All details on performance, efficiency, range and trunk space can be found in the technical comparison below – including user reviews for both models.
In the world of compact SUVs, the competition is fierce, and the Alfa Romeo Junior and Mazda CX-30 are two formidable contenders that offer an intriguing mix of performance, innovation, and style. Both vehicles bring their A-game, but how do they stack up against each other? Let’s delve into the technical details and innovations that set these models apart.
The Alfa Romeo Junior offers a diverse range of engine choices, including electric and petrol Mild Hybrid Electric Vehicle (MHEV) options. With power outputs ranging from 136 to 280 HP, it caters to various performance preferences. The electric variant promises an impressive range of up to 410 kilometers on a single charge, thanks to its 51 kWh battery capacity.
On the other hand, the Mazda CX-30 sticks with a more conventional approach, offering petrol MHEV engines that deliver between 140 and 186 HP. Its power and efficiency are evident, with fuel consumption as low as 5.7 L/100km, presenting a compelling option for those inclined towards traditional combustion engines.
Alfa Romeo provides both front-wheel drive and all-wheel drive options, paired with advanced transmission systems. The Junior features a reduction gearbox for its electric version and a dual-clutch automatic for the petrol variants, ensuring seamless power delivery and responsive handling.
Mazda's CX-30 offers the choice of manual and automatic gearboxes, tailored for front-wheel and all-wheel drive configurations. Its manual gearbox option might appeal to driving enthusiasts who value a more engaging driving experience.
When it comes to acceleration, the Alfa Romeo Junior stands out, with its fastest variant reaching 0-100 km/h in just 5.9 seconds. Meanwhile, the CX-30's best time is 8.3 seconds, which, while less thrilling, aligns with its focus on balanced performance and economy.
The eco-conscious will appreciate the Junior's electric variant, which boasts a CO2 efficiency class of 'A' with zero emissions. The petrol variants have varying levels of emissions, but the most efficient offers a commendable 4.5 L/100km consumption. The CX-30, despite its petrol-only lineup, maintains respectable CO2 efficiency levels, though not as low as the electric Alfa Romeo.
Both models comfortably seat five passengers, but there are differences in their trunk capacities. The CX-30 offers a slightly larger trunk capacity at 430 liters, compared to the Junior's maximum of 415 liters, making it a potentially better choice for those who prioritize cargo space.
Regarding dimensions, the Mazda CX-30 is longer and wider, measuring 4395 mm in length and 1795 mm in width. In contrast, the Junior is more compact, measuring 4173 mm in length and 1781 mm in width, which could be advantageous for urban driving and parking.
The Alfa Romeo Junior and Mazda CX-30 each have their unique strengths. The Junior's electric innovation and faster acceleration would appeal to those seeking cutting-edge technology and performance. The CX-30, with its slightly larger size and traditional petrol engine, continues to charm with its practicality and reliability.
Ultimately, the choice between the Alfa Romeo Junior and Mazda CX-30 depends on individual priorities—be it technological innovation and efficiency or tried-and-true performance and space. Both models demonstrate that the compact SUV segment is alive with innovation and style, offering something for every type of driver.
