2017 Audi S4 switches to turbo power, loses manual

If you dig the understated look of the 2017 Audi A4 but crave more power, then check out the latest S4. The new sport sedan sticks with a V6 but ditches the supercharger in favor of turbocharging to now produce estimated US figures of 354 horsepower and 369 pound-feet of torque. If there's one downside to the upgrade, it's that Audi only plans to offer the mill with an eight-speed Tiptronic automatic gearbox. The 2017 S4 is now quicker than before. The run to 62 miles per hour takes just 4.7 seconds, versus 4.9 seconds for the current sedan to reach 60 mph. The top speed remains at an electronically limited 155 mph, but fuel economy is claimed to be improved with a rating of 31.8 miles per gallon on the European testing cycle. All S4s come with Audi's venerable Quattro all-wheel drive, and it generally operates with a 40:60 front-rear power split. As conditions change, a maximum of 70 percent of the grunt can go to the front or 85 percent to the rear. Handling is also aided by a tweaked suspension that sits 0.9-inches lower than the A4. Beyond the different badges, the latest S4 doesn't visually advertise its prowess. LED lighting is standard, and quad exhausts rest in a new rear bumper with a subtle diffuser. The side mirror housings also get some aluminum-look trim. The interior layout echoes the A4 but with sport seats and a mix of Nappa leather and Alcantara upholstery. Audi's digital instrument cluster is optional and includes an exclusive sport screen among the three views. The new S4 goes on sale in 2016 as a 2017 model. In addition to the lack of a manual, there's no intention of offering the S4 Avant in the US. Sporty and high-tech: the new Audi S4 and S4 Avant September 15, 2015 | FRANKFURT/INGOLSTADT, Germany Audi launches the new S4 and S4 Avant at the IAA in Frankfurt am Main. The top models from the A4 series are ahead of the competition – with intelligent lightweight design, powerful engines, an extensive package of the latest technologies, and 260 kW (354 hp), 0 to 100 km/h (0 to 62 mph) in 4.7 seconds. (The all-new A4 and S4 are expected to go on sale in the U.S. market in 2016. The Avant is not planned for the U.S. market.) "At Audi, we have more than 20 years of expertise in developing our sporty S models," says Professor Dr. Ulrich Hackenberg, Member of the Audi Board of Management for Technical Development.

2016 Audi R8 looks like a promising second chapter [w/video]

Audi shook up the supercar market when it released the original R8 road car. Now, it's hoping to do the same with the second-generation of the handsome mid-engine star. But where the original R8 was something of an analog supercar, boasting a naturally aspirated V8 and a delightful gated shifter, this new model is something much different. Gone is the popular, high-revving 4.2-liter V8 and the snickety-snack transmission, although the 5.2-liter V10 that joined the original R8 later in its life remains. In base form, it turns out 540 horsepower in the second-gen R8, while the V10 Plus model can be had with an impressive 610 ponies. That's good for a sprint to 60 of just 3.5 seconds and a top speed of 201 miles per hour in the former and 3.2 seconds and 205-mph in the latter. A seven-speed dual-clutch transmission is the sole gearbox, sending power to a revised Quattro all-wheel-drive system that's capable of shunting 100 percent of the engine's torque to the rear axle. Meanwhile, Audi has managed to shave 441 pounds by using a new Audi space frame, with more aluminum and carbon fiber than before. Weighing in at just 3,205 pounds, the R8 is slightly lighter than the new, V8-powered Ferrari 488 GTB, although it's not quite as light as its cousin, the 3,135-lb Lamborghini Huracan. And of course, we can't forget to mention the R8's new look. It's very clearly an evolution of the first-gen's handsome styling. A strong grille and canted headlights, inspired by the TT and the concepts that came before it, highlight the front end, while Audi has opted to bisect the last-gen car's side blades with a body-color section of sheet metal. In back, slim taillights, exhausts that have been integrated into the rear bumper and a central diffuser are the main styling features. Opt for the V10 Plus, and you'll get a sizable rear wing, for added downforce. Take a look at our full gallery of live images from Geneva for a closer look at the new Audi R8.

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.
