There’s a lot to say about Mercedes-Benz’s US-bound A-Class. It’s a car of many firsts: The first A-Class model to appear in the US when it hits dealerships later this year; the first A-Class sedan, well, ever (earlier Euro-spec models were glorious hatchbacks). And since we’ve been dutifully tracking the ways our cars are becoming more like smartphones, it’s important to note that this is the first vehicle to feature Mercedes’ voice-driven MBUX interface.
