Meet the first of four Audi A4s coming to our long-term fleet

Yes, you read that right, this is the first of a quartet of A4s we'll be looking at over the course of the year. We're kicking things off with an Audi A4 Premium Plus sedan, and we'll be looking at other iterations of the A4 line later on: the A4 Prestige, Allroad, and S4. What we hope to do is provide you with a thorough examination of each variation, and hopefully give you some guidance on what's worthwhile and what isn't. But first, let's introduce you to the A4 Premium Plus. What we got The A4 Premium Plus is the middle child of the standard A4 line, fitting between the entry-level Premium and the top level Prestige. Stepping up to the Premium Plus adds 18-inch alloy wheels, LED headlights, an S Line body kit, Bang & Olufsen sound system, parking sensors, aluminum window trim, and heated power seats with memory. The model we received from Audi has a number of upgrades that bring it quite close to the Prestige trim level. Most notable is the Technology package, which adds the Audi Virtual Cockpit instrument panel, which replaces the physical gauges with a big LCD screen. It also comes with rear cross traffic alert. A First Edition package was added, too, which adds cooled sport seats, a three-spoke steering wheel, and unique wheels and aluminum interior trim. Our favorite part, is the sport package, which adds sportier suspension, a black headliner, and the aforementioned sport seats. What we skipped Really, we didn't skip much here – this particular A4 Premium Plus is pretty loaded. The only packages not included were the Cold Weather package, which includes heated rear seats and steering wheel, and wheel and tire options. The heated steering wheel isn't necessary since winter is almost over (at least we hope). The cost of these packages added up fast, too. Moving up to the Premium Plus trim over the standard Premium added $3,800. The Technology package was $3,250, the First Edition package was $1,100, and the Sport package tacked on $750. Along with the white paint at $575, our Audi has over $9,000 in options. That brought our tester up to $49,825 from a base MSRP of $40,350. We like everything that's been added. If we were to pick packages we could live without, though, we'd probably pick the Technology and the First Edition packages. As slick as the LCD instrument panel is, there's nothing wrong with physical needles and dials.

Audi SQ7 TDI packs 48V electric compressor, 664 lb-ft

Take a look at the new Audi SQ7 TDI. It's the first time Audi has done an S performance version of its flagship sport-ute, and packs under the hood a 4.0-liter V8 turbo diesel engine mated to an eight-speed automatic and all-wheel drive. It produces a potent 435 horsepower, and an absolutely bonkers 664 pound-feet of torque. The Audi SQ7 TDI produces a massive 664 lb-ft of torque. Impressive as it is, though, that doesn't even tell the full story. That's enough to make us forget it wasn't there in Geneva. It's also more torque than just about anything the Volkswagen Group makes – short of the Bentley Mulsanne Speed and the new Bugatti Chiron. Not even the Lamborghini Aventador SV or Bentley Continental GT Speed can touch that torque figure. Nor can competition like the Porsche Cayenne S Diesel (with its 385 hp and 627 lb-ft) or the BMW X5 M50d (381 hp and 546 lb-ft). It may not surpass the old twelve-cylinder Q7 6.0 TDI (with its 493 hp and 738 lb-ft), but still trounces the VW Touareg V10 TDI (309 hp and 553 lb-ft) – which was strong enough to tow a jet airplane, while the new SQ7 is fast enough to out-drag one (as you can see from the video below). Impressive as it is, though, that headline-grabbing torque figure doesn't tell the full story. To get there, Audi employed two conventional, sequential turbochargers and a third compressor that – in an industry first that's been a long time coming – is powered electrically. The engineers in Ingolstadt installed a beefier 48-volt electric subsystem to power the electric compressor (among other systems) and its latest valvetrain tech for the first time in a diesel. The result, Audi says, is a lack of any perceptible turbo lag – and a 0-62 time quoted at 4.8 seconds, en route to the typical electronically limited top speed of 155 miles per hour. As if that weren't enough, Audi also equipped the SQ7 TDI with an optional suspension package that coordinates the activities of three systems. There's a differential, a four-wheel steering system, and a clever electromechanical roll stabilization system that employs an electric motor (made possible once again by that 48-volt system) and a three-stage planetary gearbox to keep it all level and improve ride quality over rough surfaces. The sum total is an impressive technological tour de force on Audi's part, but one that we may just have to admire from afar.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.
