WEY 03

As the SUV segment continues to grow in popularity, car enthusiasts are presented with a diverse array of options catering to various tastes, driving styles, and technological preferences. In this comprehensive comparison, we delve into the features and specifications of two standout models—the GWM WEY 03 and the SEAT Ateca. Both vehicles represent their brands’ commitment to innovation and performance, but they do so in notably different ways.

Ateca

Powertrain and Performance

The GWM WEY 03 is particularly notable for its advanced powertrain, offering a Plugin Hybrid option. With a robust power output of 442 HP generated by its 2.0L four-cylinder engine, combined with an electric motor, it delivers exceptional torque of 685 Nm. This fierce combination allows the WEY 03 to achieve an impressive 0-100 km/h acceleration time of just 5.3 seconds, which is remarkable for an SUV.

On the other hand, the SEAT Ateca caters to a different audience with its conventional petrol and diesel engine options. The range starts with a modest 116 HP, extending up to 150 HP for those seeking a spirited driving experience. The Ateca's acceleration varies from 9 seconds for the more powerful variants to 11 seconds, showcasing a less exuberant but still respectable performance compared to the WEY 03. With a maximum speed of 183 km/h to 202 km/h, depending on the engine choice, the Ateca provides solid performance without being overly aggressive.

Fuel Efficiency and Emissions

One of the standout features of the GWM WEY 03 is its hybrid powertrain which boasts a remarkable fuel consumption of just 0.5 L/100 km. This efficiency is complemented by a CO2 emission rating of only 15 g/km, making it an environmentally friendly option in the SUV market. The electric range of 139 km further enhances its appeal for eco-conscious drivers who may prefer to run on electric power alone during shorter trips.

In contrast, the SEAT Ateca’s fuel consumption ranges from 4.9 L/100 km for the most efficient diesel engines to 6.4 L/100 km for the more potent petrol variants, with CO2 emissions ranging from 129 g/km to 144 g/km. While the Ateca does not match the WEY 03’s environmental credentials, it offers a good balance of performance and efficiency for traditional engine-lineups.

Dimensions and Space

When it comes to dimensions, the GWM WEY 03 is larger, measuring 4688 mm long, 1890 mm wide, and 1730 mm in height. Its size contributes to a spacious interior and cargo space, offering 517 liters of trunk capacity—ideal for families and active lifestyles.

The SEAT Ateca, while slightly smaller at 4381 mm long, 1841 mm wide, and 1601 mm high, still offers a commendable trunk capacity of 510 liters. With similar passenger accommodations for five, both SUVs support a comfortable ride, but the WEY 03's larger footprint could be a deciding factor for those needing extra space.

Interior Technology and Features

Inside the GWM WEY 03, modern technology takes center stage with an emphasis on driver comfort and connectivity. The model features a high-tech interface, advanced infotainment system, and driver-assistance technologies, all aimed at elevating the driving experience. The hybrid setup also allows for intuitive energy management, enabling users to maximize efficiency.

The SEAT Ateca, while perhaps less technologically advanced than the WEY 03, doesn't skimp on features. Its infotainment system is user-friendly and includes modern connectivity options. Smart assistance aids are available in higher trims, making it easier to navigate and ensure safety on the road.

Conclusion: Which SUV Reigns Supreme?

Choosing between the GWM WEY 03 and SEAT Ateca boils down to personal preference and priorities. If cutting-edge hybrid technology, exhilarating performance, and exceptional fuel efficiency top your list, the WEY 03 stands out as the sophisticated choice. However, for drivers seeking reliable performance, a traditional engine experience, and good overall value, the Ateca remains a formidable contender.

Ultimately, both models bring unique strengths to the table, reflecting their respective manufacturers' visions and catering to the diverse demands of today’s SUV buyers.

Exactly the right size. Just still suitable for families. The touchscreen is nicely integrated, not just a tablet stuck on — it flows into a console with the Virtual Cockpit and still has real buttons for the most important everyday functions. Perfect mix. My comparisons were the new 2er Active Tourer, the B‑Class and the Kia Sportage. The Ateca won for me overall by a clear margin, but it was a bit overpriced in comparison. And it wasn't my dream car. More a "practical car." Cheap is a thing of the past.

The speedo shows up to 218 km/h, but it really struggles to get beyond about 180. Above 150 km/h it also gets noticeably louder, but still acceptable. For people who like to glide along comfortably it's a very good choice; for those who like to drive fast, rather not. It handles dirt tracks well thanks to its ground clearance, and it also takes corners very well. Already somewhat sporty, agile.

Folding tow hitch, partially autonomous driving, lots of useful driver aids, a good multimedia concept, etc., as well as the very good seating position and controls make it attractive.

My previous 2.0L diesel was noticeably better to drive at higher speeds. But yes, times have changed. Not everything is perfect, but overall it has earned its 5 stars when you factor in the price and compare what you get for your money. 1.5 TSI Xperience DSG +XL + ***

The Seat Ateca is a very affordable SUV with excellent handling and plenty of space for the whole family. A companion that can do it all and is equally suited to everyday use as to long trips fully loaded. A very good choice for the active family that needs a car that fits most needs.

+ Great, firm seats, large boot for such a compact car, good fuel economy, lots of interior space, uncomplicated controls, very agile and safe handling, good build quality, very good steering, good braking performance, relatively small turning circle
- Very poor voice control and navigation, cockpit display too small with very small fonts and symbols, steering wheel too thin, seats too flat despite electric adjustment, poor engine soundproofing, tank far too small, complicated maintenance (oil change appalling), undersized rear brake, fuel filler on the wrong side, sound almost without bass (Beats)
