You're thinking of McLaren. "McLaren Racing" in fact.

Maclaren make strollers. Umbrella-style strollers to be specific. They're arguably one of the best and certainly the most well known premium umbrella stroller brand, but an umbrella stroller isn't necessarily a replacement for a stroller system or multi-function stroller. They can make a good second stroller for those families that have the need, means or desire though.

The most obvious difference compared to a combination-type product is that there's only a single riding position, sitting upright. If was traveling a lot on public transit with a 1+ year old, this would definitely be the stroller I'd want to use. Especially if you're not going to deal with uneven terrain. For a lot of urban walking however, something like the others that have been mentioned (Quinny, Bugaboo or Stokke) would be a lot more comfortable and convenient for both parent and child.

Strollers and stroller systems are probably where I focused most of my own baby-centric product research time.
