My First Impressions of the G37x and Q50
When I first slid into the driver’s seat of a 2011 Infiniti G37x, it felt like slipping into a tailored suit. The cabin was snug, sporty, and screamed “driver’s car.” Fast forward to test-driving a 2015 Q50, and I was struck by how much more refined it felt—like Infiniti had polished the edges while adding a techy vibe. Both cars share a lineage, but they cater to slightly different souls. The G37x is the raw, spirited cousin, while the Q50 feels like it’s ready for a boardroom meeting after a track day.
Performance: Power and Handling That Define the Drive
Infiniti G37x: Raw and Responsive
The G37x’s 3.7-liter V6 engine is a beast, pumping out 328 to 330 horsepower depending on the model year. I remember flooring it on an open highway and feeling that instant surge, the kind that pins you back with a grin.
The naturally aspirated V6 delivers smooth, predictable power with no turbo lag, and the exhaust note?
Pure music, especially when you push it past 4,000 RPM. The 7-speed automatic transmission shifts crisply, though I wished for a manual option on those twisty backroads.
Handling is where the G37x shines. Its hydraulic steering feels alive, giving you feedback like a conversation with the road. The all-wheel-drive system keeps things planted, even in slick conditions, but I noticed it’s not as playful as rear-wheel-drive counterparts. The sport package, with its bigger brakes and tighter suspension, makes it feel like a true sports sedan, though the ride can be stiff on rough pavement.
Pros of G37x Performance
- Potent 3.7L V6 with 328-330 hp
- Responsive hydraulic steering
- Strong AWD grip
- Satisfying exhaust note
Cons of G37x Performance
- No manual transmission option
- Firm ride with sport package
- Limited tuning potential (naturally aspirated)
Infiniti Q50: Modern Muscle with a Tech Twist
The Q50, depending on the model, offers two engines: the early 3.7L V6 (same as the G37x) or the newer 3.0-liter twin-turbo V6 with 300 hp in base trims or 400 hp in Red Sport models.
My test drive in a 2016 Q50 3.0t was a revelation—quicker off the line than the G37x, with a 0-60 mph sprint in about 4.5 seconds for the turbo version.
The twin-turbo setup delivers a punchy low-end torque, but I missed the G37x’s raw vocal character.
The Q50’s Direct Adaptive Steering (steer-by-wire) was a mixed bag. It’s light at low speeds and firms up as you accelerate, but it feels numb compared to the G37x’s tactile setup. Some owners love the customizable steering modes, but I found myself craving the old-school feedback. The AWD option is solid, though the open differential in non-sport models can lead to wheel spin in aggressive driving, as I learned during a rainy test drive.
Pros of Q50 Performance
- Twin-turbo V6 option (300-400 hp)
- Faster 0-60 times (especially 3.0t)
- Customizable driving modes
- Smoother ride in non-sport trims
Cons of Q50 Performance
- Numb steer-by-wire system
- Open differential issues in RWD models
- Less engaging exhaust note
Fuel Economy: Balancing Power and Efficiency
The G37x isn’t exactly a fuel sipper, averaging 19 mpg city and 27 mpg highway (22 combined). I noticed this during a week-long test when my wallet felt the sting of premium gas. The Q50, with its 3.0L twin-turbo, does better at 20 mpg city and 29 mpg highway (23 combined), thanks to weight reduction and better aerodynamics. On a road trip, the Q50’s 580-mile highway range gave me more peace of mind compared to the G37x’s 540 miles. Still, both require premium unleaded, so budget accordingly.

Interior: Comfort Meets Technology
Infiniti G37x: A Driver’s Cockpit
The G37x’s interior feels like a sports car’s cockpit—cozy and driver-focused. The leather seats are supportive, and the analog gauges give it a classic vibe. But let’s be honest: the infotainment system feels dated. The optional navigation screen is small, and the interface is clunky compared to modern standards. Cargo space is decent at 13.5 cubic feet, but the trunk’s narrow opening can be a hassle. I loved the Infiniti clock on the dash, though—it’s a quirky touch that adds character.
Pros of G37x Interior
- Sporty, driver-centric design
- High-quality leather (standard)
- Comfortable front seats
- Unique analog clock
Cons of G37x Interior
- Outdated infotainment
- Limited rear legroom
- Narrow trunk opening
Infiniti Q50: Modern Luxury
The Q50’s cabin is a step up in luxury. Dual LCD screens dominate the dash, offering a tech-savvy feel. The interface is more intuitive, though early models had laggy response times (fixed post-2016).
There’s more passenger space—104-113 cubic feet versus the G37x’s 99—making it better for families. The seats are plush, and options like real leather and Bose audio elevate the experience. However, I found the climate controls awkwardly placed, and the lack of a standard spare tire annoyed me.
Pros of Q50 Interior
- Spacious cabin
- Modern dual-screen infotainment
- Premium materials (especially in higher trims)
- Quiet ride
Cons of Q50 Interior
- Laggy infotainment (pre-2016)
- No standard spare tire
- Less sporty feel
Technology: Old School vs. New School
The G37x’s tech feels like a time capsule. Bluetooth and a basic touchscreen are standard, but there’s no Apple CarPlay or Android Auto. The optional navigation system is functional but low-resolution. Safety features include dual front airbags and side curtains, but advanced driver aids are absent.
The Q50, by contrast, is loaded with tech. Adaptive cruise control, lane-keeping assist, and Direct Adaptive Steering come in higher trims. The dual-screen setup integrates navigation and apps seamlessly, though I found the menus overwhelming at first. Post-2016 models boot up faster, addressing early complaints about slow infotainment.
Reliability and Maintenance: What to Expect
The G37x has a stellar reputation for reliability. J.D. Power rates it above average, and owners on forums like MyG37 praise its durability. Maintenance is straightforward, with the naturally aspirated V6 being less complex than turbo engines. However, AWD components like the driveshaft add to costs.
The Q50’s reliability is average, per J.D. Power. The twin-turbo V6 requires more maintenance due to its complexity—think cooling hoses and intercoolers. I heard from a mechanic friend that Q50s can be pricier to repair, especially if you go to an Infiniti dealer. Still, post-2016 models improved significantly.
Pricing and Value: Bang for Your Buck
A used 2013 G37x ranges from $7,945 to $17,997, making it a steal for a performance sedan. Its lower price and proven reliability make it a value king. The Q50, with used 2024 models priced between $35,980 and $48,569, is pricier but offers modern tech and efficiency. If budget is tight, the G37x wins; if you want cutting-edge features, the Q50 justifies the cost.
Driving Experience: Soul vs. Sophistication
The G37x is a driver’s car through and through. Its steering feedback and raw power make every drive feel alive.
I’ll never forget weaving through mountain roads, feeling every curve. But it’s not perfect—the firm ride and dated tech can wear on long trips.
The Q50, meanwhile, balances performance and comfort. It’s smoother on highways, and the turbo engine’s torque is addictive. Yet, the numb steering and less engaging exhaust left me wanting more soul. It’s like choosing between a rock concert (G37x) and a symphony (Q50).
