Spec Check: Cadillac CT5-V Blackwing vs. AMG E63 S, BMW M5 CS, and Audi RS7


The Cadillac CT5-V Blackwing is lastly right here, and the spiritual successor to the CTS-V we beloved a lot is a good heavier shot throughout the Atlantic than we anticipated. Its 6.2-liter supercharged V-Eight kicks out a (frankly ridiculous) 668 horsepower and 659 lb-ft of torque. That’s not simply “lots,” it’s sufficient to place the the European super-sedan aristocracy—the BMW M5 CS, Mercedes-AMG E63 S, and Audi RS7—to disgrace.

Earlier than we get began, it’s worth noting that both the CT5 and its smaller sibling, the CT4, are what we usually confer with as “tweeners,” that means their specs land them between established segments. Say, their general size and wheelbase locations them in a single phase, however their pricing places them in one other. The non-V CT5’s base value, for instance, is $37,990, whereas the BMW 5 Series starts at $55,195—and even the smaller Three Sequence runs $42,245 to start out. This, even though the wheelbase measurements of the CT5 and the 5 Sequence are inside 1.1 inches of one another (116 inches to 117.1). So, the CT5 is not-quite-a-5er, not-quite-a-3er, making the CT5-V Blackwing closest to, effectively, the extra highly effective uber-fast midsizers than much less highly effective, smaller stuff such because the BMW M3 sedan or Mercedes-AMG C63. How does the Caddy do towards the M5, E63 S, and RS7, then?

Cadillac CT5-V Blackwing vs. All people: Weight

Let’s speak weight. Whereas we haven’t tested the new RS7, we did recently weigh its wagon sibling, the RS6 Avant. The RS6 weighs in at a hefty 4,862 kilos, and it’s secure to imagine the RS7 shaves a number of kilos off that curb weight. Mercedes-AMG claims the E63 S sedan ideas the scales at slightly below 4,500 kilos; we additionally lately put the E63’s wagon counterpart on the scales, and it weighed in at 4,568 kilos. The final M5 we examined was a non-Competitors-spec M5 from 2018 and it weighed in at 4,268 kilos. The new, more powerful M5 CS promises to be lighter than the already slimmed-down M5 Competitors, and can most likely come it at round 3,900 kilos all in.

The Cadillac’s weight, then again, is a little more elusive. At Automotive of the Yr analysis final yr, we examined a daily CT5 with the two.7-liter four-cylinder engine that tipped the scales at a comparatively svelte 3,693 kilos. The Blackwing, then again, has a greater than twice-as-big engine, however lacks the all-wheel drive included on the M5, E63, and RS7. The Blackwing additionally comes with the choice for carbon ceramic brakes and may be had with Magnesium wheels, each of which cut back mass. To not point out the Caddy’s liberal carbon fiber trim. That implies that, even when the CT5 gained 200 kilos within the transformation to Blackwing spec, it might nonetheless weigh a lot, a lot lower than all of its German opponents.

Cadillac CT5-V Blackwing vs. All people: Energy

As for what’s underneath their respective hoods, the story is way the identical from Audi, BMW, and Mercedes. All of these sedans include twin-turbo V-8s. The Mercedes and Audi each displace 4.zero liters, the BMW displaces 4.4. Now, only for a second, contemplate that we reside in a world the place the RS7, with its 591 horsepower and 590 lb-ft of torque, is the least highly effective member of this quartet. That’s simply nuts.

Anyway, the Mercedes makes a mighty 603 hp and 627 lb-ft of torque, whereas the recently-announced M5 CS makes 627 horsepower and 627 hp and 553 lb-ft. These figures merely contextualize what you already knew: The lighter, extra highly effective CT5 Blackwing goes to have a vastly superior weight-to-power ration when in comparison with the M5, E63 S, and RS7.

Factor is, the CT5-V BW won’t be succesful launching as arduous as its all-wheel-drive opponents, given its rear-wheel drive, however that’s a choice Cadillac claims was intentional. The automaker left AWD off the desk as a result of, on a racetrack, the additional pushed wheels apparently don’t make the automobile any sooner. Briefly, the acceleration occasions of the rear-drive-only CT5-V Blackwing and its opponents could also be extra clustered than you’d anticipate, given the Cadillac’s power-to-weight benefit.

Cadillac CT5-V Blackwing vs. All people: Quick Stuff and Value

Different trick, go-faster bits are widespread to each entry on this foursome. All of them include the choice for ceramic brakes, light-weight wheels (although it have to be talked about solely the Caddy’s are unique magnesium), and adjustable dampers. Nonetheless, solely the Cadillac gives the choice of a six-speed guide transmission; the BMW, Mercedes-AMG, and Audi are all automatic-only. A 10-speed auto is accessible, however the stick alone could be a great purpose to go for the Blackwing.

One other good purpose to think about the Cadillac? {Dollars} and cents. Bear in mind what we stated concerning the CT5 being a tweener? That offers it a large value benefit, even once you massively scale-up the efficiency. The E63 S begins at $108,495, the RS7 at $114,995, and the M5 CS breaks the financial institution at $142,995. The Caddy, then again, begins at $84,990. So, simply to get all of it straight, the CT5 Blackwing makes (approach) extra energy, weighs much less, gives a guide gearbox, and prices greater than $20,000 lower than its closest rival. This factor could be the discount of the century—however we’ll must put it head-to-head with its opponents and drive them unexpectedly to see which one really comes out on high.
