2017 Audi S4 First Drive

For all its power and easy performance, the best thing about the last Audi S4 was its uncanny ability to act like a normal (but very high-spec) A4 for most of its life. Then, when you needed or wanted a bit more speed or a bit more grip, you pushed a button or opened the tap and it became something else. It became a thing with more grip, more poise, more focus, and more gristle, but the changeover between the two S4 characters was seamless. That doesn't seem to be the case with the new one. The latest, B9 A4 has been well received and is probably the best mid-sized premium car out there, so that should have left the S4 a simple job to become the best warmed-up premium mid-sizer. It hasn't quite happened like that. The spec sheet suggests the S4 should come out on top in the fight with the BMW 340i and the Mercedes-AMG C43, but the numbers aren't everything. The engine seems impressive on paper; the all-new EA838 3.0-liter turbocharged V6 was jointly developed with Porsche (and it's closely related to Porsche's next V8, with which it will share non-internal bits like the camshaft chain). The 60-degree V6 weighs 31 pounds less than the old S4's supercharged V6, and it's replete with variable valve timing and lift, centrally mounted fuel injectors, and both direct and indirect fuel injection. That gives it 354 horsepower at 5400-6400 rpm (up 6.5 percent) and 369 pound-feet of torque from 1,370 to 4,500 rpm. That gives it a peak 44 lb-ft higher than the old one, spread across a band 600 revs broader. At 2,000 rpm, where drivers live every traffic light, it has another 74 pound-feet. That's enough motivation to move to 62 mph in 4.7 seconds. There's a new all-wheel-drive system that usually shoots 60 percent of the torque to the back but can ramp that up to 85 percent when it needs to, or it can swing it around to fire more than 70 percent to the front axle. The category benchmarks suggest turbocharged 3.0-liter gasoline sixes are the thing to have, with the Mercedes-AMG C43 using one, the 340i BMW having one (though it's straight), and Maserati's Ghibli also using one. The oddball is Jaguar's XE S, which uses a supercharger. You know, like Audi just ditched. The S4 trumps all but the C43 on power (the nine-speed Benz has 362 hp). While it ties the Ghibli for torque, it again trails the Benz (by 15 lb-ft) though its torque peak hits far earlier (the Benz waits until 2,000 rpm).

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.

Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.
