Positioned above the M35 and M37 in the Infiniti lineup, it was developed for buyers seeking stronger performance without sacrificing comfort. The M45 offered a balance of smooth cruising, executive-class luxury, and commanding road presence. It represents Infiniti’s effort to challenge established European sedans with a distinctive offering.

The exterior of the M45 is bold and upscale, with strong lines and elegant proportions. Its wide stance and long hood highlight its performance-oriented design. Premium elements such as xenon headlights, chrome accents, and stylish alloy wheels enhance its luxury appeal. Subtle aerodynamic details give it a sporty edge while maintaining its executive image. Overall, the M45 projects authority and refinement on the road.

Inside, the Infiniti M45 offers a spacious and premium cabin crafted with attention to detail. High-quality leather, wood or aluminum trim, and soft-touch materials emphasize luxury. The driver and passengers benefit from power-adjustable seats with heating and ventilation options in higher trims. Advanced features such as a premium Bose audio system, navigation, and intuitive climate control ensure a refined driving experience. Rear seating provides ample comfort for longer journeys.

Safety Features

The M45 is equipped with a comprehensive range of safety technologies suitable for a flagship midsize sedan. Standard features include multiple airbags, ABS with EBD, traction control, and electronic stability systems. Advanced options in higher trims include adaptive cruise control, lane departure warning, and blind-spot monitoring. The solid body construction enhances crash protection, giving passengers greater confidence and peace of mind.

Engine Trims

The Infiniti M45 is powered by a 4.5L V8 engine, delivering strong acceleration and refined performance. Paired with a 5-speed automatic transmission, it provides smooth shifts and responsive handling. Rear-wheel drive is standard, with all-wheel drive available in select markets. The V8 emphasizes power and smoothness, offering a more dynamic drive compared to its V6 siblings.

Maintenance

Maintenance for the M45 is more demanding than the M35 or M37 due to its larger V8 engine. Service costs and fuel consumption are higher, but Infiniti’s global service network ensures reliable upkeep. Spare parts are generally available, though luxury-specific repairs may add to ownership costs. With regular maintenance, the M45 delivers long-term reliability and performance for discerning owners.

Competitors

The Infiniti M45 competes with luxury sedans such as the Lexus GS 460, BMW 550i, Mercedes-Benz E-Class V8, and Audi A6 V8. While some rivals may surpass it in prestige or technology, the M45 distinguishes itself with Japanese dependability, smooth V8 performance, and strong value. It appeals to buyers who want a premium sedan that balances power, refinement, and long-term reliability.
