The world is adjusting to the idea of a dual-tier V-Series strategy, wherein previous V-Sport models get the V-Series badge (like the CT5-V), while “true” next-level models are called V Blackwing (such as CT5-V Blackwing). The CT5-V was revealed in late May, and we recently caught a slew of prototypes of the upcoming Cadillac CT5-V Blackwing testing well ahead of the high-performance sedan’s debut.
This isn’t the first time we’ve seen the CT5-V Blackwing in public. In fact, General Motors paraded the hardcore four-door out at the 2019 Belle Isle Grand Prix, where it briefly appeared on track alongside a CT4-V Blackwing prototype. These photos, first published by our colleagues at the Cadillac Society, give us a slightly better look yet at the car and more cleanly display the revised front air intakes and different grille.
The prototypes pictured here also feature wider alloy wheels with Michelin tires and what appear to be slightly widened wheel arches. Notably, the heat extractors present on the back of the front fenders of the prototype GM brought to Belle Isle are tough to make out on these cars, but they are still there, obscured by the concealing camouflage wrap. The test cars don’t feature the lip spoiler spotted on the Belle Isle car, either – but again, we expect the production model to offer a spoiler.
At this point, it’s not clear if the CT5-V Blackwing will feature Cadillac’s twin-turbocharged 4.2-liter Blackwing V8 engine, which serves in the Cadillac CT6-V, or another V8 engine from the vast GM powertrain line. A rumor we heard previously indicated that one of GM’s 6.2-liter supercharged V8s may appear in the car – though we’re sure that some would rather see the more modern twin-turbo mill under the hood.
A video captured by our spies in the summer gives us a look at the sound the Cadillac CT5-V Blackwing makes while accelerating. In that video, a prototype emits an exhaust that appears to sound similar to other GM products with the supercharged 6.2-liter LT4 engine, like the outgoing CTS-V. However, others note that the engine and exhaust note is different.
In addition to a more powerful V8 engine, the CT5-V Blackwing will also feature performance suspension upgrades and more robust brakes. Rumors that a manual transmission will be on offer persist, though we can’t confirm it for this particular model. The most robust version of GM’s 10-speed automatic transmission will be present and accounted for.
Also of note is the fact that these prototypes were traveling in a convoy that also included the current-generation BMW M5 and the third-generation Cadillac CTS-V. The M5 can accelerate from 0-60 mph in 2.8 seconds and reach a top speed of 190 mph with the top speed limiter removed. Meanwhile, the outgoing CTS-V was capable of 0-60 performance in 3.7 seconds and a top speed of 200 mph.
