It could if I could find the actual article...

Top Gear is just car related entertainment. Their extra downforce can easily mean lift reduction. In my opinion everything here is just as it should be. 400 N @ 250 km/h means about 200 N @ 200 km/h. So the lift at rear end would be about 350 N @ 200 km/h without the spoiler. That sounds totally believable. SportAuto measured 380 N lift for Renault Megane RS.

Would the reduction of lift not come from the creation of negative lift? Is negative lift not "downforce"?
"Typically the term "lift" is used when talking about any kind of aerodynamically induced force acting on a surface. This is then given an indicator, either "positive lift" (up) or "negative lift" (down) as to its direction. In aerodynamics of ground racing (cars, bikes, etc.) the term "lift" is generally avoided as its meaning is almost always implied as positive, i.e., lifting the vehicle off the track. The term "downforce", therefore, should always be implied as negative force, i.e., pushing the vehicle to the road."
(
Downforce)
Knowing the lift generated with the AMG aero package does us no good without knowing what the amount of lift measured *before* the aero package was added was. If lift was higher before the aero package, then the package created negative lift (downforce). Right? That's why I wanted to read the article to see if they listed the lift prior to the addition of the aero package.

Just take a look at those pictures you posted. What do you see at the front end of CLA? There are huge holes for brake cooling and probably for charge air too.

You're right! The front end most likely creates more drag... I have never said that it doesn't.
