Ward's reveals annual 10 Best Engines list for 2013

Ward's Auto has released its annual 10 Best Engines award winners. The 2013 list covers the full width and breadth of the internal combustion spectrum, from a spate of efficient four-cylinders to the most powerful production V8 on the planet. As always, the entries must be available in a production vehicle in the first quarter of 2013 with an MSRP of less than $55,000. The supercharged 3.0-liter V6 from the Audi S5 held on for the fourth consecutive year, and BMW earned two spots on the list with its turbo 2.0-liter four-cylinder and turbo 3.0-liter inline-six.
Ford pulled in two awards for its 2.0-liter EcoBoost four-cylinder and and the supercharged 5.8-liter V8 from the Shelby GT500. Honda matched BMW and Ford with two wins of its own. Wards awarded the 2.4-liter four-cylinder from the Honda Accord Sport as well as the 3.5-liter V6 from the Honda Accord. Chrysler, General Motors and Subaru each garnered a spot on the list as well for the 3.6-liter V6 in the Ram 1500, the turbo 2.0-liter four-cylinder in the Cadillac ATS and the 2.0-liter four-cylinder the Subaru BRZ, respectively.

Confident new Cadillac marketing boss ready to take on Tesla, BMW

When there's a former BMW executive heading Cadillac's efforts to boost sales of its only plug-in, it's a pretty safe guess that the marketing emphasis won't be on environmental friendliness and tree-hugging tendencies. The General Motors luxury brand has appointed ex-Bimmer executive Uwe Ellinghaus to be its marketing chief late last year, and the German-born Ellinghaus is now saying that he's targeting potential customers of Tesla Motors, in addition to BMW, for potential growth in sales of the Cadillac ELR extended-range plug-in. Appointed to Cadillac's head of marketing last November, Ellinghaus recently told Advertising Age that GM needs to highlight the Cadillac's looks and performance. He complimented Tesla for putting more emphasis on those attributes in the Model S than on its lack of emissions or lack of refueling costs (but Tesla hasn't shied away from highlighting the EV's savings). Ellinghaus says that trying to gear advertising "for people who are tree-huggers and green-wash an entire brand" won't be successful. You don't say. So far, the ELR hasn't made much of a dent in US car sales. Through May, Cadillac, which spent about $280 million on all of its US marketing last year, sold 293 units, whereas Tesla had been approaching the 11,000-unit figure for the Model S. With that in mind, Cadillac may be working on a sportier version of the ELR, as spy shots of a test vehicle from May revealed larger brakes and wheels.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
