The 2012 Dunlop MSA British Touring Car Championship was a multi-event motor racing championship for production-based touring cars held across England and Scotland. The championship features a mix of professional motor racing teams and privately funded amateur drivers competing in highly modified versions of family cars which are sold to the general public and conform to the technical regulations for the championship. It is one of the most popular domestic motor racing series in the United Kingdom, with an extensive program of support categories built up around the BTCC centrepiece. It was the 55th British Touring Car Championship (BTCC) season.

This was the second season that cars conforming to the Next Generation Touring Car (NGTC) specification were allowed to compete and the third and final season of the phased transition from the Super 2000 specification. The season will see teams compete with car chassis built to either NGTC or S2000 specification. Teams can choose to run the NGTC turbocharged engine or the Naturally Aspirated engines. The phased transition from S2000 to NGTC means that the organising body, TOCA, will maintain a performance equalisation between the two chassis specifications. They achieved this by monitoring the turbo boost pressures of all cars throughout the season, adjusting the pressure levels after every two rounds to maintain performance parity between all cars. The amount the turbo was adjusted was determined via a mathematical calculation based on race performance. The season was also the first season without cars built to the BTC Touring specification since 2000. A revised championship points system was introduced for the 2012 season, in which the top 15 cars scored championship points instead of the top 10 previously.

2011 series champion Matt Neal defended his title along with Honda, who defended and retained both the Teams' and Manufacturers' championships. Reigning Independent Drivers' champion James Nash didn't defend his title after graduating into the World Touring Car Championship. Triple Eight Race Engineering were the reigning Independent Teams' champions, but as they entered with returning manufacturer MG, they were ineligible to defend the Independents' championship.

Gordon Shedden claimed his first BTCC Drivers' title at the penultimate race of the year, Round 29 at the Brands Hatch GP circuit. Andrew Jordan claimed his first Independents' title during the same race.

Season report

Round One (Races 1, 2 & 3) — Brands Hatch Qualifying saw Dave Newsham secure his maiden pole position in the Super 2000 ex-888 Vauxhall Vectra. Defending champion Matt Neal secured the other front row sport in the brand new NGTC Civic. Race one, was won by Rob Collard in his BMW from Neal after Newsham and Jason Plato came together at the top of Paddock Hill Bend. Race two, saw the first win for a car built to NGTC rules. The Honda Yuasa Racing Team's Civic with Neal at the wheel prevailed after a race long battle with Plato's brand new MG6. Plato won an incident filled Race three which saw the race red flagged after a seven car pile up at Druids Bend, caused by oil spilled on the track from the damaged Ford Focus of Mat Jackson.

Round Two (Races 4, 5 & 6) — Donington Park MG scored their first pole position since returning to the BTCC with Jason Plato during qualifying. Mat Jackson led home the Honda pair in race one, with Gordon Shedden leading Matt Neal and Mat Jackson home in race two, making five different winners from four teams in from the first five races of the season. However, this was not to continue as after a controversial final race of the day, where at the final corner Plato collided with Shedden, sending both cars of the track. This led to Mat Jackson crossing the line first, from Plato, then Shedden. However, Jackson's Focus was excluded from the race after a turbo boost irregularity and Plato was given a two-second penalty for his contact with Shedden, promoting Shedden to the race win.

Round Three (Races 7, 8 & 9) — Thruxton Prior to the event, Thorney Motorsport announce that, due to lack of funds for both racing and development of their new NGTC Insignia, they were not going to take part at Thruxton. A damp qualifying gave Andrew Jordan and Pirtek their first pole of 2012. But, Saturday success would not convert into Sunday glory as a very wet race one saw Jordan slide into Jason Plato at the first turn, sending Jordan into the wall and out of the race. The race came to an abrupt end, when Liam Griffin crashed his car at turn one, causing a red flag. Mat Jackson therefore took his second win of the season, ahead of Dave Newsham and a recovering Plato. Weather condition had worsened for race two and was therefore started behind the safety car. It was Gordon Shedden who mastered the weather to come through the field to score his third win of the season. By the final race of the day, the condition had significantly improved, but it was still Shedden at the front leading home his teammate for a Honda one-two. All three fastest lap points at Thruxton went to Shedden, showing his speed in the tricky conditions.

Round Four (Races 10, 11 & 12) — Oulton Park In the week leading up to round four, Rob Austin Racing revealed that, former FIA Formula Two Championship driver Will Bratt would make his championship debut in the team's second car. However, Rob Austin would miss the event due to ongoing repairs to his car, after a big crash at Thruxton. A circuit with damp patches made for an exciting qualifying session with several cars drifting and sliding off the track as they went round Cascades. The session belonged to Jason Plato though, setting a time 0.077 seconds faster than rival Matt Neal, making Plato the first repeat pole sitter of the season. But the pole sitter would not make it past turn one after Plato's car had a suspension failure on the warm up lap to the grid, causing his MG to be pushed off the grid before the race even begun. That left the door open for Matt Neal to take the race one win after passing the fast starting Rob Collard. The second race of the day, saw Neal's Honda teammate take top honours ahead of Pirtek's Andrew Jordan, with a recovering Plato, who started at the back of the field, finishing third. The final race of the day, saw Neal once again step onto the top step of the podium, making Honda Yuasa Racing the winning team from seven of the last eight races.

Round Five (Races 13, 14 & 15) — Croft In the buildup to Croft, Paul O'Neill announced he would make a one-off return to racing in Speedworks Toyota Avensis, substituting for Tony Hughes. The point for pole position went to Matt Neal for the first time this season. Again, as at Oulton Park, Jason Plato was pushed off the grid in an exciting race one which saw Neal recover from a poor start to take his fourth win of the season ahead of eBay Motors BMW of Rob Collard and the second Honda Yuasa Civic of Gordon Shedden. The Honda teammates reversed their positions in race two, with Shedden finishing ahead of Neal. A fantastic drive from Rob Austin, in his NGTC Audi A4, saw him take the last step on the podium. In a reverse of fortune from the first race, Plato took the race three win after some intense on track action. Liam Griffin brought out the safety car, after crashing his Redstone Racing Focus into the wall, causing an engine fire. Andy Neate led the early part of the race, ahead of his MG teammate Plato. Neate, however, was unable to fend Plato off and subsequently fell back down the order, giving Plato the race win from Tom Onslow-Cole and Andrew Jordan.

Heading into the mid-season break, Matt Neal leads the drivers’ championship by a single point from his Honda teammate Gordon Shedden, with MG's Jason Plato in third, 29 points behind the leader. Honda Yuasa Racing hold a strong 213-point lead from eBay Motors in the teams championship as well as a 123-point lead from MG in the manufacturers' championship. Pirtek's Andrew Jordan is the leading Independent driver and eBay Motors, the leading Independent team.

Round Six (Races 16, 17 & 18) — Snetterton

During the mid-season break leading up to Snetterton, Team HARD. announced that Tony Gilham would step aside to allow American SCCA World Challenge driver Robb Holland to make his series debut with the team. Holland will be the first driver from the USA to compete in the BTCC since Bill Gubelmann in 1975. Following on from this, Thorney Motorsport announced that they would return at Snetterton with Gilham at the wheel, after more extensive development of the Insignia. Liam Griffin pulled out of the meeting due to business commitments linked to the 2012 Summer Olympics, whilst a final surprise was the unveiling of a new NGTC Ford Focus ST, built by Motorbase Performance, to be driven by Mat Jackson.

Drama started almost immediately, when Gordon Shedden's Civic caught fire in the first free practice, causing the Scotsman to set no competitive time in qualifying, which belonged to Frank Wrathall, setting his maiden pole position and a new course record. Race one though saw Jason Plato win after starting second on the grid and taking the lead into the first turn. Wrathall managed to bring his Dynojet Toyota home second. Third place went to Andrew Jordan who narrowly beat Dave Newsham to the line after the two drivers came together several times during the final lap. However, Newsham would later be disqualified after being found underweight. This promoted Matt Neal to fourth, whilst his teammate Shedden removed from last on the grid to seventh. Debutant Holland failed to finish the race after crashing at turn one with Adam Morgan. Race two saw old rivals Plato and Neal once again come together amid frantic action for the win. Plato had led from the start; however Neal took the lead after sending the MG into a large slide coming through the penultimate corner. At the next turn, Plato returned the favour sending both Neal and himself off the track. This promoted Pirtek's Andrew Jordan to his first win of the season and Gordon Shedden up to second with Plato and Neal finishing third and fourth respectively. The reverse grid race three saw the ex-888 Vectras of Lea Wood and Dave Newsham lead the early laps in first and second respectively, until lap four, where Newsham took the lead where he stayed till the end, taking his first BTCC win. A career first podium wasn't on the cards though for Wood, after a gearbox failure with only three laps to go. This left Tom Onslow-Cole with second place and Shedden crossing the line in third place ahead of Jason Plato. However, post-race scrutineering found that Shedden's Honda had been over-boosting, thus disqualifying him from the results. This promoted Plato to third, whilst Neal recovered from and early spin, which sent him to the back of the field, to finish eighth.

Round Seven (Races 19, 20 & 21) — Knockhill

In the run up to the BTCC's only Scottish round, Paul O'Neill announced he would deputise at Speedworks Motorsport, once again substituting for Tony Hughes. Robb Holland again replaced Tony Gilham at Team HARD., whilst Thorney Motorsport, Rob Austin Racing, AmD Tuning.com and Liam Griffin announced they would not be making the trip north of the border, each citing different reasons. Jason Plato took the pole position after a wet qualifying session, with the eBay Motors BMW of Rob Collard starting alongside. Árón Smith took a career best third place with his Redstone Racing Ford Focus.
