The 2008 Infiniti G37 and 2007 BMW 335i coupes went head‑to‑head on Alabama’s Barber Motorsports Park, offering a rare chance to compare two rear‑wheel‑drive sports cars that share a generation but differ in engineering philosophy.
Dimensions and exterior styling set the tone
The Japanese coupe measures about 2.8 inches wider and sits lower than its German rival, which is 2.4 inches longer and 1.8 inches lower than the sedan version. Both models sacrifice rear‑seat space for sleek, fastback silhouettes that prioritize visual impact over practicality.
Cabin appointments reflect divergent heritage
Inside, the German model leans on traditional wood veneers and double‑stitched leather, while the Japanese counterpart opts for aluminum trim with a washi‑paper effect and violet ambient lighting. Headroom favors the former by roughly 0.8 inch, though the latter’s roofline tapers sharply toward the rear.
Trunk capacity also diverges: the Japanese vehicle offers 7.4 cubic feet, roughly 3.7 cubic feet less than the German coupe, limiting cargo to a few bags.
On the road, the Japanese coupe’s 4‑Wheel Active Steering (4WAS) adjusts front steering ratio and adds up to one degree of rear‑wheel steer, a feature absent in the test‑bed German version.

Both cars arrived equipped with premium and sport packages, including paddle shifters and adaptive sport‑driving algorithms that sharpen shift timing and throttle response.
During a 100‑mile drive to Fort Payne, the Japanese model proved easier to start thanks to standard keyless entry and a more intuitive Bluetooth interface. The German counterpart required a separate keyless‑entry option costing roughly $500.
On uneven freeway sections, the Japanese car delivered a firmer ride, whereas the German model cushioned bumps more effectively, providing a smoother feel for occupants.
Rain‑slicked tarmac at Little River Canyon tested each car’s stability. Both used Bridgestone Potenza RE050A tires, which gripped well. The Japanese vehicle’s stability control rarely intervened, while the German car’s torque‑converter lockup occasionally produced excess thrust, prompting more frequent DSC correction.
Engine output differences are notable: the German model’s twin‑turbo inline‑six produces 300 hp and comparable torque, while the Japanese powerplant, a stroked 3.7‑liter V‑6 with variable valve timing, offers roughly a ten‑percent horsepower edge but slightly less torque.

At Alabama International Dragway, the German car’s shorter gearing and higher torque yielded a 0‑to‑60 time of 5.1 seconds, edging the Japanese by 0.3 seconds. Quarter‑mile times mirrored this gap, with the German posting 13.7 seconds and a trap speed about 3 mph higher.
Braking performance was nearly identical; both models stopped from 60 mph within 110 feet, and lateral grip measured around 0.84 g for the German and 0.83 g for the Japanese.
Fuel consumption highlighted another contrast. Over the 400‑mile itinerary, the Japanese coupe recorded 18.4 mpg, roughly 3.3 mpg less than the German, whose lighter weight and smaller displacement contributed to better efficiency.
Pricing placed the Japanese vehicle at $47,775, about $8,000 less than the German, which carried a higher base cost despite similar equipment levels.
The modest performance gap, combined with the lower price and the absence of an oil‑cooler issue that plagued the German test car, suggests the Japanese coupe offers a compelling value proposition for buyers prioritizing cost and handling balance.
