[3] Intended to halve costs through control parts, the series mandated a standardised chassis and roll cage combination designed to attract new manufacturers to compete alongside the existing Holden and Ford products, whilst maintaining the popular 5.0L V8 engines – the base platforms would then be homologated to achieve technical parity, and teams allowed to develop certain components on top of that.

[1] Originally 6.2L, it was destroked to the category-mandated 5.0L, and – uniquely for V8 Supercars of the period – was initially developed with a flat-plane crank, fly-by-wire throttle, dual butterfly valve intakes and electric power steering.

[15] Lee Holdsworth and Tim Slade in the satellite James Rosenberg Racing car were retained, whilst Mercedes factory driver Maro Engel replaced Shane van Gisbergen; the New Zealander had 'retired' at the end of the previous season and controversially defected to Tekno Autosports, resulting in a legal battle.

[20][21][22] The team were granted permission to further test Engel's car at Calder Park Raceway with Craig Baird behind the wheel to troubleshoot electronic issues, before Slade endured two failures related to the engine and driveline at the non-championship Australian Grand Prix event.

[27][28] Holdsworth then went on a streak of five-straight DNFs across the Darwin, Townsville and Ipswich events due to a variety of crashes and mechanical issues, however Slade managed two eighth-place finishes in the same period and had run as high as second in the final race at Queensland Raceway.

[34] Prior to the Sandown 500, Tobias Mörs – head of vehicle development at Mercedes-AMG – stated that the brand were "unhappy" with the progress of the car, and that the team had to win races for their contract to be renewed at the end of 2014; but conceded that Mercedes had "underestimated everything in the series".

[45][46] Holdsworth and Slade finished 20th and 22nd respectively in the drivers' championship, with Engel 28th and last of the full-time competitors – the German was dropped at seasons' end due to budgetary reasons, despite still having a year left on his contract.

[54][55][56] Inconsistent outings followed in Auckland and Perth, before a failed sponsorship deal with Dogecoin led to AMG Customer Sports branding appearing on the cars in Darwin and Townsville – support from Affalterbach that was vindicated after Davison scored his first podium for the team in Race 20.

[57][58][59] During the mid-portion of the season, Erebus and AMG expressed that "extremely positive" discussions were taking place about extending customer support into 2015, amid speculation that the team were evaluating a switch to Volvo.

[63] The team suffered a torrid weekend at Sandown, with Holdsworth walking away from a high-speed crash at the end of the back straight caused by a mechanical failure, whilst the Davison brothers finished down 21st.

[72] Ashley Walsh, who finished third in the 2014 Dunlop Series, made his main-game debut alongside Davison, whilst Ross Stone left his position as general manager and Campbell Little was brought in as an advisor.

[89] Erebus emblazoned their cars with anti-domestic violence messages for Sandown following a spate of incidents in Australia during the preceding week, however Walsh and Le Brocq only managed 19th whilst the Davison brothers finished 7 laps down with a starter motor problem.

[96][97][98] Due to the cost of development and lack of progress, Erebus abandoned the E63 AMGs at the end of the 2015 season and replaced them with Walkinshaw Racing-built Holden Commodore VFs for 2016.
