'84 MotorWeek Cherokee, Bronco and Blazer comparison indulges your SUV nostalgia

These days, truck-based, full-frame SUVs are somewhat of a rarity on the auto landscape due to the rapid rise in popularity of easier-driving, car-based crossovers. Although, without the gradually building popularity of these chunky, high-riding vehicles decades ago, it's unlikely that America's roads would be filled with so many CUVs today. In its latest dig into the archives, MotorWeek has found a 1984 comparison test of a trio of these early Sport Utility Wagons, as long-time host John Davis called them, that helped get acceptance of this segment going. This is a red, white and blue test of the SUVs from American automakers at the time and pits the Chevrolet Blazer, Ford Bronco and Jeep Cherokee (specifically in Wagoneer guise) against each other. Driving manners and interior usability are considered in the evaluation, but Motorweek actually takes these vehicles off road, too. Among the bigger revelations is the improvement in on-road ability in the past 30 years. While specific 0-60 times aren't given, all three models take around 10 seconds just to get to around 50 miles per hour in the 500-feet on-ramp acceleration test. Check out this clip to see just how far this segment has progressed in the past three decades or just get a blast of nostalgia from these now vintage models.

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.

Weekly Recap: Lamborghini to build SUV

Finally, Lamborghini will build a sport utility vehicle. The Italian supercar maker confirmed this week that it will launch a luxury SUV in 2018. It will be built at Lamborghini's soon-to-expand factory in Sant'Agata Bolognese in Italy, and will double the company's current sales volume. Lamborghini did not announce a name for the vehicle or other details, but noted a concept version, the Urus, was displayed at the Beijing motor show in 2012. It will be sold around the world, but it's expected to be a critical offering in the United States, China, and the Middle East. The automaker projects the SUV will sell about 3,000 units per year, and it will be the third product in Lamborghini's portfolio. It currently sells the Huracan and Aventador supercars. "The introduction of a third model line endorses the stable and sustainable growth of the company and signifies for us the beginning of a new era," Lamborghini chief executive Stephan Winkelmann said in a statement. The project is also a boon for Italy, which will get 500 new jobs in the Emilia Romagna region as Lamborghini's factory will nearly double in size. Ian Fletcher, principal analyst for IHS Automotive, said the SUV will position Lamborghini for future growth. "It could well also bring new customers to the brand [who] may find the dramatic styling of Lamborghini products appealing, but find its typical sports cars restrictive," he said. "If it is a success, the SUV could be a catalyst to Lamborghini broadening its portfolio further." OTHER NEWS & NOTES GM invests in Chevy Camaro factory General Motors is investing $175 million to upgrade its factory in Lansing, MI, to build the 2016 Chevy Camaro. The investment will pay for new tooling and equipment. The improvements include three new paint systems and two new robotic framers. GM will add a second shift at the factory to build the Camaro, resulting in 500 jobs. The automaker had dropped the plant to one shift last year amid slow sales for its products, the Cadillac ATS and CTS. GM is spending $5.4 billion over the next three years to upgrade its US facilities. Last week, GM announced plans to spend $439 million to build a new paint shop for the Chevy Corvette. While the Camaro and Corvette plant improvements are intriguing to enthusiasts, GM also confirmed this week that it is investing $1.2 billion in its Fort Wayne (IN) factory that builds trucks.
