McLaren MP4-12C Power Raised to 625hp for Autumn 2012
McLaren will increase the MP4-12C’s output to 625hp this autumn, with changes centred on ECU tuning and a new exhaust, while fuel economy and emissions remain unchanged.
McLaren will raise the power output of its MP4-12C supercar to 625hp this autumn, bringing a modest but notable increase over the current 592hp figure. The change is expected to arrive as part of an update for the 2013 model year. The extra 33hp comes from revised ECU software and a new exhaust system. According to McLaren, the update will not affect fuel consumption or CO2 emissions, maintaining the car’s efficiency figures despite the added performance. This approach allows McLaren to sharpen the MP4-12C’s appeal against rivals such as the Ferrari 458 Italia without incurring a penalty under emissions-based taxation schemes.
McLaren MP4-12C Gains Power Boost for Autumn 2012
- MP4-12C power rises from 592hp to 625hp for autumn 2012
- Upgrade achieved via ECU remap and new exhaust
- No change to official fuel consumption or CO2 figures
- 3.8-litre twin-turbo V8 engine remains at the core
- Competes with Ferrari 458 Italia
- Update coincides with arrival of 12C Spider
Technical Changes for the 2013 MP4-12C
The current MP4-12C uses a 3.8-litre twin-turbocharged V8, delivering 592hp at 7,000rpm and 443lb ft of torque between 3,000 and 7,000rpm. With the new ECU calibration, peak power increases to 625hp. McLaren has not detailed any mechanical changes to the engine internals, suggesting the boost is delivered entirely through software and exhaust tuning.
Performance figures for the updated model are not yet confirmed, but the outgoing version accelerates from 0-62mph in 3.3 seconds and reaches a top speed of 205mph. The additional power is likely to trim the acceleration times slightly, though McLaren has not released revised numbers at this stage.
Market Context and Model Positioning
The power increase arrives as McLaren prepares to launch the 12C Spider, the open-top version of the MP4-12C. The update is expected to keep the coupé competitive with newer rivals and maintain interest as the company develops its next flagship. Pricing for the MP4-12C started at $231,400 in the US at launch, placing it in direct competition with the Ferrari 458 Italia and Lamborghini Gallardo.
| Model | Power Output |
|---|---|
| McLaren MP4-12C Coupé (2013) | 625hp |
| McLaren MP4-12C Spider (expected) | 625hp |
| Ferrari 458 Italia | 570hp |
| Lamborghini Gallardo LP560-4 | 552hp |
The 12C Spider is expected to feature the same power output as the updated coupé, helping to align the performance of both body styles as the drop-top variant enters the market. This move is likely aimed at ensuring buyers of either version receive comparable performance, particularly as the Spider will appeal to those seeking open-air driving without sacrificing speed.
Background: The MP4-12C and Its Rivals
The McLaren MP4-12C was introduced as a direct competitor to established supercars like the Ferrari 458 Italia and Lamborghini Gallardo. Since its launch, the MP4-12C has been recognised for its advanced engineering, lightweight construction, and impressive performance. The 3.8-litre twin-turbocharged V8 engine has been central to its appeal, offering a blend of high power and relative efficiency for the segment.

With the 625hp update, McLaren aims to maintain the MP4-12C’s competitive position as new models and refreshed versions of rivals enter the market. The incremental power increase, achieved without sacrificing emissions or fuel economy, reflects the brand’s focus on both performance and technological advancement.
Availability and Further Details
McLaren has not announced whether existing MP4-12C owners will be offered the upgrade. More information is expected closer to the autumn launch. The company is likely to reveal full technical specifications and revised performance data as the update approaches its release.
For background on the MP4-12C’s pricing and early market rollout, the model was introduced with a starting price of $231,400 in the United States. This positioned it firmly in the high-performance supercar segment, targeting buyers seeking cutting-edge technology and exclusivity. The forthcoming power boost is part of McLaren’s strategy to keep the MP4-12C fresh and desirable as it continues to compete with established and emerging rivals.
Further updates and detailed figures are expected to be announced by McLaren as the autumn launch nears, providing prospective buyers and current owners with a clearer picture of what to expect from the enhanced MP4-12C.
