or engine bay.
