GM Donates 2014 CTS Vsport to Benefit STEM Education

First production Cadillac model to be auctioned with proceeds to SAE Foundation

WARREN, Mich. – Mary Barra, General Motors senior vice president, Global Product Development, was honored Wednesday evening with the Society of Automotive Engineering Foundation's 2013 Industry Leadership Award. Barra is the first woman recipient in the 25-year history of the award.

Barra said GM would donate the first production 2014 Cadillac CTS Vsport, including a performance driving school package, to the SAE Foundation.

The CTS Vsport will be the first Cadillac model to offer an eight-speed automatic transmission. The car is built on the high-performance award-winning ATS architecture and is equipped with a Twin-Turbo V-6.

A live auction will be conducted by Barrett-Jackson later this year, and proceeds will be provided to the SAE Foundation for its science, technology, engineering and mathematics student outreach programs.

"The SAE Foundation's STEM educational programs are vital to ensuring we ignite the passion for math and science in young students who will be the future leaders of the automobile industry," said Barra. "At a recent SAE a World in Motion third-grade skimmer project I was especially gratified to see students having so much fun applying key principles of math and science. So it is fitting to support SAE's programs by donating a vehicle that embodies what is possible when ingenuity meets engineering excellence."

GM has long sponsored the SAE Foundation's STEM outreach programs. In addition to financial support from the GM Foundation, GM provides more than 1,500 mentors and volunteers who help reach nearly 85,000 students participating in SAE's World in Motion K-12 programs.

"We need to ensure that the next generation of professionals has the skills and education necessary to compete on a global basis. SAE's programs integrate physical science basics with team-based learning – and show young people that math and science is a viable career choice," said John Calabrese, GM vice president, Global Vehicle Engineering.

"By investing in programs like SAE's a World in Motion, we help get students engaged at an early age and keep them interested."

Nissan recalling 841k vehicles overseas for steering wheel trouble

A possible issue with a steering wheel bolt in the Nissan Micra (shown) and Cube from the 2002 to 2006 model years has Nissan recalling roughly 841,000 units on four continents, as well as Oceania and the Middle East. On the affected cars, the bolt may not have been tightened properly, which could lead to a loss of steering in a worst-case scenario. According toReuters, there haven't been any reports of accidents or injuries due to the fault, however.

The Micras affected were built in the UK and Japan, the Cubes in Japan. Nissan has yet to say when the recall will begin, but when it does, owners can take their cars to dealers for repairs; the bolt with either be tightened or, if necessary, a new steering wheel installed.

2014 Chevy Corvette Stingray horsepower and torque figures leaked?

Despite the fact that General Motors has already pulled the wraps off of the highly anticipated Chevrolet C7 Corvette Stingray – in both coupe and convertible forms – there's still a lot we don't know about The General's new halo car. When it first launched, GM stated that the 'Vette's new 6.2-liter LT1 V8 would put out an estimated 450 horsepower and 450 pound-feet of torque. But some PDF scans found by the folks at the Corvette7 forum site show that the Stingray coupe might actually throw down 455 hp and 460 lb-ft – increases of 5 hp and 10 lb-ft over the original numbers, and gains of 25 hp and 36 lb-ft versus the current car's 6.2-liter LS3 V8.

If these PDF scans are to be believed, it looks like only the coupe will benefit from this slightly more powerful setup, as a similar spec list for the Corvette Stingray Convertible states that the droptop will make 450 hp and 450 lb-ft – spot on with the original estimates. Official fuel economy numbers are still unknown, though GM has previously stated that the 'Vette is "expected to improve" upon the current car's EPA highway rating of 26 miles per gallon.

We expect the officially official numbers to be revealed later this year, closer to the Corvette's launch. Head over to Corvette7 to read more, and check out the PDF scans for yourself in the gallery below.

2014 Chevrolet Cruze Diesel

Volkswagen has gotten pretty comfortable hogging the – admittedly small – non-premium diesel car market in the US. With Golf and Jetta, the German automaker has been the one and only choice for those interested in the torquey, high-mpg merits of turbocharged diesel power.

However, US customers seem to be growing more interested in the technology that has been the primary mode of propulsion in most of Europe for many years now. Mazda is quite close to bringing its Skyactiv-D diesel engines to our shores, and Chevrolet has finally maneuvered to repurpose its European 2.0-liter turbo-diesel engine for US specification, which means it's cleaner here than overseas.

The first application of this rather impressive diesel engine is in the compact Chevy Cruze, which I spent a recent morning testing out. General Motors as a whole has high expectations for its new TDI-buster. Here's why:

Driving Notes:

• Since the Cruze Diesel has the Jetta TDI squarely in its targeting computer, allow me to start off with a tale of the tape for the two engines. Chevy's diesel displaces 2.0-liters, makes 151 horsepower and 264 pound-feet of torque (with an overboost mode that allows for brief moments of 280 lb-ft), consumes an EPA-estimated 46 miles per gallon on the highway and 27 in the city, and launches the Cruze from 0-60 miles per hour in 8.6 seconds. The Jetta TDI has a similar 2.0T diesel, with 140 hp and 236 lb-ft of torque, is rated at 42 mpg highway and 30 mpg city, and will 'sprint' to 60 mph in 8.7 seconds (with DSG transmission). Chevy only offers a six-speed automatic with the Cruze Diesel, while VW will sell you a six-speed manual or a six-speed dual clutch gearbox.
• Turn the key on the Cruze Diesel and, if the windows are down, you'll hear a rather loud, clattering noise from the engine bay, at idle. The sound isn't worse than other small diesels we've heard, but it is surprising since the sealed-cabin quiet of the Cruze is remarkably high. With loads of attention paid to refinement at speed, the Cruze is all but silent on the highway (there's some wind noise), and the exhaust note only intrudes when approaching the 5,000-rpm redline.
• Power from the diesel engine feels super strong from even very low revs, as is expected, I guess. Peak torque is available at just 2,600 rpm, and a full 250 lb-ft can be had over the broad expanse between 1,750 and 3,000 rpm. Much like the Jetta, the Cruze isn't fast from a dead stop, but the acceleration from middle to high highway speeds (60 to 80 mph, let's say), is fantastic.
• I drove or rode for about 90 miles in total over this very short preview program, but early returns on the fuel economy are good. Cruising at around 75 mph on the highway saw the fuel econ meter settle at around 44 mpg after just 15 miles, so my guess would be that the estimated 46 mpg or better is easily within reach. (We know from experience that more than 50 mpg is was possible with our long-term Jetta TDI.) On the second leg of our trip, which started on country roads and headed back to the highway, I saw roughly 30 mpg after starting really aggressively and then settling into speed-limit driving around 40 mph. Again, with an EPA City rating of 27 mpg, I'd guess that the Cruze is set to have better real-world numbers than its window sticker would suggest.
• The overall ride characteristic of the Cruze matches its noiseless cabin, insofar as the car really smoothed out the road underneath me. I drove over some pretty broken down Michigan backroads in the car, and found that only the worst potholes and pavement breaks filtered through the softish suspension setup.
• That softness in the suspension, combined with low rolling resistance tires, meant that when I did try to corner aggressively in the Cruze I was met with a lot of vertical motion from the corners and loss of grip. The small Chevy does have a nicely balanced front-wheel-drive chassis for the most part, but handling is only satisfying up to a warmed-up point.
• In all, I think that the new Cruze Diesel presents an interesting counterpoint and alternative to the Jetta TDI, without being dramatically better or worse than the default diesel standard bearer. You can buy the Jetta for a cheaper starting price at $23,055 with no options, but Chevy has, for better or worse, piled on a good amount of kit to its $24,885 basic Cruze Diesel. That sum (plus another $810 for destination) will get you remote keyless entry and start, heated front leather seating, MyLink with Bluetooth connectivity and a touchscreen interface, 17-inch aluminum wheels and more. I think that the 2LT package ($380 for power, heated mirrors, rearview camera, etc), the $795 navigation option and the $100 option for a heated oil pan (great for cold starts) are really good values, too.
• What you get with the Jetta is an ever-so-slightly sportier package (thanks mostly to the better manual/DSG transmission options) and a little bit more brand prestige in the minds of most buyers. This diesel Cruze will need some time to penetrate the land of enthusiasts and diesel geeks, I'm guessing, but it's a fine sedan in its own right, and worth at least a look from even the most ardent TDI supporter.

Millionth Jeep Wrangler JK to roll off line this morning

According to a report on the Chrysler Communications Facebook page and one fairly grainy image of the production line, at around 11:00AM Eastern this morning, the one-millionth Jeep Wrangler JK will roll out of the company's Toledo assembly plant.

The third-generation or "JK" Jeep Wrangler has been around since the 2007 model year, and has obviously been more popular than ever. With a greater than ever number of trim levels, two-door and four-door Unlimited models and hardy off-roading Rubicon packages, the JK offers more to choose from than ever for those looking for something in a traditional Jeep. In fact, with the modern 3.6-liter Pentastar V6 powering it, the 2012 model year saw more than 140k Wrangers sold here in the US; the best-ever figure for the model.

With a model refresh due out for the Wrangler in 2015 (along with the likely addition of a diesel engine option), we expect that sales will continue to roll right along, too.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.

While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed – a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero – there's always been some Mythbusters-level contention about such things –but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

GMC Pickups 101: Busting Myths of Truck Aerodynamics

2014 Sierra gains fuel economy, quietness from time in wind tunnel

DETROIT – The all-new 2014 Sierra full-size pickup truck spent more development time in a wind tunnel than any GMC pickup before it, resulting in design changes that benefit both fuel efficiency and interior quietness.

To achieve improved airflow, aerodynamic engineers like Diane Bloch examined every millimeter of the truck to find areas of improvement, debunking some popular myths along the way.

To study the way air passes over, under and around the Sierra, engineers used General Motors' state-of-the-art Aerodynamics Lab, a 750-foot-long tunnel through which a 43-foot-diameter fan powered by a DC electric motor with the equivalent of 4,500 horsepower can generate winds of up to 138 mph. Aerodynamic advancement is one reason why the 2014 Sierra will be the most fuel-efficient V-8 pickup on the market.

"We can't stop air; we can only guide it through the path of least resistance. It's like electricity, without the shock," said Bloch, GM aerodynamic performance engineer. "The biggest misconception is that it's all about single components. But a certain side mirror design doesn't create a certain amount of drag, its interaction with the rest of the vehicle does."

For example, a new air dam below the 2014 Sierra's front bumper successfully reduces drag because it directs air toward the ground and away from the truck's rough underbody. And Sierra's ducted flow path between the grille and radiator prevents air from swirling inside the truck's front cavities.

Even the top of the Sierra's tailgate and the center high-mounted stop light are optimized to guide air cleanly around the truck. And because Bloch's team detected unwanted airflow between the cab and bed, new sealing has been added.

"We discovered that in the computational analysis we perform," said Bloch. "The most harmful air between the cab and bed was coming over the cab and down through the gap, so we paid the most attention to that specific area."

The pickup market has a great number of available aftermarket accessories, and Bloch says those have varying impact on aerodynamics. Add-ons like bug deflectors on the hood, wider tires or aftermarket bumpers can raise the drag coefficient, which is the measure of how air pushes on a vehicle as it moves down the road. The result: added noise and increased fuel consumption.

A long-disputed topic among truck owners is whether a tailgate raised or lowered is better for aerodynamics, but Bloch says a tailgate in the up position is more aerodynamically efficient. As air flows over the truck, it falls over the cab and pushes forward on the rear of the truck. With the tailgate down, the benefits of that airflow are diminished.

"Replacing the tailgate with an aftermarket net is worse than having no tailgate at all," Bloch said. "Imagine dragging a solid object and a fishing net through water. The net is going to require more muscle."

So what accessories can truck owners add to help aerodynamics? Tonneau covers for the bed help smooth airflow over the truck, and Bloch says soft covers are more beneficial than hard covers because they form to how the air wants to flow. Running boards can also help air flow smoothly down the truck's sides.

"Round, tube-style running boards can provide a minor improvement to the truck's drag coefficient," said Bloch, "Fully integrated, flush-mount running boards are even better."

GMC has manufactured trucks since 1902, and is one of the industry's healthiest brands. Innovation and engineering excellence is built into all GMC vehicles and the brand is evolving to offer more fuel-efficient trucks and crossovers, including the Terrain small SUV and Acadia crossover. The 2014 Sierra half-ton pickup boasts all-new powertrains and design, and the Sierra Heavy Duty pickups are the most capable and powerful trucks ever built by GMC. Every retail GMC model, including Yukon and Yukon XL full-size SUVs, is now available in Denali luxury trim.

BMW 2 Series caught uncovered during shoot

Before we know it, the BMW 1 Series will be no more in the United States. Well, sort of. The current six-year-old coupe and convertible will be replaced by the fancy new 2 Series you see here, spotted completely uncovered during a photo shoot, with the 1 Series nomenclature being reserved for the hatchback and GT models that might not ever make it Stateside.

The roofline of the new 2 Series doesn't appear to have to changed all that much from the current 1 Series coupe, but the front and rear fascias have indeed been smoothed out. (Truth time: As much as your author adores the 1 Series, he's always found its rear end to be, well, weird.) It looks good, seen here in M235i guise, with large wheels, slimmer headlamps and large air intakes on either side of the front fascia.

The 2 Series is expected to come to the States, likely in M235i and 228i variants, though rumors suggest that we won't get a non-M 235i model. The M235i is expected to be powered by the N55 turbocharged inline-six that we currently enjoy in the 335i sedan, producing something like 320 horsepower. The 228i, unsurprisingly, should use the 2.0-liter turbo-four from the 328i, making around 240 hp. Both engines will almost certainly employ eight-speed automatic transmissions and six-speed manuals.

Look for the new coupe to make its official debut in the coming months, with production scheduled to start in November.
