Numerous issues have modified in Audi’s inline five-cylinder motor since its introduction: horsepower, torque, displacement, supplies, however one factor stays the identical: its firing order. Audi’s beefed-up, sometimes-street-sometimes-race engine went from 350 hp within the Quattro A1 rally automotive, to 600 hp within the Sport Quattro S1, to 720(!) hp within the insane-looking Audi 90 Quattro IMSA GTO.
It’s been a protracted highway to the 2018 TT RS and RS3 road vehicles. Audi’s new aluminum-block, hollow-crank 2.5-liter turbocharged 5 is 57 kilos lighter than its road-going predecessor and now makes 400 hp and 354 lb-ft of torque, which maxes out between 1,700 and 5,850 rpm. However the order, 1,2,four,5,three, is similar as 37 years in the past.
The TT RS and RS3, each on sale now, are constructed on the identical MQB platform, have the identical I5 and seven-speed S-tronic dual-clutch transmission and have almost the identical inside. However they’re two very totally different vehicles. OK, not that totally different, however between the 2, they’ve many of the fanatic market lined, together with the “younger prosperous household” demo, who would possibly want greater than the laughable rear seat within the TT RS, even when it does cut up and fold.
Each fashions are differentiated from their lesser siblings with RS Singleframe grilles, matte aluminum trim (besides when it’s black), the RS script, clearly, and the oval tailpipes. The A3 has two spherical suggestions, the S3 has quad suggestions; solely the RS fashions get the ovals. And solely these two get the mixed-up, growling sound of a real inline 5.

In the event you’ve by no means heard an inline 5 pushed in anger, nicely, first take a second and watch this — we’ll wait. Within the TT RS and RS3, it appears like a whooshy, raspy, offended swarm of hornets, but in addition a little bit bit like a tweaked-up 4 with a plastic cold-air consumption. Each get launch management, good for Zero-60 occasions of three.6 and three.9 seconds for the TT RS and RS3, respectively. High pace is 174 mph for each, so long as you specify the Dynamic plus package deal ($6,000-TT RS, $four,800-RS3), which comes with entrance ceramic brakes, OLED taillights on the TT RS, carbon-fiber engine cowl and a hard and fast sports activities suspension as an alternative of the magnetic adjustable setup.
The cockpits are comparable, however not similar. The TT RS has Audi’s Digital Cockpit, which places all of the infotainment within the gauge cluster; the RS3 has a pop-out central display screen. They each get a leather-based and alcantara steering wheel, MMI contact to regulate the infotainment, computerized local weather management, aluminum or carbon inlays and semi-out-of-place-looking seats with contrasting diamond stitching. An alcantara-covered, racquetball-size shift knob pokes out from between the manually adjustable seats within the RS3 and power-adjustable seats within the TT RS.
Each vehicles are supposed to evoke the Quattro race vehicles of yore, and so they each succeed.

Pulling the RS3 out of the pits at Lime Rock heading on to Sam Posey Straight, it’s the sound that’ll catch your consideration first. A second later, it’s the pull of energy from all 4 wheels. Turns one and two meld into one super-late-apex sweeper, and placing the ability down on exit is simple with the quattro system deciding the place to ship torque. It will probably go anyplace at any time, says Audi, together with 100 p.c rearward with launch management. However we’ll get again to that in a minute.
Flip three, The Left Hander, is one other late apex, and that is the place RS3 confirmed some understeer. It was the identical within the TT RS, although when Le Mans-winning scorching shoe Hans-Joachim Caught took the wheel there have been equal quantities of below and oversteer because the Haldex setup found out how you can cope. For the extra earthly drivers, letting the throttle breathe for a second brings the entrance finish again to the racing line, after which it’s again to full energy, as quickly as attainable. Audi makes a speciality of easy-to-drive-fast vehicles (the R8 is considered one of them), and the TT RS and RS3 are as forgiving as any. In reality, Stephan Reil, head of Audi Sport product improvement, stated that an ace driver can lap the Nurburgring 15 seconds sooner within the R8 than within the TT RS; an important driver is just 5 seconds sooner and a superb driver will really get a greater time within the child coupe.
After The Proper Hander, The No Title Straight is the place the pace actually picks up. The previous nook permits a 40-50 mph exit, and by the following flip, the TT RS hit 90 whereas the RS3 was nearer to 85 mph. That is the toughest braking spot on the course — we took the chicane route versus the straight uphill part — and each vehicles have the identical, soft-but-sensitive pedal really feel. There’s a tad extra journey than you would possibly like, however the entrance ceramics had been fade-free. A observe on that: Contemplating that entrance brakes take the lion’s share of the work, often greater than 60 p.c, placing ceramic discs solely on the entrance wheels is likely to be a cheerful medium, particularly on the subject of shopping for replacements.
After that, it’s a four-story drop earlier than a tough, blind braking zone after which again to the entrance straight. Audi despatched us by way of the pits on every lap. Each the TT RS and RS3 may hit nicely over 120 mph given the total observe — somebody really noticed 130 mph with Caught behind the wheel.
General, the TT RS feels a half-step sooner in each facet. It’s barely faster to show in, barely faster to energy out and barely faster to drop pace. The seating place is about the identical, however because the TT RS is decrease normally, it felt extra hunkered down at pace. Sightlines are about the identical too. Each pillars are form of angled towards the motive force; you’ll hardly ever want to maneuver your head to see round a nook.
The seven-speed dual-clutch transmission is tremendous fast, and it is almost instantaneous on upshifts. Downshifts take a microsecond or so. In dynamic mode, which adjusts the steering, suspension (with the magnetic journey), exhaust sound — only a valve, no fakies — torque cut up and the engine/transmission mapping, each the RS3 and TT RS rev increased and shift later, however on the observe, you’ll nonetheless want the paddle shifters for completely timed modifications. And when the thrust actually hits at three,200 rpm or so, you’ll wish to be prepared.
On the sleek, curvy again roads close to Lime Rock Park, the TT RS, with the upgraded, nonadjustable suspension, was proper on the border of too stiff. When the pavement will get wavy in concord, the seatbelt must maintain you in place. The RS3 has a number of further kilos — three,593 kilos to three,306 kilos — which makes it way more agreeable over the tough stuff. In reality, the rear seats within the RS3 make it way more agreeable normally. With a 5-foot, 10-inch grownup in entrance, there’s a superb 6 inches of legroom within the rear. It’s nonetheless not beneficial for four-person, 40-hour highway journey, although. These seats are a little bit vast for a slim body, however for a barely wider driver, they’d be good.
The steering is variable ratio and progressive, so it will get tighter as you wind it up. It makes these choices based mostly on wheel pace, steering angle and different elements. It’s each mild and fast, much like the R8. So far as “highway really feel” goes, it’s electrically boosted so it’s not nice, however once more, professional drivers like Caught, and good newbie drivers, use their guts and butt (the poupa!) to really feel the place the restrict is.
The enter you do get is from 235/35 R19s on the RS3, including the Dynamic pack modifications them to 255/30 R19 fronts and 235/35 R19s rear. The TT RS comes inventory with 235/35 R19s, upgradable to 255/30 R20s. There have been Pirellis on our check automotive, however Audi says like most producers, it has two tiremaker choices.

The 2018 TT RS stickers for $65,875, together with a $975 vacation spot charge. The RS3 is a little bit cheaper at $55,875. That places them nicely above extra pedestrian scorching all-wheel-drive rivals just like the Subaru WRX STI ($36,955) and Ford Focus RS ($36,995), each of which have much less energy, and only a contact increased than the Mercedes-AMG CLA 45 ($51,395). The BMW M2 ($52,500), which is likely to be the rear-wheel-drive fanatic’s selection, is correct in the identical wheelhouse.
There’s one thing about driving a five-cylinder. It’s the sound, each on startup and at pace, the thrust, and the truth that someway engineers are in a position to steadiness it, as loopy because it appears. To not point out the 37 years of historical past. However is that sufficient to return to the dealership with these further ducats? Audi offered about 2,700 TTs final 12 months, down from about three,000 the 12 months earlier than. The RS3 is new to the U.S., so we don’t have earlier numbers, however with its mixture of sportiness and four-door comfort, will probably be the larger vendor. And for a newly minted household man, in search of an entry-level sporty luxurious compact, it’s most likely the one to purchase.
