The annual Goodwood hill climb has traditionally served as a venue that manufacturers use to showcase for their latest hardware. As a general rule of thumb, an automaker’s confidence in their vehicle’s performance prowess is proportional to how hard they plow through the course – some luxury automakers will take a leisurely stroll up the track, while others will use the hill climb to billow out some tire smoke and show off some other shenanigans.

But when it comes to track day car builders like BAC, if we use that metric to gauge how serious the company is about performance, it’s pretty clear from the footage above that they’re definitely not screwing around.

The revised Mono made its public debut at the event with racing driver and BAC test driver Oliver Webb at the wheel. For 2015, the Mono has been updated with a larger dry-sumped 2.5 liter motor, up from 2.3 liters of the previous car. As a result, the Mono now makes 305bhp and 227 pound-feet of torque, a substantial improvement from the previous 280bhp and 206 lb-ft. A Hewland FTR six-speed sequential transmission allows the driver to manage the cogs.

Although the revisions also see the Mono gain nearly 90 pounds of weight, with the added grunt of the revised motor, the BAC Mono can now get from 0-60 mph in a brief 2.8 seconds on its way to a 170 mile per hour top speed. Watch the single seater devour the Goodwood road course at 10/10s in the clip above.
