How Indy 500's JR Hildebrand made an emergency pitstop in Goodland, Kansas

INDIANAPOLIS, In. – Race driver JR Hildebrand is an Indianapolis 500 celebrity, but last week on his way to Indy he was just another repair job at AlexÂ’s Radiator and Auto Repair in Goodland, Kansas. Well, not just any repair job. Hildebrand, a true car guy whoÂ’s just as comfortable driving his bagged 1960 Cadillac Coupe de Ville as he is a 230-mile-per-hour Dallara IndyCar, decided to pull the grand old ride out of storage in Boulder, Colorado, and cruise 1,100 miles to Indianapolis Motor Speedway. At 33, Hildebrand loves the classics, especially cruising in a ride nearly twice his age. It helps him separate from the pull of Twitter, Instagram and text messages before two weeks of foot-to-the-floor stress. Interstate 70 would be his perfect world. Except Â…           View this post on Instagram                       A post shared by JR Hildebrand (@jrhildebrand) “It was highly eventful for the first 300 miles,” said Hildebrand, who is practicing this week for his 11th start in the 500 on May 30.  The Caddy, a 390-powered pink beauty he calls Rosie, “had been sitting for a year, but it fired right up” and cruised just fine early in the trip. But as it approached the Colorado-Kansas state line, the suspension's airbag controller started flickering, the windows were slow to roll up, the gas gauge didnÂ’t work and the engine started to stumble. “IÂ’m thinking maybe IÂ’m only getting seven miles per gallon and IÂ’m out of gas,” Hildebrand said. “So I peeled off, ran a light and got to a gas station. It only took 12 1/2 gallons and was dead. ItÂ’s pretty unlikely that the collector in the fuel tank was leaving six gallons in this thing. I took a jump, and once I got it fired up, I got it back on the road and it ran fine for another 40 or 50 miles, and then the same thing started to happen. I pulled in and got another jump." (His wife Kristin was following behind in their Subaru, along with their dog). He stopped in Goodland and bought a new battery, “figuring the battery was toast at that point, whether that was the problem or not,” he said. “They did their diagnostics thing at the parts store, and it wasnÂ’t totally clear what was wrong.” Assuming the problem was somewhere in the charging system, he headed toward a nearby NAPA only to find it was closed. Along the way, though, he noticed AlexÂ’s Radiator and Auto Repair.

Cadillac CT6 beefs up with 400-hp twin-turbo V6

Cadillac's engine lineup is set to get a makeover led by the potent powerplants under the hood of the CT6. Our man Steven Ewing is onsite at an event in Detroit reporting all the details. Here's what we know so far: The CT6's top engine will be a 3.0-liter twin-turbo V6. It's the first twin-turbo with cylinder deactivation, which essentially makes the V6 able to convert to a V4 unit. Power will be 400 horsepower at 5,500 rpm and 400 pound-feet of torque at just 2,500 rpm. No word on what a potential CT6-V would get. The CT6 will also have a naturally aspirated V6 that Cadillac is claiming to be all-new. It's rated at 335 hp at 6,800 rpm and 284 lb-ft at 5,300 rpm. That's an improvement of 14 hp and nine lb-ft compared with today's 3.6-liter V6, and fuel economy increases nine percent. Cadillac says it's the highest output for a naturally aspirated V6 that's SAE-certified and runs on regular fuel. Both of these V6s will have stop/start technology and will be paired to with eight-speed automatic transmissions. The 3.6-liter V6 will also be used in the 2016 CTS and the 2016 ATS. Meanwhile, Ewing reports that Cadillac says the ATS-V is actually more powerful than initially announced, though there are no numbers to flesh that claim out as yet. The brand also plans to offer four- and six-cylinder diesel engines in various vehicles and new V8 options. The CT6 bows at the New York Auto Show. It will use an aluminum-intensive body that reduces weight by 198 pounds compared with a steel setup and continues Cadillac's creased design language used on the CTS and ATS models. The CT6 goes into production late this year in Detroit.

It leverages the latest technology to balance efficiency, performance and refinement in the upcoming, top-of-the-range CT6 luxury performance sedan. The all-new Cadillac 3.0L Twin Turbo is designed to achieve new thresholds of refinement and specific output for the brand's new prestige luxury sedan, which makes its world premiere March 31, at the New York International Auto Show. Production begins late this year at General Motors' Detroit-Hamtramck Assembly Plant.

Hotter Cadillac CT5-V could use the CTS-V's 6.2-liter V8

Cadillac is in the final stages of testing the high-performance variant of the CT5, prototypes are racking up miles all over the world, and a recent report sheds light on the engine screaming between its punched-out fenders. It's a V8, to no one's surprise, but it's not the twin-turbocharged, 4.2-liter unit many believed the sedan would use. Sources familiar with Cadillac's product plan told Car & Driver the hotter CT5 — whose name hasn't been revealed yet — will receive an updated version of the supercharged 6.2-liter V8 that powered the mighty CTS-V. It developed 640 horsepower in the firm's last German-bashing super-sedan, though where engineers will peg the CT5's output remains to be seen. It will roast the rear tires through a paddle-shifted automatic transmission. The publication explained Cadillac chose the 6.2-liter because it's more compact than the 4.2-liter Blackwing engine it developed for the CT6. The former features a pushrod design, while the latter gets twin overhead cams that make it taller and wider. The CT5 is a new model, but its Alpha platform is older than Cadillac's newest V8. Cadillac hasn't announced what will power the flagship CT5. The model is tentatively due out in showrooms before the end of 2020, so we expect to learn more about it in the coming months. Seeing it in the metal for the first time during the 2020 Detroit Auto Show in June isn't entirely out of the question. What's next? If the report is accurate, the much-hyped Blackwing may end up being an orphan engine. It was developed specifically for the Cadillac brand, and inaugurated by the CT6-V that recently went out of production. The many rumors claiming General Motors will put the engine in other models to recoup its investment are falling like dominoes. It won't fit in the CT5, so there's no reason to believe it will end up in the smaller CT4; its flagship version will likely arrive with a twin-turbocharged, 3.6-liter V6 borrowed from the ATS-V. An earlier report claims the next-generation Escalade won't use the Blackwing, either, because making it fit would cost too much. Looking beyond Cadillac, the only General Motors-owned brand that could use the Blackwing is Chevrolet, since we can't imagine the GMC Yukon will get it if the Escalade doesn't. The Tahoe/Suburban duo is off the table, too.
