Infinitisports cars include a short, well-defined lineup of performance-oriented sedans and coupes such as the G35 Sport, G37 Sport, IPL models, and the Red Sport 400 versions of the Q50 and Q60. Many of these remain worth buying today because they pair strong engines, rear-wheel-drive platforms, and reasonable ownership costs with used prices that make them severely underrated. This list shows the best Infiniti sports cars of all time, ranked by used price, from the most affordable to the most expensive, using current market values.This guide focuses strictly on sports sedans and coupes with performance-oriented powertrains. It is built for buyers comparing real options, and enthusiasts tracking Infiniti’s performance history. Each entry explains why the model qualifies, where it fits in the market, and what it delivers. Infiniti G35 Sport Average Used Price: $11,461 Via: InfinitiThe Infiniti G35 Sport is the most accessible entry point into the Japanese brand's sports cars. Compared to the base G35, the Sport trim adds firmer suspension tuning, larger brakes, and wider wheels, which noticeably tighten body control. Power comes from the 3.5-liter V6, producing up to 306 hp and 268 lb-ft of torque in later models. That output gives the G35 Sport a 0 to 60 mph time in the mid-five-second range, depending on transmission.Via: InfinitiRear-wheel drive is standard, built on the Nissan FM platform, which places the engine behind the front axle for improved balance. A 6-speed manual was available and remains the configuration enthusiasts seek out. In the used market, classic.com suggests the G35 Sport has a market value of around $11,461. Long-term ownership benefits from the durability of the VQ35HR, which has a strong reputation for reliability when properly maintained. However, Repair Pal states that the G35 costs $476 a year to repair and maintain, but also recorded 264 complaints with failing crankshaft angle sensor, that led to a recall which must be noted. Against cars like the BMW 330i, the G35 Sport delivers more straight-line performance for less money, with fewer long-term maintenance surprises, making it one of the most popular Infinitis money can buy. Infiniti G37 Sport Average Used Price: $12,975 Via: InfinitiThe Infiniti G37 Sport represents the peak of Infiniti’s naturally aspirated performance era. It upgrades the G35 formula with the VQ37VHR, a 3.7-liter V6 producing 330 hp and 269 lb-ft of torque. That increase translates into a 0 to 60 mph time of about 5.0 seconds with the manual transmission, putting the G37 Sport firmly in modern sports car territory even today.Via: InfinitiFor $12,975 today, G37 Sport models offer larger brakes, stiffer dampers, and available limited-slip differentials, which improve traction and consistency during aggressive driving. Buyers could choose between a 6-speed manual or a 7-speed automatic, with the manual offering better throttle response and driver engagement. The G37 Sport was sold as both a sedan and a coupe, widening its appeal within the Infiniti G-series lineup. G37 owners generally spend $540 on repairs and maintenance, while several owners reported harsh downshifts from fourth to fifth with the automatic transmission. Compared to rivals like the Lexus IS 350 F Sport, the G37 Sport offers more power and a more performance-focused chassis at similar used prices. Infiniti M56S Average Used Price: $17,750 Via: Bring a trailerThe Infiniti M56S is the outlier among this list of fast Infiniti models, combining full-size sedan proportions with genuine V8 performance. Power comes from the VK56VD, which produces 420 hp and 417 lb-ft of torque. That output pushes the M56S from 0 to 60 mph in under five seconds, rivaling many dedicated performance sedans from the same era, at a fraction of the price today in the used market at $17,750.Via: Bring a TrailerRear-wheel drive is standard, reinforcing its performance credentials despite the car’s size and weight. A 7-speed automatic is the only transmission offered, but the engine’s torque delivery minimizes the downside of skipping a manual option. M56 owners have also reported similar issues with the automatic transmission, but they spend $540 as well on repairs and maintenance per year. In straight-line acceleration, the M56S runs close to a BMW 550i, often at a significantly lower purchase price. Fuel economy and running costs are higher than V6 Infiniti models, but buyers gain refinement, power, and rarity within the Infiniti M platform. Infiniti IPL G37 Average Used Price: $23,000 Via: InfinitiAt $23,000 used, the Infiniti IPL G37 is the most enthusiast-focused version of the G-series, developed under the Infiniti Performance Line. Power comes from the same 3.7-liter V6 as the standard G37, but output rises to 348 hp and 276 lb-ft of torque. That increase, combined with revised suspension tuning, gives the IPL a 0–60 mph time in the low five-second range.Via: InfinitiThe IPL G37 was offered exclusively as a coupe, which reinforces its positioning as a performance-first model. Infiniti revised the exhaust system for higher flow and a more aggressive sound profile, while suspension changes sharpen turn-in and reduce body roll. Manual and automatic transmissions were both available, with the manual remaining the more desirable choice, especially with the jerky fourth to third issue reported with the automatic. Compared to the BMW 335i, the IPL trades turbocharged torque for linear power delivery and long-term mechanical simplicity. Limited production numbers also give the IPL G37 stronger collector interest than standard Sport trims. Infiniti Q50 Red Sport 400 Average Used Price: $23,000 Via: InfinitiThe Q50 Red Sport 400 marks Infiniti’s shift into modern turbocharged performance. Power comes from the VR30DDTT that powers the Nissan Z, producing 400 hp and 350 lb-ft of torque from just 3.0 liters. In real-world testing, the rear-wheel-drive sedan ran 0 to 60 mph in the mid-four-second range. It's more powerful, and valued at $23,000 in the used market, also cheaper than a BMW 340i.Via: InfinitiAWD availability is a key advantage at this price point, especially for buyers in colder climates. Power delivery is strong across the rev range, and the 7-speed automatic keeps the engine in its torque band without constant intervention. Post-refresh models of the Q50 addressed early reliability concerns with revised turbo hardware and cooling, improving long-term dependability. On average, the Q50 requires $648 annually for repairs and maintenance, according to Repair Pal, while no widespread recurring issues have been recorded. As a daily driver, the Q50 balances performance with ride comfort and interior space better than many rivals. Against cars like the Mercedes-AMG C43 and the Cadillac CT4-V Blackwing, the Q50 Red Sport 400 delivers similar straight-line speed for noticeably less money, making it the perfect twin-turbo sedan to buy if you can't afford a Cadillac. Infiniti Q60 IPL Average Used Price: $32,750 Via: InfinitiThe Infiniti Q60 IPL serves as a bridge between the G37 IPL and the turbocharged Red Sport era. Mechanically, it carries over much of what made the G37 IPL appealing, including the naturally aspirated 3.7-liter V6 and a focus on chassis tuning rather than outright power increases. Output remains 348 hp and 276 lb-ft of torque, which translates to a 0–60 mph time in the low five-second range.Via: InfinitiThe Q60 IPL was the last naturally aspirated Q60 model, and one of the final IPL-branded cars Infiniti produced. Suspension tuning is firmer than standard Q60 trims, prioritizing body control and steering response. The IPL program ended as Infiniti shifted toward turbocharged engines and simplified its performance strategy, leaving the Q60 IPL as a short-lived offering. A Q60 on average requires owners to spend $746 annually on repairs and maintenance with no major widespread issues reported. In the used market, it occupies a narrow space between standard Q60 models and the more powerful Red Sport models, valued at $32,750 used. Compared to the Lexus RC 350, the Q60 IPL delivers sharper dynamics but less interior tech. Infiniti Q60 Red Sport 400 Average Used Price: $32,750 Via: InfinitiThe Infiniti Q60 Red Sport 400 is the fastest coupe Infiniti ever sold, and it earns that title through output rather than gimmicks. Sharing the same VR30DDTT as the Q50 Red Sport and Nissan Z, it produces 400 hp and 350 lb-ft of torque, enough to push the coupe to 0–60 mph in around 4.5 seconds in rear-wheel-drive form. After all, in real world runs against the Nissan Z, it has shown very similar performance.Via: InfinitiAt $32,750 in the used market, buyers can choose between RWD offering better steering feel and lighter weight, while AWD improves traction off the line. Infiniti tuned the Q60 Red Sport specifically for coupe duty, with stiffer suspension calibration and wider tires than standard Q60 trims. The power-to-price ratio remains a strong selling point, especially when cross-shopped against cars like the BMW M240i. Interior tech lags newer rivals, and ride quality can feel firm on rough pavement, but the drivetrain performance still defines the ownership experience.Sources: Infiniti, Classic, KBB, Repairpal
