Cadillac could base its entry-level sedan on the Chevy Cruze [UPDATE]

UPDATE: Cadillac spokesperson Donny Nordlicht tells Autoblog , "The post speculating on a future Cadillac model derived from the Chevrolet Cruze is completely false." Premium automakers Mercedes-Benz and Audi have seen plenty of success with new small front-drive-based sedans. The CLA-Class had its best January ever this year, while Audi moved more of its new A3 in 2015 than its predecessor sold in 2005 through 2010 combined. The fact that Cadillac wants a piece of that pie is no surprise, then. There's a new rumor that GM's luxury brand could launch its own compact – possibly called CT2 – to battle the Germans. Cadillac, a brand that's pushed hard to rebuild its rear-drive reputation, could develop a new entry-level model based on the front-wheel-drive 2016 Chevrolet Cruze's D2XX platform. Go ahead and make your Cimarron jokes. Sources are telling GM Inside News that a Cadillac built on the Delta platform would ditch the Cruze's turbocharged 1.4-liter four-cylinder for a 1.5-liter turbo in base models. General Motors' well received 2.0-liter turbo four would serve in higher-end models. According to GMIN, the Delta-based Cadillac would likely command a $6,000 to $9,000 premium over the Cruze, so figure $23,000 to $26,000 on the low end to $30,000 to $33,000 for something at the top of the range. As much as we dislike the kind of badge engineering that brought us the Cavalier-based Cadillac Cimarron in the '80s, the company has done an admirable job of distinguishing vehicles on shared platforms lately. A Delta-platform Cadillac would at least have a good basis – the new Cruze is surprisingly comfy. That said, we question GM's rationale if this rumor is indeed true. Put simply, Cadillac needs another sedan like I need another student loan payment. The company has four sedans, three of which overlap two segments, and none of which are selling very well. That's not because they're bad, but because customers want crossovers, of which Caddy has but one – the new XT5. Spending the time and money to add a fifth sedan to the mix when the company desperately needs to flesh out its CUV range would be a tremendous mistake. As much as we hate to say it, if Cadillac really wants to add a small, entry-level car to its range, it'd better be a crossover. Related Video:

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.

Impala SS vs. Marauder: Recalling Detroit’s muscle sedans 

Impala SS vs. Marauder — it was comparo that only really happened in theory. ChevyÂ’s muscle sedan ran from 1994-96, while MercuryÂ’s answer arrived in 2003 and only lasted until 2004. TheyÂ’re linked inextricably, as there were few options for powerful American sedans during that milquetoast period for enthusiasts. The debate was reignited recently among Autoblog editors when a pristine 1996 Chevy Impala SS with just 2,173 miles on the odometer hit the market on Bring a Trailer. Most of the staff favored the Impala for its sinister looks and said that it lived up to its billing as a legit muscle car. Nearly two-thirds of you agree. We ran an unscientific Twitter poll that generated 851 votes, 63.9 percent of which backed the Impala. Muscle sedans, take your pick: — Greg Migliore (@GregMigliore) April 14, 2020 Then and now enthusiasts felt the Impala was a more complete execution with guts. The Marauder, despite coming along later, felt more hacked together, according to prevailing sentiments. Why? On purpose and on paper theyÂ’re similar. The ImpalaÂ’s 5.7-liter LT1 V8 making 260 horsepower and 330 pound-feet of torque was impressive for a two-ton sedan in the mid-Â’90s. The Marauder was actually more powerful — its 4.6-liter V8 was rated at 302 hp and 318 lb-ft. The ImpalaÂ’s engine was also used in the C4 Corvette. The MarauderÂ’s mill was shared with the Mustang Mach 1. You can see why they resonated so deeply with Boomers longing for a bygone era and also captured the attention of coming-of-age Gen Xers. Car and DriverÂ’s staff gave the Marauder a lukewarm review back in ‘03, citing its solid handling and features, yet knocking the sedan for being slow off the line. In a Hemmings article appropriately called “Autopsy” from 2004, the ImpalaÂ’s stronger low-end torque and smooth shifting transmission earned praise, separating it from the more sluggish Mercury. All of this was captured in the carsÂ’ acceleration times, highlighting metrically the differences in their character. The Impala hit 60 miles per hour in 6.5 seconds, while the Marauder was a half-second slower, according to C/D testing. Other sites have them closer together, which reinforces the premise it really was the little things that separated these muscle cars. Both made the most of their genetics, riding on ancient platforms (FordÂ’s Panther and General MotorsÂ’ B-body) that preceded these cars by decades. Both had iconic names.
