Tuned Air Inlet And Outlet Resonators

The good looking 2016 ATS-V coupe and sedan was released at the Los Angeles auto show and @AutoReportsUSA was there on press day to see the cars in person. The ATS-V features the first application of the Cadillac Twin Turbo engine in the V-Series, with unique features that expand its performance range and support track capability. With the eight-speed automatic, the ATS-V reaches 60 mph from a standstill in only 3.9 seconds and achieves a top speed of more than 185 mph (299 kph). Tuned air inlet and outlet resonators, aluminum cam covers and other features that contribute to exceptional quietness and smoothness. The standard TREMEC TR6060 six-speed manual transmission has a strong track record proven in the supercharged CTS-V series. Launch control - Also part of the Performance Traction Management system, it enables maximum off-the-line acceleration. The TR6060 transmission is used with a dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia.


The new Hydra-Matic 8L90 eight-speed paddle-shift automatic transmission is available in the ATS-V. Designed and built by GM, it delivers world-class shift times that rival the best dual-clutch designs. For performance driving, the transmission offers full manual control via steering wheel paddles. A new transmission-control system and unique algorithms deliver shift performance that rivals the dual-clutch/semi-automatic transmissions found in many supercars - but with the smoothness and refinement that comes with a conventional automatic fitted with a torque converter. The transmission controller analyzes and executes commands 160 times per second. Smaller steps between gears, compared to GM’s six-speed automatic, keep the engine within the sweet spot of the rpm band, making the most of ATS-V’s turbocharged horsepower and torque to optimize performance on and off the track. Additional performance-enhancing features include Performance Algorithm Shift and launch control via the Performance Traction Management system. New, available 16-way-adjustable RECARO performance front seats are the lynchpins for the driving experience, with aggressive, adjustable bolsters that help hold the driver and front passenger in place during high-load cornering.


They’ve also got a luxury-performance feel, trimmed in Mulan leather with sueded microfiber inserts and seatbacks. The rest of the interior features Cadillac’s handcrafted cut-and-sew elements, with decorative stitching and authentic materials, including carbon fiber. Three interior color combinations are offered: Jet Black, Jet Black with Saffron accents and Light Platinum with Jet Black accents. The ATS-V also features a unique version of the 5.7-inch, three-window instrument panel cluster display, with V-Series graphics and distinctive gauge readouts. OnStar 4G LTE connectivity with built-in Wi-Fi hotspot. The Performance Data Recorder is controlled via CUE’s color touch screen and recordings can be reviewed on the screen when the vehicle is parked. The Cadillac ATS-V is a performance car that has the BMW M3 and M4, Mercedes C63 and the Audi RS4 in it's sights. The fit and finish is up to the standard and the on paper performance is on the mark. The price and real world drivability will be the deciding factor as to how many Cadillac will sell.


It’s what your friends will notice when they jump in, and that’s important. With its smoother dual-clutch transmission and ride, it’s in traffic that we expected the Audi to justify its purchase as a daily drive over the AMG. And we weren’t disappointed. The RS3 is a genuinely practical car you can drive every day of the week. Then again, so is the new AMG. And that’s the real surprise here. The previous model was unbearably harsh on suburban roads. Its suspension was designed for smooth European roads and it didn’t have adjustable suspension (like the new car), and, as such, it was best suited for drives straight to a racetrack or to a chiropractor. 6490 RS performance package to gain magnetic ride suspension (along with a host of other features noted at the bottom of the review) to make it a usable daily. The transmission in the old A45 didn’t like going all that slow either, while the new A45’s updated system seems far more composed and willing to be quietly driven around town at low speeds without any jerky notions. As does the S Tronic gearbox in the RS3.


Both cars were set to Comfort mode and had their air conditioning blasting. After about 20 minutes, the AMG’s engine temperature was sitting noticeably above normal (3/4), even though it was hardly getting out of second gear, while the Audi appeared to have no such temperature issues. After a while, the Merc also presented us with tyre pressure errors, as well as a failure in the adaptive headlights. It’s hard to say if these were temperature related, but the Audi had no such problems. Both these problems went away in the AMG after some time. Both cars were filled up with BP Ultimate 98 RON fuel before the city loop and then refilled again after covering identical distances. The Audi used 3.9 litres of fuel while the Mercedes used 3.88L of fuel. Nearly identical in start-stop traffic. Over the bumpy roads heading from Kelvin Grove through the city and back, both cars absorbed the bumps with limited annoyance to passengers. They are surprisingly not all that much firmer than their donor cars.
