The 2013 model year brings some updates for the Buick Regal sedan, namely a new automatic transmission option and the discontinuation of the 2.4-liter base model.

The new Aisin AF40 six-speed automatic with Driver Shift Control will be available as a no-cost option instead of the existing six-speed manual gearbox on the 270HP Regal GS. Buick says that acceleration matches the manual with an estimated 0-60 mph sprint time of 6.7 seconds.

In one of those embarrassing moments than can haunt you for a very, very long time (especially when the mishap occurs in front of a crowd with hand held cameras…), a driver of what looks like a modified second-generation Buick Regal Coupe from the early 1980s, gets ready to impress by beating his rival in a drag strip race.

And then it happens; as he leaves the line in full force the seat breaks and he falls back… Watch the funny incident in the video after the jump.

Following a similar announcement in the USA earlier this month, General Motors has now released pricing for the 2012 Buick Regal eAssist and Regal GS in Canada.

The new Regal with GM's eAssist micro-hybrid technology that's good for 8.3 lt/100km in the city and 5.4 lt/100km on the highway, will start at CA$34,190, while the sporty Regal GS fitted with a 270-horsepower 2.0-liter turbocharged engine will start at $42,345.
