Infiniti G: G35, G37 and G25 generations, engines and what to know when buying used
Infiniti G — the rear-wheel-drive premium sedan and coupe, produced from 2002–2015. We look at two generations, V6 engines, the most popular trims and what to check before buying a used Infiniti G, which often arrives in Lithuania from the USA.
Infiniti G in brief
The G series was Infiniti's sporty, rear-wheel-drive response to German premium sedans. Both sedan and coupe bodies were offered, along with a convertible with a folding hard top. Most versions had a V6 engine, with some featuring all-wheel drive.
Used market: G valued for lively V6 engine, balanced handling and price, often lower than a similarly aged BMW 3 Series or Audi A4. The model changed names: G35, G37 and G25, with the last sedans and coupes later receiving Q40 and Q60 designations.
Which generation to choose
The first generation (V35, circa 2002–2007) had a 3.5-litre V6 engine and was offered as a sedan and coupe. Today, it's the cheapest way to get a genuine Infiniti G, but the cars are now old, so mechanical condition is key.
The second generation (V36, circa 2007–2013) got a more modern design, more equipment, a 3.7-litre V6 (G37) and a smaller 2.5-litre V6 (G25). Most buyers chose it for better comfort, safety and equipment.
Engines and gearboxes
The most common engine in the first generation is the 3.5-litre V6 (around 260 to nearly 300 hp, depending on the version and year). In the second generation, the popular 3.7-litre V6 (around 320–330 hp) and the 2.5-litre V6 (G25, around 220 hp) are notable.
Transmissions come in manual (6-speed) or automatic (5, 6, or 7-speed, depending on the year). Rear-wheel drive was standard, while all-wheel drive (x versions) was an option.
What to check when buying a used Infiniti G
Check if the engine isn't consuming too much oil, as some V6 models from that era had increased oil consumption. Inspect the cooling system, oil leaks, and engine noise when cold.
Test the automatic transmission and all-wheel-drive system if equipped, evaluate the ride, electrical features (climate control, windows), and the condition of the seats and steering wheel. If the car is from the US, ensure there's no accident history and review the service records.
