2018 Alfa Romeo Stelvio Quadrifoglio vs. 2018 Jeep Grand Cherokee Trackhawk: On-paper sibling rivalry

Pricing was revealed for the 2018 Alfa Romeo Stelvio Quadrifoglio, and with its $81,590 price tag, it's within range of yet another high-performance SUV from Fiat-Chrysler: the 2018 Jeep Grand Cherokee Trackhawk. The Hellcat-powered Jeep is more expensive than the Stelvio at $86,995, but depending on options, the price advantage might go either way. This left us wondering, how similar are these two high-powered SUVs? Besides sharing the same number of words in their very-long names, we took a look at some of their performance specs and put them in the spreadsheet below. As always, if you want to compare either of these with other speedy SUVs, be sure to try out our comparison tools. As far as outright speed, both SUVs are surprisingly close. The Trackhawk is just a bit quicker in a straight line, hitting 60 mph in just 3.5 seconds as opposed to the Alfa's 3.9. The Jeep's 180-mph top speed is also 3-mph quicker than the Alfa. But neither of these differences is especially huge. What makes this interesting is how different the paths each SUV takes to get to its results. The Trackhawk accomplishes the task with pure grunt. It has Dodge's Hellcat supercharged 6.2-liter V8 making 707 horsepower and 645 pound-feet of torque to overcome its hefty 5,363-pound body. The Alfa, on the other hand, makes do with less power and torque, 505 and 443, respectively, from its twin-turbocharged 2.9-liter V6. It has less weight, though. Exactly how much less we're not sure, since Alfa hasn't revealed that number, but a regular Stelvio weighs right around 4,000 pounds, so we would guess the weight is similar, possibly a little more. View 14 Photos The differences in how each SUV achieves its performance should result in pretty different driving characteristics, and probably different buyers. Each SUV's bragging points also indicates this. The Trackhawk boasts an impressive 11.6-second claimed quarter-mile time, something that American muscle car fans everywhere care about. The Alfa brags about how it's the fastest production SUV to lap the Nurburgring, something sure to impress fans of foreign cars and those that value handling over straight-line performance. So really, although these two SUVs have performance similarities, they're also very different, and the right one for you depends on what you value.

B.A.T. Alfa Trinity, some of the world's most famous concept cars, are up for auction

Of the cars that never saw production, there are a handful that nevertheless have had an outsized influence. Among the most famous are the wild Berlinetta Aerodynamica Technica (B.A.T.) concepts commissioned by Alfa Romeo in the mid-1950s. Three B.A.T. Alfas were created by Italy's Bertone design house and were unveiled at succeeding Turin auto shows in 1953, '54, and '55. The cars are now coming up for auction for the first time as a group at RM Sotheby's Contemporary Art Evening Auction in New York on October 28. The first of the trio was B.A.T. 5, which like its successors was built on the Alfa 1900 Sprint production chassis. The goal of the B.A.T. 5 was aerodynamic efficiency, and the car boasted a cD of 0.23. Aiding the cause were covered front wheels, a greenhouse with steeply curved side glass, and twin tail fins. The second concept was B.A.T. 7, from 1954. It has the wildest styling of the trio, with sharply curved tail fins. It also has the lowest drag coefficient, at 0.19. B.A.T. 9, from 1955, was the most production-feasible of the group. It features an Alfa Romeo shield grille at the front and exposed headlights with clear covers. All three are credited to Franco Scaglione, working with Nuccio Bertone. They were seen together for the first time at the 1989 Pebble Beach Concours d'Elegance. They would appear together again at Pebble Beach in 2005 and at Bertone's 80th-anniversary celebration in 1992. The cars were acquired by a single owner sometime after their first Pebble Beach appearance. The ability to acquire all three at once is part of what makes this an extraordinary opportunity. The B.A.T. Alfas are being sold as a single lot and are expected to bring between $14 million and $20 million.

Stellantis aims to eliminate separate inverter, charger to improve EV efficiency

Stellantis has announced that, in collaboration with French battery company Saft and French National Center for Scientific Research, has made significant progress in eliminating two major components of an electric vehicle powertrain: the on-board charger and the power inverter for the motor. The company claims that doing this will allow for better space use in vehicles, as well as improvements in efficiency, cost and reliability of components. As a quick primer, also explained in the below video, the on-board charger and power inverter are sort of translators to get the right current to different parts of the electric powertrain. The on-board charger takes AC power from the grid and converts it to DC to charge the batteries. Then when power goes from the batteries to the electric motor, the power inverter converts that DC power back to AC. These components aren't exactly small. Frequently you'll find them packaged somewhere under the hood. What Stellantis and its cohorts have developed, and have been using on a test vehicle since last summer, are small power inverter boards that can be mounted very closely to the battery packs. They can handle both conversion needs, for charging and discharging, instead of needing two separate devices. The most obvious perk to this is that you can do away with those traditional components and free up more space, either for making smaller vehicles without losing interior volume, or adding space to a vehicle that wouldn't have had it otherwise. There's the additional benefit of reduced weight, something that EVs struggle with. Stellantis also claims improvements in efficiency, reliability, and cost, however, it didn't go into detail as to how this setup would do that exactly. We'll try to get in touch with representatives from Stellantis in order to get more information. We're still a ways out from seeing this technology in production Stellantis vehicles. The company said it aims to apply it to vehicles by the end of the decade. Saft is also looking at using it on stationary battery systems as well. So maybe we'll see it on a 2029 Ram 1500 REV, but for now, we'll be living with traditional chargers and inverters. Related Video: Green Alfa Romeo Chrysler Dodge Fiat RAM Technology Electric
