Today marks the start of the pre-season testing, which is quite different compared to how it used to be in that we're seeing most of the cars officially for the first time today rather than the 3-4 week period of unveiling that most teams used to do a few years ago (that some still do). McLaren-Honda: Jenson Button & Fernando Alonso stay put. Still without a title sponsor, which is making them lose out on about £20m per year. Appears to be sticking with Ron Dennis as team principle, and Eric Boullier as Racing Director. Obvious concerns over pace/reliability, Ron Dennis refused to make predictions about the 2016 season. Scuderia Ferrari: Sticking with Sebastian Vettel and Kimi Raikkonen Quick in pre-season testing. Most likely the biggest competitors to Mercedes in 2016 Red Bull-Tag Heuer: Sticking with Daniil Kyvat and Daniel Ricciardo Infiniti has dropped out as a title sponsor, meaning the purple colour has gone from the livery. Matt Black finish on the Red Bulls, it stands out rather well on TV. The Renault engines are labelled as Tag-Heuer engines, and are expected to develop well throughout the season. Christian Horner does not expect RB to be challenging Mercedes for pole. Scuderia Toro Rosso: As seen by the scuderia in the name, Toro Rosso will now be running Ferrari engines, different to their sister team RB. Sticking with Max Verstappen and Carlos Sainz JR. Due to differences in the size of the ferrari and renault engines, the Toro Rossos will be more different than in previous years. Force India: Staying with Nico Hulkenberg and Sergio Perez Had a fairly strong 2015, has potential to grab some points in 2016. Manor Racing: The old Marussia F1 team has rebranded to become Manor Switch from Ferrari engines, to Mercedes power. Management reshuffle, Booth and Lowdon both gone. Dave Ryan is the new racing director Driver reshuffle, Will Stevens and Roberto Mehri out, Rio Haryanto and Pascal Wehrlein in. They're a bit more confident that the MRT05 will be quite competitive. Haas F1: New team for 2016 Will be using Ferrari power (and many other Ferrari components). Esteban Gutierrez and Romain Grosjean will be the drivers. Former Jaguar and RBR technical director Gunther Steiner will be the team principle. Gene Haas, team owner, expects the team to be a backrunner for a few years much like his other motorsport teams, before doing well. Williams: Felipe Massa and Valtteri Bottas will remain drivers. Susie Wolff no longer a reserve driver, replaced by Alex Lynn They're being quite careful about how optimistic they are for the upcoming season, but hopefully they'll continue to bite at the rear of the front runners if not more. Sauber: Maruc Ericsson and Felipe Nasr have kept their seats. Not much else to report on the Sauber front..... which hopefully isn't indicative of their upcoming season. Renault: Formerly Lotus F1 (Which was formerly Renault). Grosjean has moved to Haas, Maldonado has lost his seat in F1. Jolyon Palmer (GP2 Champ) and Kevin Magnussen are the confirmed drivers. Bob Bell is the chief technical director and Frederic Vasseur is the racing director. The RS16's livery is meant to be temporary? I'm sure I've heard that they're waiting on a title sponsor similar to McLaren. Mercedes F1: Hamilton and Rosberg have kept their seats. Still consists of the Niki Lauda/Toto Wolff/Paddy Lowe trio as management. The car is looking quick as expected. ---------------------------------------------------------------------------------------------------------------------- So what's there to know? - The cars appear to have gone on a bit of a diet at the rear, not necessarily lighter, they just appear to have a skinnier arse. - The noise is meant to be a huge improvement, 10-15% louder. - The Ferrari is meant to be closer to the Mercedes than in the previous 2 years, but where will Williams come? - WIll Manor be as competitive as they've let on?
