This is an overseas car news: soon, Volvo EX90 will be launched, and Master Jiao believes that many students are paying attention to it. In this article, we will talk about this car, another pure electric SUV from Volvo.
Unlike the previous Volvo electric SUV, the EX90 is the first model under Volvo's own platform. At this time, some students may say, "Isn't the EX30 also Volvo's?" "Yes! However, the EX30 is based on Geely's SEA vast platform architecture, while the EX90 is a product of Volvo's own SPA2 platform.
The Volvo EX90 was bounced in one phase, mainly because the vehicle software conflict was not resolved. At the time of writing this article, Volvo has not yet solved this BUG, but the delivery of the product cannot be delayed, as for when it will be solved? Volvo promises to handle it perfectly, but time doesn't tell.
On paper, the EX90 performance is still good. Although the vehicle is built on a 400V platform, the 110-kWh battery pack can withstand up to 250 kWh of charging power, which is even faster than the Kia EV9 that supports the 800V platform architecture (the actual voltage is close to 600V).
Volvo explains how it does this. They used a pre-inverter with silicon carbide technology to improve the overall charging efficiency. At present, no traditional car company has adopted this technology. The EX90 has a range of more than 300 miles (480 km) on a single charge.
The biggest advantage of the silicon carbide front inverter is the linear acceleration performance, with a total output of 402 hp and a peak torque of 730 N·m with dual motors. Additional performance is unlocked with the optional Performance Package, which makes 510 hp and 910 N·m of torque. It's worth noting that the performance unlock is only a breakthrough at the software level, which means that even if you choose the 402 horsepower version, you can actually meet the peak standard of the performance package in terms of hardware.
In the past few days, Volvo has conducted EX90 test drives in North America, and overseas media said that this tram is not easy to drive. In particular, the steering wheel is not very accurate, and in addition, due to the high performance of the motor, the tires are subjected to undesirable limits, and the tire grip is insufficient in high-speed cornering.
The cabin is quiet. The four windows are laminated soundproof glass, regardless of the size of the body, the drag coefficient of the vehicle is only 0.29Cd. In addition, the sound quality of the 25 speakers in the car is still good, and it comes with active noise cancellation. The air suspension in the chassis is comfortable, and the bump filtering performance is good, making the normal ride very quiet.
Anti-human design is coming! There are only two front window control buttons, and the back button is the first row and second row window switch buttons. Why break with tradition and use these over-designs to make quiet interiors annoying. Don't forget, Volvo you haven't fixed the EX90 software bug yet, and it's not a good idea to reduce or eliminate the physical buttons you use frequently.
Through the test drive experience, foreign media found that although the whole vehicle has a mobile phone key function, the connection success rate is too low. Most of the time, the phone locks the car and cannot be unlocked again. What's even more puzzling is that there is no one in the back seat, and the reminder that the seat belt is not fastened will prompt that someone is not wearing a seat belt, and it will ring non-stop.
Standing outside the car, you may have noticed that the EX90 is equipped with a lidar, which is the key to realizing intelligent driving technology, and in the case of Volvo, improving the safety of the vehicle is the most important. This lidar was developed by Luminar, and can detect the vehicle's surroundings in real time with vehicle sensors. Unfortunately, the intelligent driving function has not yet been realized.
Volvo said that it has now controlled the software stack of the entire car, and it is only a matter of time before the software bugs are resolved. If the software issue is not resolved, it will be difficult for the all-electric SUV to be sold in North America for more than $80,000. Compared with the current competitors on the market, EX90 still has a lot of problems, especially when the software problem is not solved, and competitors are constantly eating the market. Volvo itself is in a hurry.
Although software issues plague the Volvo EX90, as an electric car, it has class-leading range and charging efficiency. The 400V architecture beats some of the competing fake 800V architectures, at least in terms of technical materials, and the EX90 has no problems.
