The Infiniti Q30 is a subcompact executive car built and sold by Nissan's Infiniti luxury brand between 2016 and 2019. The Q30 is built on the third-generation Mercedes-Benz A-Class platform to create a small, premium hatchback.

Infiniti's QX30 is built on the Mercedes-Benz GLA architecture and uses engines made by Mercedes.

Infiniti's volume line, the G series, will get a Mercedes-Benz engine as part the global alliance between Daimler AG and Renault-Nissan, the story AutoWeek blew wide open at the end of March.

For those of you who don't know the situation with the QX30, the basic gist is that Infiniti and Mercedes-Benz decided to work together developing it. Mercedes-Benz makes the platform, the engine and apparently a lot of the switchgear, while Infiniti actually assembles the vehicle.

"INFINITI is one of only two returning winners for this year's Ward's 10 Best Engines competition, and it happened with virtually no debate among the judges," said Tom Murphy, Managing Editor, WardsAuto.

Infiniti cars are so popular because they're designed to be very compact yet spacious. They have power steering and brakes, making them very easy to operate. The engine is also very powerful, giving it great speed. In fact, it's almost impossible not to get over the speed limit when driving one of these cars.
