What kind of car is an Infiniti QX30?

The Infiniti QX30 is a compact luxury crossover SUV that Infiniti sold briefly from 2017 to 2019. It was developed with Mercedes-Benz engineering, built on the Mercedes MFA platform, and shared much with the GLA-Class.

Overview and classification

The QX30 sits in the subcompact luxury crossover segment, offering premium styling and a small-footprint package intended for urban buyers who want both practicality and upscale credentials. It was positioned as an entry point into Infiniti’s crossover lineup, distinct from larger models like the QX50 and QX60.

Key facts about the Infiniti QX30 include:

• Class: Subcompact luxury crossover (compact SUV).


• Platform: Mercedes-Benz MFA platform shared with the GLA-Class.


• Drivetrain: Front-wheel drive standard, optional all-wheel drive (AWD).


• Engine: 2.0-liter turbocharged inline-4, approximately 208 horsepower and 258 lb-ft of torque.


• Transmission: 7-speed dual-clutch automatic (DCT).


• Production years: Global introduction around 2017 with model years through 2019; production ended by 2019 in most markets.


• Market status: Discontinued in most regions; Infiniti did not continue the model beyond its short run.

In practice, the QX30 offered a premium interior, a crisp exterior design, and the engineering shared with Mercedes-Benz that underpinned its performance and packaging. It faced competition from other subcompact luxury crossovers such as the Audi Q3, BMW X1, and Lexus UX, but its Renault-Nissan-Mitsubishi alliance collaboration with Daimler gave it a distinct origin story in the segment.

Platform, engine and transmission

Platform and drivetrain

The QX30 was built on Mercedes-Benz’s MFA (Modular Front-engine Architecture) platform, a front-wheel-drive–biased architecture used by several compact models. Infiniti offered the QX30 with front-wheel drive as standard and an optional all-wheel-drive system for better traction in adverse conditions.

Engine and performance

Under the hood, the QX30 used a 2.0-liter turbocharged inline-4 engine producing about 208 horsepower and 258 lb-ft of torque. The powertrain was paired with a 7-speed dual-clutch automatic transmission, contributing to brisk acceleration characteristics typical of small premium crossovers in this class.

Market history and status

The QX30 represented Infiniti’s attempt to offer a premium, compact crossover with European-engineering influence, leveraging the shared Mercedes-Benz platform. However, sales in key markets, particularly the United States, remained modest, and Infiniti ultimately discontinued the model after the 2019 model year as part of a broader lineup refresh.

What it means in context

For buyers today, the QX30 exists as a niche, no-longer-produced option in Infiniti’s history. It remains notable for its cross-brand collaboration, its Mercedes-based underpinnings, and its place as a brief experiment in offering a compact, premium crossover with distinctive styling and a European-tuned driving experience within Infiniti’s lineup.

Summary

The Infiniti QX30 is a compact luxury crossover SUV that drew on Mercedes-Benz MFA technology and the GLA-Class for its mechanicals, offering a premium small-footprint option from 2017 to 2019. It combined a turbocharged 2.0-liter engine, a 7-speed dual-clutch automatic, and available AWD, but ultimately faded from the market as Infiniti refocused its lineup. Today it stands as a brief, distinctive chapter in Infiniti’s history of crossovers.
