Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

2017 Audi A4 pricing drops before Detroit debut

With its spring 2016 on-sale date rapidly approaching, Audi confirms the official pricing structure for the new A4 sedan. The four-cylinder-only A4 line starts at $38,250 – a $1,400 increase over last year's model – but like the similarly priced BMW 328i and Mercedes-Benz C300, that figure climbs quickly. For one, unless you're planning on living with a front-wheel-drive Audi, you'll need to add on $2,100 for the automaker's torque-vectoring Quattro all-wheel-drive system. And unless you want the basic Premium trim, plan on tacking on $3,800 for the Premium Plus trim or $8,600 for the range-topping Prestige. What's all this mean? For that, we'll turn to the newly switched-on online configurator. The standard A4 doesn't sound like a terrible deal, offering standard bi-xenon headlights, LED taillights, three-zone climate control, leather seats, a sunroof, and a seven-inch MMI system. Moving up to the Premium Plus switches up to full LED headlights, heated front seats, a 19-speaker Bang and Olufsen 3D stereo, push-button start, and an S-line exterior treatment. Finally, the top-line Prestige's notable standard items include an 8.3-inch, nav-equipped MMI system, Audi's excellent virtual cockpit (an Autoblog Tech of the Year finalist), and a head-up display. If you're balking at the trim packs, rest easy knowing Audi has spread the options around liberally. You can get navigation and heated seats on a base model – they're $2,400 and $900, respectively – and Virtual Cockpit can be added to the mid-grade model. The base can be had with standard 18-inch wheels, while the Premium Plus allows drivers to ditch the 18s and move up to 19s. Even the top-of-the-line Prestige has a few options, including an $1,800 Driver Assistance pack (adaptive cruise, auto high beams, and lane keeping assist ) and a $1,450 Warm Weather Pack (vented front sport seats). While you can get an A4 for $38,250, you can also build one up to $55,375. Look for the 2017 Audi A4 in dealerships this spring. And head over to the online configurator to build your ideal Audi sedan now.

2017 Audi S5 First Drive

Let's start with the obvious elephant in the room: The new 2017 Audi S5 looks mostly like the model it replaces. Is that a bad thing? We headed to Portugal to test out the S5 on that country's serpentine back roads, and to see if there's something more substantive behind its evolved exterior. Only compared to the decidedly more evocative Mercedes-AMG C43 Coupe does the svelte S5 come across as a little frumpy. It takes parking the new S5 next to the old one to spot the details. A tweaked profile. A more pronounced belt line. A power-dome hood. Narrower A-pillars. The new S5 is different, but the same, in that grand Audi tradition. Underhood, the differences are again evolutionary. The original S5 featured a 4.2-liter, naturally aspirated V8. A few years back, that was replaced by a supercharged 3.0-liter V6, which in turn has been supplanted in the 2017 S5 by a turbocharged 3.0-liter V6. The turbo, a twin-scroll unit nestled between the cylinder banks, helps the direct-injection engine make a healthy 354 horsepower and 369 pound-feet of torque. That power, 21 hp and 44 lb-ft more than its predecessor, is channelled through Quattro all-wheel drive. The newly developed V6 mates exclusively to a conventional eight-speed automatic, which seems like a step backward. Last year's S5 offered either a six-speed manual or a seven-speed dual-clutch gearbox. We pressed Audi and got the answer we expected: Demand for the stick was nonexistent outside the United States (go America!) and the dual-clutch couldn't handle the 44 pound-foot increase in torque. Curiously, the A5 on which the S5 is based trades last year's eight-speed autobox for a seven-speed dual-clutch. It sounds like someone at Audi put the wrong transmission in each car, but in reality the S5's torquey engine is well-suited to the refined eight-speed. Kick the throttle, get into boost, and all four drive wheels scrabble for traction, especially on the wet pavement we encountered outside of Porto, Portugal. Punch the S5 to pass on a tight two-lane road and the sport exhaust roars with the kind of guttural growl we want to hear in a sporty coupe. It positively scoots. Though its Volkswagen MLB 2 platform is new, the S5 rides and handles like a more refined version of its predecessor. Considerably less road rumble penetrates the cabin, and the S5 strikes a pleasant balance between grand-touring plush and sports-car firm.
