IT'S A SCIENTIFIC FACT: Low weight plus high horsepower equal exhilarating performance. That combination has defined the Corvette for six decades, as increasing power output matches the use of advanced materials to minimize curb weight, reports Chevrolet, which was founded in 1911 in Detroit.
The 2013 Corvette Z06 exemplifies that philosophy. With a curb weight of only 1,451 kg and 505-horsepower, it is not only one of the lightest sports cars available in America, it has one of the best power-to-weight ratios of 6.33:1, which is better than key competitors.
"Horsepower isn't the only measure of performance," said Harlan Charles, Corvette's marketing manager. "Balance and low weight are just as important and that's where the Corvette excels. It has a heritage of employing cutting-edge technologies and materials to help optimize performance."
Corvette's use of advance materials began in 1953, when the first Corvettes were produced with all-fiberglass bodies. Every Corvette since has featured a composite-material body.
Fiberglass, the lightweight, rustproof composite material, was first considered for use on a GM vehicle by legendary designer Harley Earl. Besides being an exotic choice for the early Fifties and having an undeniable weight advantage, fiberglass offered an economical way to create the low-volume Corvette without the expense of large sheet metal stamping dies.
Starting with the third generation in 1968, the body parts were manufactured with a press mold process, whereby the fiberglass material and resin were shaped in a die-like tool that produced smoother parts more quickly. It was a significant advancement in forming technology and laid the groundwork for a change in the body panels' material in 1973. That year, the composition changed from conventional fiberglass to sheet-molded composite, or SMC, which was composed of fiberglass, resin and a catalyst formed under high heat and pressure.
All Corvettes since 1973 have used SMC body panels, but the material composition has changed dramatically, featuring less traditional fiberglass and more lightweight plastic.
Chevrolet is now one of the world's largest car brands, doing business in more than 140 countries and selling more than 4 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design and high quality.

Second doctor in Matthew Perry overdose case sentenced to home confinement
- Dr. Mark Chavez, 55, a onetime San Diego-based physician, pleaded guilty in federal court in October
- Judge Sherilyn Peace Garnett also sentenced Chavez to 300 hours of community service
LOS ANGELES: A second California doctor was sentenced on Tuesday to eight months of home confinement for illegally supplying “Friends” star Matthew Perry with ketamine, the powerful sedative that caused the actor’s fatal drug overdose in a hot tub in 2023.
Dr. Mark Chavez, 55, a onetime San Diego-based physician, pleaded guilty in federal court in October to a single felony count of conspiracy to distribute the prescription anesthetic and surrendered his medical license in November.
Judge Sherilyn Peace Garnett also sentenced Chavez to 300 hours of community service. As part of his plea agreement, Chavez admitted to selling ketamine to another physician Dr. Salvador Plasencia, 44, who in turn supplied the drug to Perry, though not the dose that ultimately killed the performer. Plasencia, who pleaded guilty to four counts of unlawful drug distribution, was sentenced earlier this month to 2 1/2 years behind bars.
He and Chavez were the first two of five people convicted in connection with Perry’s ketamine-induced death to be sent off to prison.
The three others scheduled to be sentenced in the coming weeks — Jasveen Sangha, 42, a drug dealer known as the “Ketamine Queen;” a go-between dealer Erik Fleming, 56; and Perry’s former personal assistant, Iwamasa, 60.
Sangha admitted to supplying the ketamine dose that killed Perry, and Iwamasa acknowledged injecting Perry with it. It was Iwamasa who later found Perry, aged 54, face down and lifeless, in the jacuzzi of his Los Angeles home on October 28, 2023.
An autopsy report concluded the actor died from the acute effects of ketamine,” which combined with other factors in causing him to lose consciousness and drown.
Perry had publicly acknowledged decades of substance abuse, including the years he starred as Chandler Bing on the hit 1990s NBC television series “Friends.”
According to federal law enforcement officials, Perry had been receiving ketamine infusions for treatment of depression and anxiety at a clinic where he became addicted to the drug.
When doctors there refused to increase his dosage, he turned to unscrupulous providers elsewhere willing to exploit Perry’s drug dependency as a way to make quick money, authorities said. Ketamine is a short-acting anesthetic with hallucinogenic properties that is sometimes prescribed to treat depression and other psychiatric disorders. It also has seen widespread abuse as an illicit party drug.
