2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

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 pins hopes on 2016 R18 Le Mans prototype

Down but not out, Audi is carrying forward its endurance racing program with the new R18 you see here. Unveiled on Saturday at the Audi Sport Finale end-of-season event in Munich, the new LMP1 is billed as the company's its most powerful and efficient race car yet. And it has been thoroughly redesigned to bring the Four Ring brand back to the winner's circle. Though technical details remain a closely guarded secret, Audi says that the latest evolution of the R18 (now apparently labeled sans the E-Tron Quattro) benefits from revised aero, lightweight construction, and "a modified hybrid system with lithium-ion batteries for energy storage, plus an efficiency-optimized TDI engine." That spells the end of the mechanical fly-wheel setup of the previous version, but sticks to the diesel fuel that Audi has championed instead of the gasoline favored by rivals Porsche and Toyota. With all its revisions, Ingolstadt undoubtedly hopes this latest version will perform better than the last. This past season was the worst Audi has endured since 2009. Its sister company Porsche beat it to both the drivers' and manufacturers' titles in the FIA World Endurance Championship and to the winner's circle at the 24 Hours of Le Mans. That marked the second straight year of defeat in the championship, following Toyota's domination last season, and marked only the third time Audi was defeated at Le Mans since 2000, following Bentley's win in '03 and Peugeot's in '09. In order to avoid costly inter-agency arms race, Audi and Porsche have agreed to each field two entries instead of three in both the championship and the headline race in Western France. Audi has yet to confirm its driver lineup, but Porsche has revealed its lineup consisting of defending champions Timo Bernhard, Brendon Hartley, and Mark Webber in one car, and Romain Dumas, Neel Jani, and Marc Lieb in the other. That leaves out the Le Mans-winning trio of Nico Hulkenberg, Nick Tandy, and Earl Bamber, with the former already counted out due to an F1 conflict. More powerful and efficient than ever before: Audi R18 celebrates world premiere in Munich - New hybrid race car for the 2016 Le Mans 24 Hours - Unchanged driver line-up in the DTM - High demand for new Audi R8 LMS GT3 sports car The brand with the four rings will be entering the 2016 motorsport season with the most powerful and efficient race car Audi has ever built.
