Team changes

• Cosworth elected not to build an engine to fit the 2014 generation of regulations. This decision prompted Marussia, the only team using Cosworth engines during the season, to seek out a new engine supplier. They joined Ferrari's customer programme with Ferrari providing the team with both engine and powertrain for 2014 and beyond.
• Toro Rosso secured an agreement with Renault for engines in 2014, ending their seven-year arrangement with Ferrari.
• Williams parted ways with Renault after two seasons, switching to Mercedes power in what the team described as a "long-term deal". The deal came after Renault publicised their intentions to reduce their engine supply to three teams in 2014, before the French manufacturer ultimately settled on supplying four.
• In 2011, former British American Racing team principal Craig Pollock announced the formation of Propulsion Universelle et Récuperation d'Énergie—commonly known by its acronym, PURE—and signalled his intentions to enter the sport in 2014 as a customer engine supplier, with the full support of the FIA. However, the engine programme was eventually suspended in July 2012 due to problems regarding funding, and was ultimately unable to secure any clients for the 2014 season.

  Driver changes

• runner-up Felipe Massa left Ferrari at the end of the 2013 season after eight years racing for the team. He moved to Williams, alongside Valtteri Bottas. Pastor Maldonado, having been replaced at Williams by Massa, moved to Lotus F1, taking the seat vacated by World Champion Kimi Räikkönen. Räikkönen returned to Ferrari, the team he raced for from 2007 to. The partnership of Räikkönen and Fernando Alonso marked the first time since that Ferrari contested a season with two World Drivers' Champions in the team.
• Mark Webber retired from Formula One after twelve seasons, the last seven with Red Bull Racing. He moved to the FIA World Endurance Championship. Daniel Ricciardo left Scuderia Toro Rosso to fill his seat, becoming the second driver to graduate from the team's young driver programme to their premier racing team. Toro Rosso chose 2013 GP3 Series champion Daniil Kvyat as Ricciardo's replacement.
• Sergio Pérez left McLaren after a single season with the team. He was replaced by 2013 Formula Renault 3.5 champion and McLaren Young Driver Programme member Kevin Magnussen. Pérez moved to Force India, where he was joined by Nico Hülkenberg, who returned to the team after one year with Sauber. As a result of the Hülkenberg and Pérez deals, Paul di Resta and Adrian Sutil lost their seats with the team. Sutil went on to secure Hülkenberg's vacant seat at Sauber, while di Resta left Formula One entirely and returned to the DTM series, the series he competed in prior to joining Formula One.
• Kamui Kobayashi returned to Formula One with Caterham, after spending the 2013 season competing in the World Endurance Championship. He was partnered with GP2 Series regular Marcus Ericsson, who became the first Swedish driver in Formula One since Stefan Johansson retired from the sport in. The decision left both Giedo van der Garde and Charles Pic without a drive, and both went on to take reserve driver roles with other teams; van der Garde joined Sauber, while Pic moved to Lotus.
• Susie Wolff joined Williams as a test and reserve driver, with a programme that included participation in selected Free Practice 1 sessions. In doing so, she became the first female driver to take part in a Grand Prix weekend since Giovanna Amati failed to qualify for the 1992 Brazilian Grand Prix.
• On 3 October 2014, Max Verstappen became the youngest driver to participate in a Formula One Grand Prix weekend, driving in FP1 at the Japanese Grand Prix, deputising in place of Toro Rosso's Jean-Eric Vergne.

  Mid-season changes

• In the week before the, Caterham announced that team owner Tony Fernandes had sold his controlling stake in the team to a group of Swiss and Dubai-based investors. Former Midland and Spyker driver Christijan Albers was appointed as team principal, with the team declaring its intentions to continue competing under the Caterham name. Albers was himself replaced by Manfredi Ravetto, who admitted that the sale was necessary to keep the team on the grid. Ravetto was in turn replaced, this time by Finbarr O'Connell, who was appointed when the team was placed into administration ahead of the United States Grand Prix due to a dispute over the team's ownership. The team was later given a dispensation to miss the United States and Brazilian Grands Prix in order to resolve the dispute.
• Three-time 24 Hours of Le Mans winner and 2011 Formula Nippon champion André Lotterer made his Formula One debut with Caterham, replacing Kamui Kobayashi at the Belgian Grand Prix. Under the terms of the deal, Kobayashi returned to the team for the Italian Grand Prix, while Lotterer returned to Super Formula. The team had further planned to substitute Kobayashi for Formula One's most experienced driver in history, Rubens Barrichello, in the United States, Brazilian and Abu Dhabi Grands Prix, but were forced to abandon the plan when they entered administration. The team ultimately put together a rescue package ahead of the Abu Dhabi Grand Prix, but with Marcus Ericsson formally leaving the team ahead of a move to Sauber in, Caterham chose debutant Will Stevens as his replacement.
• Alexander Rossi was entered for the Belgian Grand Prix by Marussia as a replacement for Max Chilton. However, following the first practice session, Chilton was reinstated as the team's racing driver, and Rossi only participated in the practice session. Rossi was later nominated as Jules Bianchi's replacement for the Russian Grand Prix, but the entry was ultimately withdrawn out of respect for the critically injured Bianchi.
• Jules Bianchi suffered a serious head injury in a crash at the Japanese Grand Prix, remaining hospitalised and in a coma until his death in July 2015. Marussia decided to withdraw their second entry for the Russian Grand Prix, Alexander Rossi, out of respect for the Frenchman. Faced with their own financial problems, the team was also granted a dispensation to miss the United States Grand Prix. One week before the Grand Prix, Marussia followed Caterham into administration.

  Calendar

Calendar changes

New and returning races

• Red Bull reached an agreement with Bernie Ecclestone to revive the Austrian Grand Prix after a ten-year absence from the calendar. The race was held at the Red Bull Ring, which previously hosted the Austrian Grand Prix in, when the circuit was known as the A1-Ring.
• The calendar saw the introduction of the Russian Grand Prix with the race staged at the Sochi Autodrom near the end of the season. The race took place on a street circuit constructed around the Sochi Olympic Park. It was the first Russian Grand Prix in a century, and the first time the country had ever hosted a round of the Formula One World Championship. The International Olympic Committee had cautioned that it would use its power to delay the race until 2015 if it felt that construction of the circuit and facilities were disrupting preparations for the 2014 Winter Olympic Games, but this proved not to be an issue.
• The Hockenheimring returned to the calendar to host the German Grand Prix, in keeping with the event-sharing agreement first established in with the Nürburgring for the two circuits to host the Grand Prix in alternating years. The Hockenheimring last hosted a Grand Prix in.
