2008 INFINITI G Review

KBB Editors

By KBB Editors

Updated January 28, 2025

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

Whether you’re most drawn to the G37 Coupe by style, luxury, technology or performance, you aren’t likely to be disappointed. Compared to its archrival and role model, the BMW 3 Series Coupe, Infiniti’s entry offers tremendous value.

Cons

Even though it’s hard not to have fun while behind the wheel of the G37 Coupe, many of the oft-intangible nuances for which the BMW 3 Series has earned a place in automotive history remain exclusive to the BMW.

What's New?

The all-new, second-generation Infiniti G Coupe is distinguished by more curvaceous, more muscular sheetmetal, a more refined interior and increased performance spearheaded by a stiffened platform and a bigger, more sophisticated new 3.7-liter V6 engine good for 330 horsepower.

The 2008 Infiniti G37 Coupe is the follow-up to the car that put Nissan’s luxury brand on the map—in the division’s 18th model year. Rival coupes from Audi and Lexus are on the horizon, but until then the G Coupe will continue to compete in a two-car sub-category with the BMW 3 Series Coupe. While the faster, better-handling second-generation G Coupe doesn’t deliver the famously nuanced driving dynamics of the 3 Series, it’s fun, stylish and comfortable nonetheless, and enjoys a notable price advantage.

2008 INFINITI G Pricing

2008 INFINITI G pricing starts at $6,167 for the G G37 Coupe 2D, which had a starting MSRP of $34,965 when new. The range-topping 2008 G G37 Sport Coupe 2D starts at $8,866 today, originally priced from $43,415.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2008 INFINITI G models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the INFINITI G

If you’ve developed an appreciation for the subtleties in response, feedback and behavior that have traditionally distinguished performance-oriented European cars from the rest of the world’s, you’ll enjoy the 2008 Infiniti G37—just not as much as you’d enjoy the iconic BMW 335i. Regardless of your affinities, there’s a good chance that back-to-back drives would leave you questioning the BMW’s price premium that can stretch toward $10,000. Performance-focused drivers hoping for a more sophisticated, premium-badged Nissan Z will find satisfaction in the Infiniti’s 330-horsepower V6 and eager, tenacious handling. Drivers looking for a sporty looking but comfortable coupe will appreciate the refined accommodations and pleasant highway ride. We liked both the six-speed manual transmission and the sport-oriented five-speed automatic with downshift rev matching, and both steering and brake feel were similarly satisfying.

Interior Comfort

While you can’t argue with the new model’s increased performance or even sexier sheetmetal, our “most improved” vote goes to the passenger cabin. The seven-inch LCD screen included on all models radiates colorful and attractive graphics that further enhance the new model’s more contemporary vibe. We also like the visually soft aluminum alloy trim (inspired by Japanese washi paper, Infiniti says), as well as the optional African rosewood trim. Except for limited headroom, the rear seats are more accommodating than might be apparent. Sport models include a unique 14-way adjustable driver’s seat with thigh extensions and power-adjustable bolsters.

Exterior Styling

In following up the wildly successful first-generation G Coupe, Infiniti’s designers did an admirable job of delivering a design that’s both wholly familiar and decidedly fresh. Shapelier, more defined sheet metal is adorned with standard-issue High Intensity Discharge (HID) bi-xenon headlights, LED taillights, two big exhaust outlets and 18-inch wheels. Available 19-inch wheels are also included on the Sport and Sport Package-equipped models that also feature a more aggressive front fascia and side sills and an optional rear spoiler.

Favorite Features

Attractive Display
The touch-screen LCD display found in every G37 features an intuitive, visually appealing interface and serves as the control center for optional features like the best iPod integration we’ve used, a navigation system with real-time traffic info, rearview monitor, 9.3-gigabyte music hard drive and a CompactFlash card reader for music.

Intelligent Cruise Control
The G37’s available Intelligent Cruise Control system will detect a slower-moving vehicle ahead and reduce speed accordingly. It can also identify sudden braking ahead and prepare the brakes for a panic stop.

Standard Features

At base price, the Infiniti G37 Coupe includes Infiniti Intelligent Key remote-sensing unlock and start, a seven-inch LCD monitor, High Intensity Discharge (HID) bi-xenon headlights, leather seating, 18-inch wheels and a six-speaker sound system with MP3-compatible CD player, XM satellite radio and auxiliary audio input. A long list of standard safety equipment includes front, side and two-row side curtain airbags, stability and traction control and an advanced braking system.

Factory Options

The 2008 Infiniti G37 Coupe offers a long list of desirable options, highlights of which include Intelligent Cruise Control, adaptive headlights, Bluetooth hands-free cell phone connectivity, Infiniti Interface System for iPod, four-wheel active steering with variable steering ratio, comprehensive 11-speaker premium audio system and a hard drive-based, touch-screen navigation system with real-time traffic info, 9.3-gigabyte digital music storage and more. Sport models are distinguished by 19-inch wheels, a limited-slip differential, more aggressive suspension, bigger brakes, sport seats, paddle shifters (automatic only) and a sportier front fascia and side sills.

Engine & Transmission

The beating, spinning heart of the second-generation G37 Coupe is the most powerful iteration yet of the ever-evolving, world-renowned V6 that motivates several Nissan and Infiniti vehicles. In addition to a size increase, the new VQ engine incorporates variable valve control, resulting in an impressive power increase as well as an improvement in fuel economy versus both the current G35 sedan and the first-generation coupe.

3.7-liter V6
330 horsepower @ 7000 rpm
270 lb.-ft. of torque @ 5200 rpm
EPA city/highway fuel economy: 18/24 (automatic), 17/26 (manual)

2008 INFINITI G Depreciation

Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.
