Cadillac CT4 and CT5 high-performance V cars spied

This summer, Cadillac teased much more impressive V-series models than the lukewarm CT4-V and CT5-V. Now we get a better look at both super sedans, each one boasting more aggressive, but subtle visual upgrades. Normally we would talk about the visual changes to each car individually, but the changes are nearly identical between the cars. They both get deeper chin spoilers and lower side skirts. The lower grille opening now features slatted sections on either end. The headlights, main grille and hood all look unchanged from the regular V models. The same goes for the rear bumpers and tailpipes. The rear spoilers on both are much taller, though. The wheels on the CT4 look about the same as the CT4-V, but the CT5 wheels look a bit different with more detail. We also get a good look at the wheel-filling brakes. Cadillac hasn't said anything concrete about the specifications of the hotter CT4 and CT5 models, except that they'll definitely be faster than the revealed V models. One thing we do know, thanks to our spy photographer's video from earlier this year (shown above), the CT5 will get a V8. Our bet is on it being the Blackwing twin-turbo V8 that's available in the CT6-V and CT6 Platinum. It would probably have at least the same output at the CT6-V at 550 horsepower and 640 pound-feet of torque. Expect the 10-speed automatic transmission to carry over with it. This drivetrain would also open up the possibility of all-wheel drive. As for the fast CT4, it could potentially revive the ATS-V's twin-turbo V6 with 464 horsepower and 445 pound-feet of torque. It would probably also get a 10-speed automatic and maybe all-wheel drive as an option.

2016 Hennessey CTS-V is properly ridiculous with 1,000 horsepower

We truly live in a halcyon era of automotive performance with models like the latest Shelby GT350 Mustang and 707-horsepower Challenger Hellcat. And now Hennessey Performance Engineering is bringing something with absolutely obscene power to the world with its tuned 2016 Cadillac CTS-V that packs a ludicrous 1,000 horsepower. The latest CTS-V isn't even on sale yet but should be a powerhouse straight from the factory. Under its carbon fiber hood is a 6.2-liter supercharged LT4 V8 with 640 horsepower and 630 pound-feet of torque that makes the sedan capable of a 200-mile-per-hour top speed. Hennessey's take ditches the blower in favor of two turbos to feed air to the engine. To cope with the extra power, the mill gets upgrades like forged aluminum pistons and forged steel parts for the rods and crankshaft, and transmission upgrades are also necessary to make it all work. Buyers can even spec things like carbon-ceramic brakes and a widebody kit to allow for bigger tires. The crazy numbers are leading to some big performance claims from company founder John Hennessey. "I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph," he said in the Caddy's announcement. Hennessey is building just 24 of these 1,000-horsepower sedans for the 2016 model year. However, for those that want to keep the supercharger under the hood, the company is also offering upgrades with 750 hp and 800 hp for the CTS-V too. All of them sound absolutely ridiculous in an utterly fantastic way. 2016 HPE1000 Twin Turbo Cadillac CTS-V Texas Tuner Plans to Build World's Fastest 4-Door Sedan Sealy, Texas-When the next generation Cadillac CTS-V hits the streets later this year, it will have 640+ hp and a top speed of nearly 200 mph. To the team at Hennessey Performance Engineering (HPE), this is a good starting point. The company plans to pick-up where they left off with the last gen CTS-V by producing the world's fastest 4-door sedan: The Hennessey HPE1000 Twin Turbo CTS-V. "A couple of years ago, the State of Texas gave us the opportunity to test one of our specially tuned CTS-Vs – our VR1200 Twin Turbo coupe. It ran 221 mph (356 km/h) on State Highway 130, near the Circuit of the Americas", said company founder, John Hennessey. "It was still pulling on when we ran out of road. I believe that our 2016 Twin Turbo CTS-V will have a top speed approaching 240 mph (386 km/h)". Hennessey plans to offer a limited run of only 24 units for the 2016 model year.

Facelifted Cadillac ATS spied completely uncovered

The Cadillac ATS makes for a pretty svelte little coupe, and General Motors appears to know it, because multiple, completely undisguised prototype sedans have been spotted testing wearing what look like many of the forthcoming coupe's body parts.
Not only does it wear at least the outline of the brand's new, broader crest, it has the same front air dam with continuous chrome strip found on the coupe. The only real difference is that it has the somewhat taller side view mirrors from the sedan, rather than the narrower, longer ones from the coupe. Around back, the changes are harder to spot because the test car is outfitted with an unpainted lower bumper. However, it seems to lack the chrome strip that offsets the lower portion of the coupe from the sedan.
The ATS sedan is already a looker, but it is good to see Cadillac is taking a second pass using what it learned on the coupe. There's no word yet on when this revised sedan is going to hit the streets - let alone what changes will take place beneath the skin - but we're thinking it looks about right for 2015.
