2013 Infiniti G25 / G37 (2024)

FAQs

Are the G37 and G25 the same? ›

In comparing the INFINITI G25 Sedan's and the INFINITI G37 Sedan's specifications and ratings, the INFINITI G25 Sedan has the advantage in the areas of typical lower range of pricing for one- to five-year-old used cars, and fuel efficiency. The INFINITI G37 Sedan has the advantage in the area of base engine power.

As with all other vehicles, if you follow regular maintenance schedules and take good care of your Infiniti G37, it can last you 200,000 miles and beyond.

The 2013 G37 has a reliability score of 4.5 out of five from J.D. Power. That's among the best scores in the entire industry.

But besides that, I've learned Infiniti's are great cars and can go over 200K miles if you maintain it well. Rating breakdown (out of 5): Comfort 5.0. Interior 5.0.

Fuel economy differences between the AWD and front-drive versions were slight; the former model being a touch thirstier on the highway. Both, however, were significantly thriftier than the G37. But the G25 apparently wasn't thrifty – or sporty – enough. Infiniti quietly dropped it from its lineup in 2013.

Though power is adequate for most tasks, the G25 never feels particularly fast. In our tests, the rear-drive G25 Journey model scooted to 60 mph in 7.6 seconds. Not terribly fast, but also not slow by any means. The only transmission available is a seven-speed automatic that can automatically rev-match downshifts.

Some dealers recommended that you stay away from used cars with over 100,000 miles on them, but this certainly isn't a concrete rule. In fact, if a car is well-maintained and has been regularly serviced, it can last for well over 100,000 miles with no issues.

The annual maintenance cost of an INFINITI G37 is $540. Repair and maintenance costs vary depending on age, mileage, location and shop.

If you don't routinely and consistently change your fluids at least every 30,000 miles or so, you may find that your INFINITI G37 transmission will swiftly slip. Check your car's owner's manual for more advice on the specific mileage intervals in which your transmission needs the fluid changed.

How many miles can a G37 go on a full tank? ›

I can say with absolute certainty that the G37 goes faster than 155 mph. No aftermarket or performance parts installed, 100% factory stock. On Interstate HWY 10 between Phoenix and Tuscan; got up to 158 mph and would have gone faster if not for a strong gust of wind that got under the car.

The average total annual cost for repairs and maintenance on a INFINITI G25 is $533, compared to an average of $739 for luxury midsize cars and $652 for all vehicle models. The average total annual cost for unscheduled repairs and maintenance across all model years of a vehicle.

If you select a quality model, the average Infiniti will last about 200,000 miles. They can last more if you take proper care of the vehicle. Infiniti has a quality lifespan, especially for a luxury brand.

RepairPal gave the Infiniti G25 an overall reliability rating of 4 out of 5 stars, which RepairPal describes as Excellent. This rating ranks Infiniti G25 12th out of 68 among Luxury Midsize Cars.

Under the hood of the G25 is a 2.5-liter V6 engine, built with the same VQ engine architecture as the 3.7-liter V6 used in the G37.

The main changes are that the G35x has a 5-speed automatic transmission, compared to the revised 7-speed automatic in the G37x. When putting the transmissions head-to-head, this seems to come down to personal preference. The 7-speed has shorter gearing than the 5-speed, which in turn provides slightly improved MPG.

An Infiniti G37 by another name would be the Skyline coupe.
