With the 2014 Mercedes-Benz E 63 AMG now offering as much as 430kW in ‘S-Model’ trim, the 412kW of the BMW M5 is starting to look a little feeble, at least in terms of bragging rights (we doubt most owners would be able to tell the difference).
To rectify the issue, BMW is planning an upgrade for the M5, which Car and Driver is reporting will boost output to 423kW. The upgrade will likely arrive as a Competition Package and is said to be developed for both the M5 and M6.
Being part of a Competition Package, expect a host of other upgrades including new wheels, brakes and tires. Revised suspension and a number of minor aero tweaks are also likely.
Cars fitted with the Competition Package are expected to deliver 0-60 mph (0-97 km/h) times around 0.1 of a second quicker than those with the current 412kW rating. This could mean 0-100km/h in 4.2 seconds for local models.
For those at home counting, that’s still 0.6s behind the new all-wheel-drive E 63 AMG S-Model available in left-hand drive markets. Look for the M5 and M6 Competition Package to be offered overseas by the mid-year, while the option is yet to be confirmed for Australian models.
"We would absolutely be interested if such a package proves suitable for our market, but cannot confirm any M5 or M6 performance boosts at this stage", BMW Australia's Corporate Communications boss Lenore Fletcher said.
"Australia has the highest per-capita takeup rate of BMW performance variants in the world."
Ms Fletcher suggested the package could join the range when the M5 and M6 range is refreshed locally in the fourth quarter of this year.
Note, the power wars aren’t likely to end there. Audi’s RS 6/RS 7 duo is tipped to receive their own ‘Plus’ upgrades that could see output reach as much as 447kW. However, no official word of their release has been mentioned.
