Five cylinders, no waiting | 2018 Audi TT RS First Drive

A five-cylinder engine is an odd duck in the modern automotive world, so why put it under the hood of a sophisticated sports car like the 2018 Audi TT RS? We're posing this question to an engineer when a loud, guttural sound interrupts the conversation. A TT RS blasts by, growling and percolating as it shoots down the front straight of the historic Circuito del Jarama in Spain. Oh, that's why. The RS treatment brings the sound and the fury to the TT, transforming a cute, sporty little car into a sports car with mettle. With 400 horsepower channeled to all four wheels, a stiffer suspension, and styling flourishes like organic LED taillights, the RS makes for a big-time upgrade over the 292-hp TT S and the mild-mannered 220-hp TT. Who wants a four-cylinder, anyway? We're considering the five-pot's potential as we mash the throttle and explode onto Jarama, an old Formula 1 course that still looks ready to host top-level racing. There's a couple of long straights and lots of curves and elevation changes. Sure, it's a bit trite to praise a sports car after a few laps in a controlled setting, but the TT RS has legit performance chops. The engine sounds just as good inside the car as it does to spectators, and it's more satisfying since we're the ones provoking the five cylinders to anger as we approach triple-digit speed. It's all real, too. There's no pumped-in sound or fake flatulent exhaust. "It's the unadulterated sound of the engine – we didn't change it," says Philipp Ade, Audi technical project manager for powertrain. Speaking trackside through an interpreter, he admits the exhaust system adds resonance but also filters out other noises to produce a clean engine note. Trust us, you'll want to tune in. The five-cylinder is not a glorified sound check. It's a new engine developed for Audi's smaller performance cars, though the TT RS is the only one confirmed for the United States. The 2.5-liter mill uses aluminum for its block and crankcase and magnesium for the oil sump. This all results in a 57-pound weight loss compared with the old five-cylinder, which was last sold in the US market in the previous-generation TT RS for the 2012-13 model years. That car was brought to the states after a Facebook campaign. This time there was no doubt Americans have an appetite for the hottest TT. A non-enthusiast will wonder: why the fuss over a five-cylinder engine? To Audi and its band of loyal followers, it's a defining element of performance.

Audi first to bring LTE to the car later this year

It appears Audi will be the first to market with in-car LTE service later this year. We knew that BMW was working on LTE integration last year with its ConnectedDrive, and we've been told that, by the end of 2015, most General Motors products will have it, but LTE can be ordered on the S3 Sportback (pictured) as soon as July. Other models in the A3 line-up will add the option in November.
Inserting an LTE-enabled SIM card into the Audi's MMI navigation will make the S3 a WLAN hotspot that can quickly shuffle high-definition content from the cloud to the cockpit. It will also bolster Audi Connect services like Google Earth, Facebook and Twitter, e-mail, and streaming internet radio.
We've been told that we'll be offered the LTE option when the 2015 A3 sedan gets here in the spring of 2014. Since the service requires you to provide a SIM card, we expect that costs and data caps will be a matter between you and the service provider; speaking of which, Audi hasn't announced yet who that provider will be on this side of the Atlantic. The press release below has more details.

Startup will make your Audi A4 self-driving for $10k [w/video]

We are on the cusp of the next generation of semi-autonomous driving technology becoming affordable. Adaptive cruise control is already trickling down to the mass market, and the more sophisticated systems found on vehicles like the Mercedes-Benz S-Class are clearly coming, as well. If you're a little adventurous, live in California and drive an Audi, you might be able to upgrade to the next stage of driverless tech even sooner. A San Francisco start-up called Cruise Automation is launching an aftermarket autopilot system called the RP1 for $10,000, with deliveries starting in 2015.
The RP1 is designed for 2012 and newer Audi A4 and S4 models. Although, Cruise CEO Kyle Vogt told Autoblog in an email: "There's no reason we can't expand to other cars, and we will." The system includes a sensor pod on the roof containing cameras, radar and other sensors to scan the road ahead. It then sends data to a small computer mounted on the side of the trunk. The desired inputs are then made by actuators for the steering, brakes and throttle to control the car. A button in the cabin activates the autopilot and controls the desired speed. Not completely unlike Audi's own, developmental, semiautonomous system.
At this point, the RP1 is somewhere between an adaptive cruise control system and an autonomous vehicle. It can control all of the cars inputs and even bring it down to a complete stop and then accelerate again. However, it only works on select highways in California. "We use geofencing to limit the areas of operation to segments of highway in which we've collected enough data to ensure our customers' safety," said Vogt to Autoblog.
