2008-2012 Infiniti G37X Sedan Buying Guide: AWD VQ37 Sleeper
The G37X sedan is the AWD sleeper nobody talks about — and maybe that's exactly why you should care. While everyone hunts overpriced 335i's and deals with N54 nightmares, the G37X sits quietly making 330 horsepower from a bulletproof VQ37VHR. Same engine as the 370Z, but with four doors and ATTESA AWD grip that actually works.

VQ37 Makes 330HP Stock
Infiniti underrated the VQ37VHR at 328 horsepower — dyno-proven numbers show closer to 330hp at the crank while BMW's N54 grenades turbos at 80k miles. The VQ37 is the same bulletproof motor found in the 370Z, just tuned slightly different for sedan duty. Unlike the complexity of German turbo motors, this naturally aspirated V6 runs forever with basic maintenance.
The power delivery is immediate — no turbo lag, no boost threshold nonsense. Just linear power that builds to 7,500 RPM redline. For perspective, a stock G37X traps 105-107 mph in the quarter mile, which puts it right with a stock 335i but without the maintenance headaches. If you're building for power, the VQ37 handles 400hp reliably with just intake, exhaust, and tune — check out our guide on forgotten performance sedans for more sleeper options in this price range.
Why The G37X Is Sick
ATTESA AWD hooks harder than BMW's xDrive — no more spinning through first gear like RWD G37 sedans. The system sends 100% power to the rear under normal driving, then transfers up to 50% to the front when it detects slip. It's rear-biased AWD that actually enhances the driving experience instead of dulling it.
The VQ37 is bulletproof to 400hp — just intake, exhaust, and tune for reliable power gains. Compare that to a 335i where you're looking at downpipes, intercoolers, fuel pumps, and constant worry about wastegate rattle or turbo failure. The G37X makes its power naturally and keeps making it for 200,000+ miles with basic maintenance.
Price advantage is massive: $15,000 less than a comparable 335i with half the repair bills. No turbos to fail, no high-pressure fuel pumps to replace, no carbon cleaning every 40k miles. For wheels and tires, the G37X runs 18x8 +43 front and 18x8.5 +38 rear on 5x114.3 bolt pattern — browse our 18-inch wheels in 5x114.3 for fitment options that work perfectly on this platform.
What Actually Breaks
Gallery gaskets weep oil around 100,000 miles — it's a $1,200 fix but not urgent. The leak is slow and won't strand you, just check oil levels regularly. It's the VQ37's only real weakness and it's predictable.
Steering lock actuator fails and strands you — this is the big one. The electronic steering lock can fail without warning, leaving you unable to start the car. A $400 delete kit prevents it entirely, and most enthusiasts do this modification immediately. It's cheap insurance against being stranded.
CVT in base models is trash — but X models get the 7-speed automatic which actually holds power. The 7AT is bulletproof and responds well to tuning. Manual transmission was never offered on the X model, but the 7AT is actually good enough that you won't miss it. For suspension upgrades, quality coilovers like the suspension options we carry transform the G37X's handling without compromising daily drivability.
Who It's For
You want AWD grip without German repair bills — this is the reliable choice. The G37X delivers 330hp and all-weather capability without the complexity that kills BMW ownership experience. It's for enthusiasts who understand that reliability matters more than badge prestige.
You're building for 400hp maximum — beyond that the VQ gets expensive fast. But for most street builds, 400hp from a naturally aspirated V6 with AWD is plenty. The platform responds well to basic bolt-ons and tuning without requiring internal work.
You need four doors that don't look like a cop car — flies under every radar. The G37X sedan is invisible to police and insurance companies while delivering genuine performance. It's the opposite of flashy, which is exactly the point. Check out more underrated project cars if you appreciate this stealth approach to performance.
Buying Checklist
Verify it's the X model with AWD — base G37 sedans are RWD only. Look for the "X" badge on the trunk and "ATTESA" markings under the hood. The AWD system is the whole point of choosing this over a regular G37 sedan.
Check for steering lock issues — if the car won't start or shows steering lock errors, walk away immediately. This problem will strand you and indicates the previous owner didn't address the known issue. A functioning car should start normally every time.
Service records matter — oil changes keep the VQ happy for 200,000+ miles. Look for consistent maintenance history, especially oil changes every 5,000 miles. The VQ37 is bulletproof with proper care but will develop issues if neglected. For wheel accessories once you buy, grab some 90-degree valve stems at $3.80 for easier tire pressure checks and quality center caps to complete the look.
The G37X represents everything right about Japanese performance engineering — reliable power, intelligent AWD, and honest pricing. While others chase German complexity or American excess, the G37X delivers exactly what most enthusiasts actually need.
