That's not much more than usual. A Honda Accord has 270HP. A Toyota Camry has about 270 as well.
It's an economy car. Economy cars are always available with manual transmissions because they cost $1000 less. They are more economical if you want to think of it like that.
Same mileage but they're virtually undrivable. Put 3 people in a Corolla and the thing will jump gears between 3 and 4 all the time. The instruction manual and people in AT Garage both say one should lock it out of overdrive when it does this, and that drops the gas mileage by 10%. Cars with manual transmissions never need to be restricted like that. In trucks with automatic transmissions, the instruction manual will often say never to tow anything in overdrive. Such a rule does not exist with manual transmissions; you can run a manual in overdrive all you want and it won't screw up.
