GM intends to offer semi-autonomous vehicles by 2020

Prepare for a few years of technological saber-rattling, as the world's automakers begin pushing to bring self-driving cars to market. Earlier this week, Nissan announced that it aims to offer autonomous vehicles by 2020, while Google, BMW and several other marks are working on similar efforts.
General Motors is doing things differently, though. Rather than push for a fully autonomous car, it's continuing to refine its semi-autonomous Super Cruise, a product that we tested in April 2012 and that will eventually see use on some Cadillacs before trickling down to the rest of the General Motors family. Super Cruise, which is undergoing testing in the Cadillac SRX, doesn't take complete control out of the driver's hands. Rather, under a very specific set of circumstances on the freeway, it will marry the capabilities of things like lane departure warning and adaptive cruise control to allow the driver to take their hands off the wheel. All of which sounds a lot like the system Mercedes-Benz is launching on the 2014 S-Class.
The system is still in development, according to John Capp, GM's director of electrical controls and active safety technology. Now that that the biggest hurdle, steering control, has been cleared, GM's engineers can focus on things like teaching the system to adapt to differing road conditions and visibility levels. As we reported in 2012, Super Cruise is still befuddled in low-visibility situations or when road markings aren't particularly clear.

Cadillac to recall 20,000 SRX models over wheels that could fall off

A potential issue with the lug nuts on 19,871 units of the 2013 Cadillac SRX in the US and Canada has lead to a recall of the luxury crossover. Those lug nuts that have a Teflon topcoat, identified by their bluish tint, could loosen and cause "creaking, rattling or grinding noises or steering vibrations." In the worst case scenario, a wheel could fall off, but there have been no reports of that happening, nor any reports of accidents or injuries due to the issue.
This is the second recall action on the SRX over the last few months. In March, Cadillac recalled 27,000 SRX models over a transmission programming issue. General Motors will begin notifying customers with the potentially faulty parts on June 3, at which time they can take their vehicles to dealers to have the tires rotated and new nuts installed. A further 7,397 SRXs exported from North America also face the recall action.

2016 Cadillac ATS-V First Drive [w/video]

If you get hot and bothered for hot-rodded sedans and coupes, you probably know that Germans have long dominated that cutthroat scene. For years, the Audi RS/BMW M/Mercedes-AMG triumvirate has ruled the microcosm of grunty, mid-level luxury cars. But a funny thing happened when Cadillac's first V car hit the market in 2004. Since the CTS-V crashed the high horsepower party, German tuning houses started thinking less about the "Daddy's Caddy" stereotypes and more about the next imminent threat – in this case, the inevitable high-horsepower spinoff of the smaller, nimbler Cadillac ATS. The standard ATS' defense against the German triad hasn't been triumphant so far (GM's Michigan plant was idled for three weeks in 2014 due to excess inventory), but the souped-up 2016 Cadillac ATS-V presents a fresh bid to put the Teutonic competition on alert. The ATS-V's flared bodywork and quad exhaust pipes offer bits of visual shock and awe, but significant hardware upgrades back up the go-fast looks. Front and center is a twin-turbocharged, 3.6-liter V6 with reworked internals including a charge-air cooler, titanium connecting rods, and titanium-aluminide turbines. The new engine produces 464 horsepower and 445 pound-feet of torque, up a staggering 262 hp and 173 lb-ft compared to a base, four-cylinder ATS. Those output figures eclipse the BMW M3/M4 (425 hp, 406 lb-ft) and Audi RS5 (450 hp, 317 lb-ft), but lag slightly behind the V8-powered Mercedes-AMG C63 (476 hp, 479 lb-ft), and more so the C63 S (503 hp, 516 lb-ft). The chassis benefits from several structural braces, most notably a shear panel intended to boost front-end stiffness. Extra poundage from the add-ons are minimized through lighter-weight materials – in the case of the shear panel, stamped aluminum. Cadillac says though it intended to make the ATS the quickest car in its segment (stated 0-60 mph times between 3.8 and 3.9 second virtually match the BMW M4 and Mercedes-AMG C63 S' 3.9 figure), the development team says they also focused on subjective qualities like turn-in quickness and steering response. As such, toe links have been replaced with ball joints, mounts have been retuned, and reworked magnetic damping offer greater responsiveness. Six suspension bushings have been stiffened and ten have been completely redesigned, and the Performance Traction Management system that tames beasts like the Corvette Z06 and Camaro ZL1 also helps lay down power in the ATS-V.
