3GT Racing has signed drivers Jack Hawksworth and Robert Alon to pilot the No. 15 Lexus RC F GT3 in the IMSA WeatherTech SportsCar Championship next year.

The signing of Hawksworth and Alon completes 3GT Racing’s 2017 full-time driver lineup. The duo joins Sage Karam and Scott Pruett, who will pilot the No. 14 Lexus entry.

“I’m really looking forward to racing a Lexus for 3GT Racing,” said Hawksworth. “Paul [Gentilozzi] has shown a lot of faith and belief in me since our first race together in 2014. This is a fantastic opportunity and I know we are destined to do great things together.”

Hawksworth has a previous WeatherTech Championship victory in the PC class with RSR Racing at Indianapolis Motor Speedway in 2014.

Team principal Paul Gentilozzi said the two drivers were selected after extensive testing of ten drivers in Michigan in September.

“I’m honored to be a part of such a great partnership between 3GT Racing and Lexus,” said Alon.

“I’m also very excited to be teammates with some of the best in the business and can’t wait to get behind the wheel of the Lexus RC F GT3 later this month in Daytona.”

The 25-year-old Hawksworth moved from England to the U.S. in 2011 and began competing in the Star Mazda Series the next year. He claimed the series championship in 2012 by breaking the Star Mazda record for most wins and poles.

Hawksworth went on to compete in the Verizon IndyCar series from 2014 through 2016 where he won the Tony Renna Rising Star Award in his rookie season. He also won in the Indy Lights Series in 2013.

Alon, who just began racing in 2014, captured three PC class wins and four poles in the WeatherTech Championship this year, and he has also previously competed in the Cooper Tire Prototype Lites Series and the LAKC Series.

“We have been very fortunate to have the patience and opportunity to test many prospective drivers for our program,” said Gentilozzi.

“Choosing Robert and Jack was the result of our team’s analysis of both their on-track driving, social skills, fit in our structure and competitive maturity.

“That maturity does not always mean just the number of years they have raced, it reflects on their ability to bring our Lexus to the finish every race.”
