EcoCar2 is on the hunt for a better, cleaner Chevy Malibu [w/video]

The students spent three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. Not far from the building where General Motors once invented the Chevy Volt, a dozen or so college students are standing on the blacktop alongside a test track, watching a professional driver push the limits of a plug-in hybrid car they've built that's far more radical. These students, from Colorado State University, have spent the past three years transforming an ordinary Chevy Malibu into a revolutionary vehicle. At first glance, it still looks like a regular sedan. But under the hood, they've installed a hybrid powertrain that contains both hydrogen and electric power sources. Even by the standards of the Department of Energy competition they're participating in, it's an outlier. That's exactly what they had in mind. "We didn't want to come here and tell them how to build a better Volt," said Tom Bradley, faculty adviser for the Colorado State team. "They already know how to do that. We can tell them how to think about these possibilities in a whole new way." After three years of work, it all comes down to this. The Colorado State team was one of 15 that came to GM's Milford Proving Grounds last week for the final stretch of the EcoCar2 competition, which challenges regular college students who have no automotive experience to do nothing less than reinvent the American car. The teams have come from across North America, and include schools like Ohio State and Virginia Tech that have a long history of participating in similar competitions, and schools like the University of Washington and Embry-Riddle Aeronautical University that are here for the first time. After three years of work, it all comes down to this. The teams have operated 24 hours a day for almost two weeks here at the Proving Grounds, running a gamut of tests that include a 310-point safety inspection, emissions and energy-consumption tests and road tests, in which professional GM drivers ensure they're road worthy. The winning team will be announced tonight in Washington D.C. Revolutionary cars, ordinary package While other green-car competitions encourage extreme designs, this one comes with a somewhat constraining twist: Yes, students must improve fuel economy and reduce emissions, but in the end, they still have to have a car that would appeal to mainstream customers. In practical terms, that means they must keep conveniences like air conditioning and trunk space.

GM raises 2023 guidance on strong sales, higher profits

General Motors beat first-quarter profit estimates and raised its full-year earnings and cash-flow guidance after vehicle demand at the start of the year surpassed expectations. Its shares rose in premarket trading. GM made $2.21 a share in adjusted profit in the first quarter, compared to a consensus forecast of $1.72 a share. Revenue rose 11% to $39.99 billion, it said Tuesday, which was more than the $39.24 billion analysts expected. The stronger results stem from rising sales in the US, even in the face of higher interest rates and inflation. GM executives said demand was strong enough to revise 2023 guidance upward, boosting profit estimates for the year by $500 million to between $11 billion and $13 billion. “We did it with strong production and inventory discipline and consistent pricing,” GM Chief Financial Officer Paul Jacobson said on a call with journalists. “All in all, weÂ’re feeling confident about 2023.” The Detroit automaker raised per-share full-year guidance to between $6.35 and $7.35, up from $6 to $7 a share, and said free cash flow would also increase by $500 million to a range of $5.5 billion to $7.5 billion.  GMÂ’s shares pared a gain of as much as 4.4% before the start of regular trading Tuesday, rising 3.5% to $35.50 as of 6:55 a.m. in New York. The stock was up 1.9% for the year as of the close on Monday.  North American Strength The automakerÂ’s sales were particularly strong in North America, where first-quarter earnings rose before interest and taxes rose to $3.6 billion. Vehicle sales rose 18% to 707,000 in the region. Jacobson said the company originally expected to sell 15 million vehicles in the US this year, slightly less than the 15.5 million annualized rate automakers foresaw in the first quarter. North American demand was enough to offset a weak performance in China, GMÂ’s second-largest market. The automaker continues to struggle in the country, where its vehicle sales fell 25% to 462,000 vehicles in the quarter. Profits from its joint ventures in the market slumped 65% to $83 million.  The market has struggled overall in the wake of Covid-19 restrictions and foreign automakers have had to overcome a growing preference for Chinese brands by competing on price, squeezing profit margins. The situation in China probably wonÂ’t significantly improve until the second half of the year, according to Jacobson. GM remains on target to sell 150,000 electric vehicles this year, the CFO said.

Dodge Challenger SRT Hellcat vs. Chevrolet Camaro ZL1 in latest Head 2 Head

"Olympian" is one of the terms we use to signify the greatest height, the seat of the gods. Yet Mt. Olympus is the second-highest peak in the Balkans ranges, overshadowed by the crest at Musala in Bulgaria's Rila mountains. Both great heights, but one is a little higher. That's how we get the Olympian Chevy Camaro ZL1 pitched at the Musalic Dodge Challenger SRT Hellcat in Motor Trend's latest episode of Head 2 Head. The side-by-side spec sheet is filled with farcical numbers. For the ZL1, that's a 6.2-liter V8 with 580 horsepower, 556 pound-feet of torque, a 4,051-pound curb weight, 0-to-60 miles per hour in 3.9 seconds, a quarter-mile time of 12.2 seconds and a base price of just $57,800. Opposing that, the Hellcat wrings out its 6.2-liter V8 for 707 hp, 650 lb-ft of torque, weighs 4,449 pounds, does the quarter in 11.7 seconds and has a base price of just $60,990. Except in the case of the Hellcat, when Motor Trend put it on the dyno the machine spit out a reading of 672 hp and 606 lb-ft at the wheels. If there's a 10-percent driveline loss through those beefed-up internals and heavy-duty eight-speed transmission, that means the Hellcat is actually rated at about 750 horsepower and 700 lb-ft. But once they get put on a closed-off strip of coast road in Northern California, there are only a few strands of hair between their respective performances. That's not the case for they sensations provide; host Jonny Lieberman calls one of them, "One of the most incredible cars ever made," and says, "It changes everything." Watch the video above to see who got the verdict and how. Related Video:
