AceCar T800 review

It may not show as many parameters as other heads-up display units, but the AceCar T800 displays the basics: speed, compass heading as well as longitude and latitude.

Among the least expensive HUDs it can run acceleration and braking tests, although it lacks basics like on-board diagnostic warnings and the warranty only lasts six months. Overall, the T800 can provide automotive insight that won’t distract the driver.

Price and availability

This $46 heads-up display is among the least expensive devices of its kind. AceCar makes several other automotive add-ons, including the $48 Tesla Model 3 HUD that works with Tesla’s entry-level motor and the slightly pricier Model Y.

Design and features

The AceCar T800 goes its own way when it comes to design, with a direct view display rather than a windshield projection setup. At 2.2-inches high, it only slightly obstructs the driver’s view of the road ahead. It also weighs 1.9-ounces, making it one of the lightest heads-up displays available.

Canon says the animal recognition on the R6 is currently only for cats, dogs and birds, but that doesn’t stop the camera from focusing on anything it thinks is an eye or a head. For subjects as small as bees, the R6 was able to find the insect’s head and stick with it as long as it was on a flower. However, we failed while trying to track the bees as we were too slow to follow the busy bodies, and the out-of-focus images were no fault of the camera but the user’s inability to keep up.

Canon’s new Dual Pixel CMOS AF II system allows focusing to be done on-sensor and gives you a whopping 6,072 AF points to choose from – higher than the R5’s 5.940 user-definable points. These points cover the entire horizontal frame and 90% vertically, which is more than what most intermediate-level cameras offer.

Long story short, there’s no other camera in this class that can do what the R6 does in terms of autofocus, at the speed at which it does, and, arguably, at the price point that it does.


  • Best-in-class full-frame IBIS
  • Up to 20fps burst speed
  • Improved battery life

With Canon’s latest Digic X imaging engine under the hood, you’d expect the R6 to be a top performer like the 1D X Mark III where the processor debuted. And our tests prove that it is.

The R6 is capable of capturing 5472×3648 pixel images (as compared to the larger 8192×5464 size on the R5) in JPEG or 14-bit RAW files. Compressed RAW is also available, but our file format pick is the 10-bit HEIF. To shoot in this format, you need to enable HDR PQ, which will swap JPEG out for HEIF, and you can convert back to JPEG in-camera as well.

To match the camera’s burst speed, it’s important the R6 has an equally impressive buffer memory. While a lot will depend on the memory card you’re using, the camera handled a burst of about 315 frames during our tests without even thinking about it to a UHS-II SD card.

In fact, you’ll easily be able to save over 1,000 JPEGs or compressed.CR3 RAW files to a UHS-II card without the camera slowing down. If you’re shooting uncompressed RAW, then buffer depth will drop significantly to 240 consecutive files. Either way, that’s way more than what most people will need.

Image quality

  • Excellent color reproduction
  • Disappointing dynamic range in JPEGs
  • Good ISO performance

Most users would be concerned with the resolving power of the 20MP sensor. As long as you aren’t doing a side-by-side comparison with the R5 – which would be highly unfair – we found the R6 can hold its own.

Images pop with color without appearing oversaturated, as has always been Canon’s trademark. Details are good for the most part but we did find the R6 struggles during bright sunlight.
