据外媒最新报道,法拉利将在明年日内瓦车展发布666马力458 M。该车外观将获得升级，预计采用渐进式改款，突出空气动力学性能。该车内部编号为“142M”，作为458 Italia的后继车型，该车将搭载V8双涡轮增压引擎，为了能在中国市场销售时避免因排量太高被征收更多税，其排量低于4升，而现行版由于排量4.5升导致销售受到影响。该引擎很大程度上基于加利福尼亚T的3.8升引擎，但功率提升至497千瓦/666马力，超过主要竞争车型迈凯伦650S的478千瓦/641马力，扭矩达到745牛米，比650S提升68牛米。该引擎压缩比达到12:1，由于采用了法拉利的“ion” 爆震检测系统，可以自动调整每个气缸的燃烧条件。与引擎搭配的是格特拉克七速双离合器变速箱。

 

Ferrari 458 M coming to Geneva Motor Show with 666 bhp twin-turbo V8

A new report indicates the Ferrari 458 M will be unveiled next year at the Geneva Motor Show with as much as 666 bhp.

 

Internally codenamed "142M", the Ferrari 458 Italia successor is believed to come with a twin-turbo V8 engine that will have a displacement of less than four liters in order to comply with the Chinese tax threshold which has greatly affected sales of the current model that packs a 4.5-liter V8.

 

The new motor will be largely based on the California T's 3.8-liter unit and according to Autocar it could be tweaked to develop 666 bhp (497 kW) which would be more than main rival McLaren 650S that has 641 bhp (478 kW). Chances are the engine will have a 12:1 compression ratio and will benefit from the company's "ion" knock detection system which can automatically adjust combustion conditions for each of the eight cylinders.

 

Torque is estimated to stand at more than 550 lb-ft (745 Nm) which would be 50 lb-ft (68 Nm) more than the 650S. To cope with the extra power, Ferrari's engineers will have to make some upgrades to the dual-clutch Getrag seven-speed gearbox which will likely get uprated internals and/or an additional gear.

 

Scheduled to debut March next year at the Geneva Motor Show, the Ferrari 458 M (name not confirmed) will adopt an evolutionary styling with an emphasis on being more aerodynamically efficient.
