Team Penske-Chevrolet's Josef Newgarden earned his second IndyCar title in three years, but as well as the usual suspects – including Indy 500-winning teammate Simon Pagenaud – Newgarden faced strong opposition from a couple of brilliant rookies. Meanwhile, nine wins from Penske wasn't enough to stop Honda beating Chevrolet to the manufacturers' crown for the second straight year. David Malsher reflects on another entertaining season.

One of the newest team owners in the NTT IndyCar Series, Trevor Carlin, says that allowing the bigger teams to grow unchecked will drive the smaller teams away as they struggle to achieve the kind of results that attract sponsors.

Plenty of hope and promise, not enough points and too many drivers – Carlin’s sophomore season in the NTT IndyCar Series was bewildering. The one constant was its team principal’s determination and his employees’ hunger for success. Trevor Carlin tells David Malsher how the team got through it and how the work ethic hasn’t changed for 2020.

The Arrow McLaren SP team – formerly Arrow Schmidt Peterson Motorsports – is sending personnel to the Mexican and US Grands Prix as guests of the McLaren Formula 1 team, but the team denies that this suggests an imminent announcement regarding Patricio O’Ward.

IndyCar’s new-for-2020 aeroscreen is a welcome step forward in terms of cockpit protection – but it brings with it some technical challenges, as James Hinchcliffe’s race engineer at Arrow McLaren SP, Will Anderson, explains to David Malsher.

Josef Newgarden says he grew accustomed to IndyCar’s aeroscreen after just 30-40 laps of Richmond Raceway, as he and Scott Dixon began testing at the 0.75-mile oval which returns to the NTT IndyCar Series in 2020.

Roger Penske has invited Supercars team boss Roland Dane to run an Indy 500 wildcard entry – but with some cheeky conditions.

Rinus VeeKay, 2019 Indy Lights runner-up, will get a second test with Ed Carpenter Racing next Tuesday at Mid-Ohio SportsCar course.

IndyCar’s Red Bull Advanced Technologies aeroscreen looks odd from the head-on angle, sexy from the side – but if it protects the drivers and they approve of its application, aesthetic appeal ceases to be a priority, writes David Malsher.

Chip Ganassi Racing will enter a third IndyCar next season as Marcus Ericsson joins fellow Swedish series sophomore Felix Rosenqvist and five-time champion Scott Dixon.
