In less time than it takes some computers to power up, Wendy's can get a customer in and out of its drive-through.
The fast-food chain needed 129.75 seconds to clear a car through its queue last year — 16 seconds better than 2010, and faster than any other major chain, according to an annual report from QSR magazine.
Chick-fil-A takes longer — 190.06 seconds — to do the same. But the chicken restaurant has the best accuracy ratings, getting 92.4 percent of drive-through orders correct.
Less impressive: Burger King, which requires 201.33 seconds to serve car-bound customers and also has the worst precision record. The chain correctly delivers 83 percent of its drive-through orders, down 6.7 percentage points from 2010.
QSR, which focuses on the quick-service restaurant industry, paired up with Insula Research to survey seven fast-food joints on their drive-through performance. The outdoor service stations can account for up to 70 percent of sales at some chains.
Wendy's was the only chain to improve its average service time last year, and even then, it was slower than the 116.2-second record it set in 2003. The chain has less than two cars in its line at an average point; Chick-fil-A has the most, with more than five.
Chick-fil-A was also deemed to have the best customer service, with 92.4 percent of its drive-through units classified as delivering a pleasant experience or better. Burger King, with 61.7 percent, had the lowest percentage of pleasant encounters.
