How do I make an image like this, where the surrounding is blurred but the car isn’t.
My image is still and I’m using blender 2.82
Motion Blur -

Or Vector Blur if you’re doing it in post. Either way you will have to add some form of animated motion.

Or you could try to fake it with Directional Blur

To expound on organic’s response, your reference photo looks the way it does because the car is moving fast and the camera is panning at a speed relative to the car so that when the photo was taken, the car wasn’t moving relative to the photo’s framing. The foreground and background are moving in a lateral direction relative to the photo’s framing, so they are blurred laterally.
You’ll also notice that the wheels in the reference image have a radial blur because they are spinning around their axes.
To recreate this photo with the assets you’ve shown, you’ll need to do some parenting and keyframing. First, parent your car to your camera. Select your car, and Shift + select your camera and hit Ctrl + “P”. Choose Object (Keep Transform). Now, move your timeline up to about frame 30. With only your camera selected, press “I” and insert a Rotation keyframe. Back your timeline back to frame 1, and rotate your camera -179 degrees on the Z axis (that’s minus 179 degrees). Press “I” to insert another Rotation keyframe. Again, with your camera selected, jump back to frame 30. Switch to your Animation workspace at the top of the Blender window and in the bottom area (the Dope Sheet Editor), click on Channel > Extrapolation Mode > Linear in the menu area.
What you have done is to tell Blender that the camera and car are moving quickly (but not relative to each other). (Though motion blur works in Eevee, this method doesn’t keep your car focused, so you’ll need to use Cycles.) Make sure that in the Cycles Render Properties panel, you check the Motion Blur check box. You can adjust the amount of blur by sliding the shutter slider up and down from .5. Less than .5 makes things less blurry. More than .5 makes things more blurry.
You’ll now need to animate your car’s wheels to rotate around their axes, and you’ll get that radial blur on the wheels like in your reference photo. Let me know if you have any questions!

Thanks, I have already done that but then the car remains sharp clean while everything around is blurred, then the car look off.
I fixed that by making blur in photoshop. Thanks for the help anyway.
Vector blur is the usual thing that is done here … motion blur could be used for the wheels but it’s rather expensive.
And – “doing it in post,” with whatever tool works, is perfectly fine too!
