2015 Chevrolet SS Review [w/video]

The Chevrolet SS is one of the best cars no one's buying. It's a Bowtie-badged version of the Australian Holden Commodore with a 6.2-liter LS3 V8 under the hood. It's got a six-speed manual transmission, General Motors' sophisticated Magnetic Ride Control suspension, and rear-wheel drive. It's a fullsize sedan that comes with every possible amenity you could want. And it's less than $50,000. Chevrolet sold 2,479 SS sedans in 2014. That means it was outsold by every other vehicle the automaker offers, even the police fleet-only Caprice. (I'm only talking about cars that were on sale for the full 2014 calendar year, of course.) The aforementioned manual transmission and MRC suspension were added for 2015, but it's not clear if that's helping. The SS is down 7.7 percent through June of this year, compared to 2014's numbers. But hey, at least it's finally outselling the Caprice. What a damn shame. Granted, GM only planned to sell a few thousand of these each year, but as enthusiasts, this a car we should be gobbling up. It's the closest we'll get to a four-door Corvette, and with the 2015 model year updates, that statement is more true than ever. People often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Aside from the manual gearbox and magnetorheological suspension, the SS is largely unchanged through its year and a half of sales. But that's no bad thing – we were thoroughly impressed with the SS when we first tested it at the end of 2013. Outside, the SS looks the same, which is a bummer. It is not an attractive car, and the chrome brightwork on the side vents and wheels doesn't help. That said, the sedate styling puts it under the radar – more so than competitors like a Dodge Charger 392, anyway. But maybe it's too under the radar. Even in the new, "Some Like It Hot Red" color (yes, really), photographer Drew Phillips reports that people often mistook the SS for a Malibu. "Is that a rental car?" Yikes. Exterior styling is our only gripe with the SS. Moving inside, there's a lot to like. This is easily one of Chevy's nicest, well thought-out interiors (thanks, Holden), with premium materials and tons of equipment. The Chevy MyLink infotainment system carries over, and now features 4G LTE and wifi connectivity. The touchscreen is a bit slow to respond, but otherwise, it's bright, well organized, and packed with functionality. This is easily one of Chevy's nicest, well thought-out interiors.

Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
