Indy 500 young guns Sage Karam, Conor Daly ousted early

First-lap incident, mechanical issues take out two American racers

The Indy 500 brought nothing but heartbreak for a pair of young American drivers. Conor Daly and Sage Karam, ages 23 and 20 respectively, saw their Indianapolis dreams go up in smoke before the first lap ended.

Daly, an Indianapolis native, didn't even make it through the parade laps as mechanical failure claimed his car. On the second parade lap, the Schmidt Peterson Motorsports driver was forced to pull off the course as smoke and flames were trailing from the rear of his No. 43 Honda.

An overheated exaust system was the culprit that ended Daly's day.

"I don't really know what happened," Daly said. "We just started seeing smoke. Nothing felt bad and then it just shut off. This is my only opportunity all year, so to not be able to start is devastating."

Karam's exit from the race might have been even more frustrating.

Approching the second turn of the first lap, Karam was racing side by side with Ryan Hunter-Reay. As they went into the turn, Takuma Sato attempted to pass Karam on the right, going three wide into the corner.

Sato didn't have room and Karam crashed right underneath the Foyt Racing Honda. Karam made no effort to mask his displeasure with his fellow driver.

"I don't know what Sato's doing,"  Karam said. "Kind of a bonehead move. He sees me and (Ryan) Hunter-Reay side by side, and the first lap he's trying to make it three wide. I just don't get it. The track's clean right now, it's swept so there's no marbles up there and you can run high, but no reason to push a three-wide issue.

"I mean, just a very stupid move on his part. We had a good start, going through turn one picked up about two spots already, was running side by side with Hunter-Reay, everything was cool. And with Sato, he had a big run, yeah, but he doesn't need to go popping outside on lap one, turn one. It just doesn't make sense. It ruins a lot of people's races, you know."

After a month of preparation, it's no doubt frustrating to be ousted from one of the biggest races in the world, but for Daly and Karam, there is even more at stake.

Neither driver has a full-time ride in the IndyCar series, and both were hoping to turn in a successful run at IMS in order to bolster their stock with team owners.

"Everyone only looks at results, so I don't know what's going to happen now," Daly said. "It certainly would have helped more than hurt. I don't know where we go from here. We'll just have to see what happens."

2016 Chevrolet Camaro Prototype Drive: Early Indications Are, Um, Positive

When the current, fifth-generation Chevrolet Camaro arrived as a 2010 model, it ended the nameplate’s seven-year absence from the market and finally banished the Camaro’s image as a crude muscle car. With its independent rear suspension, solid structure, and strong powertrains, the fifth-generation Camaro was thoroughly modern.

Yes, it was still large and heavy, and its high beltline combined with its chopped roof gave it somewhat of a cartoonish image and compromised visibility. But it successfully incorporated cues from the original, 1960s Camaro and was instantly recognizable, and appreciated, by Chevy enthusiasts. Not only did the fifth-gen model sell well over half a million copies during its six-year production run, but it also outsold its crosstown rival, the Ford Mustang, for the first time in memory.

Unmistakably a Camaro

As a result, Chevrolet has concluded that Camaro buyers aren’t looking for styling innovation. “From every angle, you’ll never mistake this for anything but a Camaro,” says Tom Peters, Camaro design director. That’s for sure, but the new model also looks both more muscular than before and a bit cleaner. For example, the pseudo vents punched into the sheetmetal forward of the rear wheels are gone, but the dip in the middle of the roof is more pronounced. This seems opposite to the direction that Ford has taken with its new Mustang, which is decidedly busier looking than its predecessor.

The close aesthetic resemblance between the gen-five and gen-six Camaros might suggest that the new car is simply an upgraded version of its predecessor, but nothing could be further from the truth. While the old model was built on GM’s Zeta platform, which originated in Australia and also underpinned the late Pontiac G8—and the current Chevrolet SS—the new Camaro is built on GM’s Alpha platform, which debuted on the Cadillac ATS three years ago.

The Alpha platform is both stiff and light. As a result, the new Camaro’s body-in-white—basically the bare body shell before any suspension, interior, or exterior panels are attached—weighs 133 pounds less than the previous-gen equivalent.

An aluminum dashboard crossbar saves a further nine pounds, and the suspension is 26 pounds lighter thanks to extensive use of aluminum and carefully optimized steel components. Overall, the Camaro SS is said to shed about 200 pounds despite a slightly heavier upgraded V-8 engine, while the Camaro LT is more than 300 pounds lighter, according to Chevy, thanks to the new standard four-cylinder engine. We’re looking forward to quantifying the weight savings on our own scales soon.

New Base Four

Lest you be alarmed that this portends a return to the gutless, “Iron Duke”–powered Camaros of yesteryear, the new base engine is the 2.0-liter turbocharged four used in the ATS, developing 275 horsepower and 295 lb-ft of torque. It will be available with either a Tremec TR3160 six-speed manual or GM’s new 8L45 eight-speed automatic—a smaller version of the 8L90 that debuted in the Corvette. It weighs 33 pounds less than its beefier big brother. Chevy promises that zero-to-60 times for the four-cylinder Camaro will be in the five-second range, with EPA highway fuel economy said to land in the 30s.

The middle engine option will be the company’s new 3.6-liter V-6. This engine is a thorough redo of the existing V-6 with its cylinders spread farther apart, a slightly larger bore, a quieter cam-drive system, and variable displacement. It’s lighter than the previous V-6 and will develop 335 horsepower and 284 lb-ft; it also will be available with both transmissions.

The SS model will come with the LT1 V-8, the latest iteration of the small-block V-8 that was introduced in the C7 Corvette Stingray. With direct fuel injection and variable cam timing, it provides an excellent combination of power and efficiency. It will also come with manual and automatic transmissions, the Tremec TR6060 and the GM 8L90. You’ll note that those are beefier versions of both transmissions to match the V-8's output of 455 horsepower and 455 lb-ft, increases of 29 hp/35 lb-ft over today’s LS3 V-8 and 55 hp/45 lb-ft versus the current L99 engine.

Preview Drive

We had no opportunity to drive the SS V-8, but we did get a few minutes behind the wheel of both manual and automatic LT V-6 models on the ride-and-handling loop at GM’s Milford Proving Ground.

Unfortunately, the development cars had so many squeaks and rattles that it was impossible to determine if they were any more refined than the perfectly-screwed-together fifth-gen cars on hand for comparison. In fact, these examples, at the end of their production cycle, were as smooth and quiet as any Camaros we’d ever driven.

However, we did determine that the TR3160 manual transmission is a smooth and satisfying gearbox, and we were particularly impressed by the new 8L45 automatic, which shifted smoothly and decisively, whether driven gently or aggressively. The eight-speed executes quick and slick full-throttle kickdowns, even when dropping four or more gears at a time.

During this full-throttle work, the optional dual-mode exhaust leaves no doubt that the Camaro philosophy was first dictated in the muscle-car era of the 1960s. In fact, between the loud exhaust, the “sound enhancers”—essentially calibrated firewall noise leaks—and the bucket-of-bolts feeling of these prototypes, it was impossible to determine whether the new V-6 was any smoother at high revs than its thrashy predecessor.

There was no opportunity to explore handling, but we did get a sense that the new electric power steering is a decent example of the breed, delivering close to the steering feel of the hydraulic power steering in the current V-6 versions. And we picked up some hints of improved agility, thanks to the lighter weight and the upgraded suspension.

The driving position is much as it was before, with a high beltline and a narrow view out, although the cowl is about an inch and a half lower. This feeling of being buried in the cockpit is particularly strong if you lower the seat all the way, as it goes down farther than it did before. Taller drivers will appreciate this change. For the rest of us, it will pay to raise the seat roughly halfway. Also appreciated are the thinner A-pillars—they’re about an inch less thick front to rear and half an inch leaner from the side. Both changes provide a welcome improvement in visibility. For those who care, rear head- and legroom are slightly reduced thanks to the car's slightly smaller overall dimensions.

The traditional instrument cluster in a hooded binnacle is retained with the new Camaro, but the four minor dials in squarish housings just forward of the shifter are gone, replaced by a configurable LCD display between the speedo and tach. A second LCD display—an 8.0 incher—sits in the center of the dash when you order the navigation system.

Coupled with the strip of subtle heating and A/C controls, which include temperature-setting dials nicely integrated into the two low-mounted center vent registers, the overall interior ambiance strikes us as clean, uncluttered, and user-friendly.

We look forward to driving the fully developed versions of these cars, but for now, it’s clear that with this new Camaro, Chevrolet has stayed true to a successful formula while improving the car on many fronts. Camaro fans will be delighted.
