XTOOL D7 vs. D8: Performance (Round 1)

Bi-Directional Control
36+Service Functions38+
ECU coding
Topology map

While D8 and D7 may seem similar in capabilities such as:

  • full system diagnostics,
  • bi-directional control,
  • 23 common service functions,

The D8 has some significant advantages that make it stand out.

From my first-hand experience, I was impressed by the D8’s speed. 

Thanks to its 1.8GHz Quad-core processor, D8 scans systems and performs active tests at remarkable speed, significantly faster than D7. It was so efficient that I found myself getting through jobs quicker.

In addition, D8’s active tests are far superior to D7’s. It even has a “special functions” button under each sub-section, which the D7 lacks entirely. 

For instance, when I tested the “windows” system, the D8 offered additional options, such as a one-touch feature that rolled down the window. This makes repairs more convenient and efficient.

But what truly sets the XTOOL D8 apart is its ECU coding and Topology map

XTOOL has recently added the Topology function in response to customer requests, demonstrating their commitment to meeting customers’ needs. Their dedication to improving their product has won me over.

Overall, the XTOOL D8 is the clear winner in terms of performance.

Winner: XTOOL D8

XTOOL D7 vs. D8: Vehicle coverage (Round 2)

CAN FD protocols

When it comes to vehicle coverage, it’s hard for me to declare a clear winner.

This is because both tools are equally impressive and can handle most OBD2 vehicles worldwide.

However, the XTOOL D8 does have one advantage over the D7. It is equipped to work on CAN FD protocol vehicles, which allows it to scan and repair the latest GM cars

This may be a deciding factor for mechanics who frequently work on these types of vehicles.

However, if you do not typically work on GM cars, then the XTOOL D7 is still a reliable and versatile option.

Winner: XTOOL D8

1G- 32GStorage2G- 64G
Wireless connection

Having used both the D7 and D8 models, I can confidently say that the D8 outperforms the D7 in several key areas.

Firstly, the D8 boasts an upgraded 10,000mAh battery compared to the D7’s 4,000mAh battery. Therefore, you can use the D8 for up to 2.5 times longer than the D7 before recharging. 

As someone who relies on the scanner for long periods throughout the day, like me, having a long-lasting battery is crucial to avoid any interruptions during repair work.

Secondly, the D8’s larger storage capacity of 64GB is double that of the D7’s 32GB. With more storage, you can save more data and records, making tracking the history of each vehicle you work on easier.

Thoughtful design is also a plus. D8 is upgraded with a 1-inch larger screen, kickstand, and camera. These features make repairs more convenient and efficient, saving time and effort.

After weighing the differences and benefits, I find the extra $200 investment in the XTOOL D8 is well worth it for mechanics looking for a tool to keep up with their work demands.

Winner: XTOOL D8

XTOOL D7 vs. D8: After-sale service (Round 4)

3 yearsFree updates3 years
Customer support

I can confidently say that XTOOL’s after-sale service deserves more than just 5 stars.

One of the key features that set XTOOL apart from its competitors is their offer of 3-year free updates, which is unmatched in the market.

This is a key reason why I recommend XTOOL products to fellow mechanics.

What’s more impressive is that XTOOL releases updates almost every day, whereas other brands only update once a month or even once a year.

If you encounter any issues while using their product, you can report it to XTOOL, and they will resolve it in less than a week

This exceptional level of service is reflected in numerous customer reviews, and I have personally experienced it myself.

XTOOL’s dedication to fixing bugs and glitches has resulted in a product that runs smoothly and is updated regularly.

In a nutshell, XTOOL’s customer support is top-notch, and they always strive to treat their customers right until they are fully satisfied.
