The 2019 INFINITI Q70L represents the pinnacle of the Q70 sedan line, offering an extended wheelbase that prioritizes rear-seat passenger comfort and legroom. This luxury sedan features a choice of 3.7-liter V6 or 5.6-liter V8 engines, optional Intelligent All-Wheel Drive, and a focus on premium materials, positioning it as a competitive executive transport option in the late 2010s luxury market.
Evolution and Positioning of the Q70L
The INFINITI Q70L serves as the long-wheelbase variant of the standard Q70, specifically engineered to provide an additional 5.6 inches of rear-seat legroom. Released during a period when executive sedans were increasingly focusing on chauffeur-like experiences for rear passengers, the Q70L was designed to compete with the extended versions of the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. By 2019, the model had established itself as a mature platform, emphasizing a blend of traditional Japanese luxury craftsmanship and reliable, high-displacement engine performance rather than the aggressive downsizing seen in many European competitors at the time.
For buyers in 2026 looking at the secondary market, the 2019 Q70L remains a compelling choice for those prioritizing cabin space and mechanical durability. Unlike its successors which shifted toward smaller, turbocharged powerplants or hybrid architectures, the 2019 model retains the robust naturally aspirated V6 and V8 configurations that have garnered a reputation for longevity.
Powertrain Options and Performance Specifications
The 2019 Q70L was offered with two primary engine configurations. These engines are key factors in both the driving dynamics and the ownership costs of the vehicle today.
3.7-Liter V6 Engine
The entry-level powertrain for the Q70L is the 3.7-liter VQ37VHR aluminum-alloy V6. Utilizing Variable Valve Event and Lift (VVEL) technology, this engine produces 330 horsepower and 270 lb-ft of torque. It is a well-regarded engine known for its linear power delivery and high-RPM stability. When paired with the 7-speed automatic transmission, which features Adaptive Shift Control and manual shift modes, it provides a balanced driving experience suitable for both highway cruising and urban commuting.
5.6-Liter V8 Engine
For those seeking more substantial power, the 5.6-liter VK56VD V8 is the flagship engine. This unit outputs 416 horsepower and 414 lb-ft of torque. Featuring Direct Injection Gasoline (DIG) and VVEL, this V8 offers a significantly different character, providing deep torque reserves that make high-speed passing effortless. It is important to note that the V8 model was often positioned as the performance-luxury tier, often accompanied by higher trim levels and additional standard features.
Drivetrain Considerations
Both engines are available in rear-wheel drive (RWD) configurations, with INFINITI’s Intelligent All-Wheel Drive (AWD) available as an option. The AWD system is particularly notable for its ability to shift torque split from 0:100 front-to-rear to as much as 50:50, adapting to varying road surfaces and weather conditions instantly.
Dimensions and Interior Capacity
The "L" designation in Q70L denotes the extended wheelbase, which fundamentally alters the cabin’s utility. Understanding these dimensions is essential for prospective owners who prioritize passenger experience.
- Wheelbase: 120.1 inches (compared to 114.2 inches in the standard Q70).
- Overall Length: 202.0 inches.
- Rear Legroom: 41.8 inches.
The extra legroom is not the only benefit of the Q70L. The rear doors are also longer, providing a wider opening for ingress and egress, which is a significant advantage for those using the vehicle for professional transport or family use. The interior materials include standard Japanese Ash wood trim, leather-appointed seating, and an available semi-aniline leather package.
2019 Market Pricing and Value Retention
When the 2019 INFINITI Q70L was new, its pricing was tiered based on engine choice and drivetrain. The following table provides an overview of the original MSRP structure for the 2019 model year.
| Trim Level | Engine | Drivetrain | Original Base MSRP |
|---|---|---|---|
| Q70L 3.7 LUXE | 3.7L V6 | RWD | $51,300 |
| Q70L 3.7 AWD LUXE | 3.7L V6 | AWD | $53,850 |
| Q70L 5.6 LUXE | 5.6L V8 | RWD | $65,200 |
| Q70L 5.6 AWD LUXE | 5.6L V8 | AWD | $67,750 |
Note: These figures represent the base MSRP at the time of the 2019 release. Dealer options, packages (such as the ProACTIVE or Premium Select editions), and destination fees would have increased these amounts significantly.
In 2026, the valuation of a 2019 Q70L depends heavily on service history and mileage. Because the platform remained largely unchanged toward the end of its life cycle, buyers are often more concerned with the maintenance of the V8’s direct injection system or the V6’s water pump/timing chain health than they are with model-year variances.
Safety and Technology Features
The 2019 Q70L included a suite of safety technology, which was considered advanced for the era. The ProACTIVE Package, available on many units, included the following core safety components:
- Around View Monitor (AVM): Provides a virtual 360-degree view of the vehicle, using cameras mounted on the grille, side mirrors, and trunk.
- Lane Departure Warning (LDW) and Lane Departure Prevention (LDP): Uses a camera to monitor lane markings and alerts the driver if the vehicle drifts, with the ability to gently apply brakes to nudge the car back into the lane.
- Blind Spot Warning (BSW) and Blind Spot Intervention (BSI): Monitors blind spots and assists the driver in avoiding contact during lane changes.
- Predictive Forward Collision Warning (PFCW): Monitors the velocity and distance of the vehicle ahead of the one in front, providing an early warning of potential collision risks.
While 2026 standards for autonomous driving have advanced, the 2019 Q70L’s safety suite remains effective for everyday highway and urban driving, providing a secure environment for passengers.
Comparison: Q70L vs. Competitors
When evaluating the Q70L against its peers, the primary differentiator is the balance between size and mechanical simplicity. The BMW 5 Series of 2019 moved toward complex electronic systems and forced induction, while the Lexus GS (the closest Japanese competitor) ceased production shortly after.
The Q70L stands out as a "traditional" luxury sedan. It does not rely on forced induction to reach its horsepower figures, which appeals to owners who prefer naturally aspirated engine longevity. However, the trade-off is fuel efficiency. The 5.6L V8, in particular, carries a higher operational cost due to lower MPG ratings compared to the turbocharged six-cylinder engines found in German rivals of the same year.
Maintenance and Ownership Considerations
As the vehicle ages, prospective owners should be aware of specific maintenance items. The VQ37VHR engine is generally reliable but should be monitored for oil consumption as it crosses the 100,000-mile threshold. The 7-speed automatic transmission is robust, but fluid changes are recommended to ensure longevity, especially in models used primarily for city driving.
For the 5.6L V8, maintaining the direct-injection fuel system is critical. Ensuring the use of high-quality fuel and periodic inspection of fuel injectors will prevent performance degradation. The electronics, particularly the infotainment system, are reflective of 2019 technology; while functional, they lack the seamless smartphone integration found in current 2026 vehicles, though most 2019 models can be upgraded via aftermarket head units or simple wireless CarPlay adapters.
