Las Vegas Testing Day 2: What can we really learn?

With so many unknowns heading into 2018 and so little information to start guessing what will happen, it’s awfully tempting to jump to conclusions based on little nuggets of data from this week’s Las Vegas test.

For example: William Byron was the fastest in two of the four sessions after never getting in a Cup car before this week. The Chevrolets showed speed with their new Camaro. Kyle Larson had the quickest overall lap time when most teams switched to qualifying trim on the final day.

What’s it all mean? Anything? How much can we really tell from a test?

“You never know who is maybe tuned up trying to raise morale within their own team and who is legit,” Brad Keselowski said. “Usually the bigger teams are fairly legit in these tests. … But you never can really tell for certain.”

For example: Keselowski said Team Penske often does not bring its best cars to the test, and Ty Dillon said some teams might not even bring their best motors.

Learning what the car likes and what adjustments work are more important than chasing lap times, the drivers said. And with so many different agendas, it’s tough to tell how much the lap times matter.

“I don’t think you can really judge it to the fullest,” Dillon said.

Plus, there’s no inspection at the tests — so teams can do whatever they want, in theory (although that would seem like a waste of time considering they came all the way across the country for this).

“You never know who is trying what,” Larson said. “And I honestly don’t even know how far our team has pushed the boundaries for the test.”

Did last year’s preseason test tell us anything? Not really. It was held at Phoenix, and Dale Earnhardt Jr. had the fastest overall lap. He was one of four drivers — Larson, Joey Logano and Kevin Harvick the others — who were in the top five for all four Phoenix sessions.

But that wasn’t a good barometer for the season, since only two of them even made the playoffs and the four drivers combined for just two top-fives in the Phoenix races.

So do we know anything after Las Vegas?

I’m going to say yes. First, we know that when most teams actively tried to post a fast lap at the end of the test, it was Larson who had the advantage.

“When we switched to qualifying trim, we were faster than everybody here,” Larson said. “I don’t know how that would be if it were a full field, but I felt happy overall.”

Also, there was a frequent pattern for most of the two days: Larson, Ryan Newman (second-fastest overall) and William Byron were consistently near the top of the charts.

All of those drivers race for Chevy teams, who have a new nose this year.

“I think you can get some sort of an idea (of who is fast),” Larson said. “The Penske group, whenever I’ve done tests with them, they’re not as competitive at the test and then they come back at the race and they’re really fast.

“But overall, our balance felt really good. So you can take that at least and know you’re going to come back to the majority of the mile-and-a-halfs and be competitive.”

Las Vegas Testing Day 1: William Byron shows speed

Prior to getting on track Wednesday at Las Vegas Motor Speedway, William Byron had never been up to speed in a Cup Series car.

Considering he’s getting ready to drive Hendrick Motorsports’ famed No. 24 car this season, there’s a lot for Byron to learn in a very short amount of time.

But on his first day as a Cup driver, the 20-year-old showed promise almost immediately — and left him hardly able to stop smiling after seven hours of testing.

“Just a lot of nerves showing up at the racetrack today and seeing all the cars and the guys you’re used to watching on TV,” he said. “It’s kind of weird being at a test with them or being on the track with them. But once I got in the car, I just kind of trusted what has gotten me here and what I’ve done to this point.”

Those instincts paid off. Byron was initially about a half-second behind the leaders following his first run, but was the fastest driver in the morning session by the time lunch rolled around. His speed was the second-fastest of the day, with Kyle Larson edging him by .012 second.

“Everyone was telling me not to look at the lap times, because they don’t want me to bust my tail or something,” he said with a chuckle. “But the biggest thing for me was once I knew what my comfort level was, I could push the car more and see the lap time kind of result in that.

“Obviously, it’s just a test. You’re not racing guys. I’m sure I’ve got a ton to learn, especially racing around guys. So I’m sure it’s going to be a difficult task to get used to that, but at least we have the speed.”

Until Wednesday, the only seat time Byron had was to practice with the gears (and in the simulator, of course). But he’d never actually made a lap.

He described the experience as like driving a rocket ship.

“The first time, I was just trying to hold on,” he said. “I think each run, I started to get more and more comfortable. But you still never really get comfortable with the speed of it — it’s tremendous, especially in the mid-corners.”

With Day 1 behind him, Byron knows he can at least get up to speed in a Cup car — and that he’ll likely have fast cars to drive this season.

“The new Camaro is good so far, and I think if we can keep building on that on (Thursday) — not crash it or anything — we can get out of here with some good information,” he said. “It’s been a lot of fun.”

Day 1 combined top single-lap speeds (I took the driver’s top speed from the morning and afternoon sessions):

Phoenix Raceway organizational test session times

Disclaimer: These came in raw data, so I had to pull them from a spreadsheet and it’s possible I screwed up.

I put these in order of best lap times, not mph, because the data is more detailed in seconds than speed. Also, these are the top time from each individual driver, not overall (Joey Logano had 19 of the 24 fastest laps in the Tuesday morning session; Dale Earnhardt Jr. had 13 of the fastest 15 laps in the Wednesday morning session).

Here are the single best lap times from the Tuesday morning test session:

  1. Kyle Larson (Ganassi) — 26.586 seconds
