All they did was take a recording of the A45 AMG and play the sound to a video of the CLA250. Nice try by motor authority, but it doesn't translate well. At one point it looks like they sped up the video of a CLA cornering so it would match the sound of the A45 AMG.
I applaud them for the attempt, but it's not a good video.
Totally forgot about the little ol' Neon SRT-4s & MazdaSpeed3. I got a friend w/ the latter, Cobb-Tuning & all... it's a total pocket'rocket! And for the former, I rented one of those once- fun weekend!
Another extremely fun & interesting experience was a Brabus Smart-ForTwo rental...
From the article, i believe it is the genuine A45 AMG around the track (video and sound), they then use a standard CLA video (sped up at some points) purely for video, and play the CLA45 AMG note against that to compare the different engine sounds.
Looks like Merc sent only a sound recording in, and Motor Authority 'added' a video to the sound.
Interested in what it does sound like in the flesh.
We have a Vauxhall Astra VXR (Opel Astra OPC) in the family too, and it did come with a very nice sounding 2.0 4 Cylinder note. A new exhaust is now on it, and sounds a lot better.
AMG Boost had a great suggestion that we sticky a thread that contains posts/pictures from owners of their brand new CLA's... So, without further delay, here it is! Post pictures of your brand new CLA in this thread.
