2018 Buick Regal TourX vs. wagon competitors: How it compares on paper

To the great joy of auto enthusiasts nationwide, wagons are back! Well, at least there's a few more of them. The latest is the 2018 Buick Regal TourX, which we just had our first drive of and found to actually be quite good with pleasant handling, solid power and plenty of space. But, how does the TourX compare to other cladded wagons? Well, let's dive into the specs and fire up the ol' spreadsheet maker for Buick Regal TourX vs Subaru Outback vs Audi A4 Allroad vs VW Alltrack vs Volvo V60 Cross Country. True, some are from mainstream brands and others are from luxury marques, but Buick straddles both realms, so it's appropriate to look at them all. Of course, there's more to these cars than just the numbers, but they're still important, and in the case of this class of crossover-aping wagons, can vary more than you'd expect. So check out the specs in the chart below, which are followed by more analysis and photos of each. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines and Transmissions When comparing powertrains, the Buick is far-and-away the winner as far as torque is concerned, and is in a nearly three-way tie for horsepower. Its 295 pound-feet of torque is 22 lb-ft more twist than the next-most-grunty Audi A4 Allroad. And in regards to power, the Buick's 250-horsepower engine is only down 6 hp to the most-powerful Subaru and its optional naturally aspirated flat-six, and just 2 hp less than the Audi. At the bottom of the pack is the Subaru Outback with the standard naturally aspirated flat-four, which only makes 174 hp and 174 lb-ft of torque. That may not seem too bad compared with the VW Golf Alltrack, which only makes 170 hp and 199 lb-ft of torque, but the VW is much lighter by between 200 and 300 pounds. Transmission-wise, there's quite a bit of variation in the group. The Regal TourX and the Volvo V60 Cross Country rely on eight-speed automatics, all Outbacks use CVTs, and the Alltrack and Allroad have dual-clutch automated manual transmissions with six and seven gears, respectively. But for people that want to shift for themselves, the only option is the Volkswagen, which offers a traditional six-speed manual transmission on the Golf Alltrack. Cargo and Interior Space One of the main reasons to buy a wagon is for the body style's large cargo capacity. And for the most space for things and stuff, you'll want to check out the Subaru and the Buick.

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.

Audi A4 preps to go Allroad

Audi recently unveiled the lighter, larger, and sleeker 2017 A4, but the sedan is just the beginning. We know that A4 Avant and Allroad wagon versions are on the way too. Only the Allroad, however, is destined for these shores. These spy shots provide an early idea of what to expect for American buyers who prefer a longer roof and more room to haul in the back. A few key details distinguish this Allroad from the standard Avant, including the elevated ride height. Also, look carefully at the front three-quarters shot, and you can also pick out the more pronounced fender flares. Audi's designers made slight adjustments to the air dam, especially below the headlights, and there are some smaller tweaks to the rear bumper, as well. The Allroad's debut is expected to be staggered from the sedan and Avant versions, and the company obviously isn't talking about power yet. The only powertrains divulged for the 2017 A4 in the US are either a revised 2.0-liter TFSI or a 2.0-liter TDI diesel. Regardless of engine, all-wheel drive would certainly be standard to fit the more rugged version's styling. Related Video:
