Aside from Scott Dixon, which drivers can offer a genuine title threat to the Penske trio?
David Malsher: If Andretti Autosport is back on form then I have no doubts that Ryan Hunter-Reay and Alexander Rossi are title contenders. One of them will finish in the top five even if Andretti is still not quite at Penske level. I also believe that Graham Rahal and Rahal Letterman Lanigan Racing are a combo now fully ready to take on the biggest teams across a whole season.
Tom Errington: IndyCar has traditionally had a strong "best of the rest" and with a new aerokit to mix things up, at least initially, and lower costs going forward, now looks a good time for those teams to take the next step. Graham Rahal has always maximized the one-car line-up, but with Indianapolis 500 winner Takuma Sato onboard it should help raise the team. A similar change at Schmidt Peterson Motorsports, bringing in ex-Mercedes DTM driver Robert Wickens, should help Hinchcliffe be a more consistent threat.
