McLaren speeds forward, plans 18 launches by '25

McLaren has revealed a rush of new product over the past 12 months and more is coming.

The automaker's Track 25 business plan calls for 18 launches of new models or derivatives by 2025 at an investment of $2.1 billion.

McLaren is exploring a full-electric vehicle that could arrive by 2025. An EV is a key part of its plan to convert its fleet of sports cars and supercars to hybrids by then.

For now, the British automaker continues to bolster its lineup with the Senna and 600LT headlining this year's additions.

570: McLaren's entry lineup expanded late last year when sales of the spider variant began. The full range of offerings — 570S, 570S Spider and 570GT — will soldier on unchanged for the foreseeable future.

600LT: Production of the 600LT (LT stands for Longtail) begins next month and will run for about 12 months. Pricing starts at $242,500 including shipping. The 600LT receives its moniker from a body that is 2.9 inches longer than a 570S coupe. Power is supplied by a twin-turbocharged, 3.8-liter V-8 engine that produces 592 hp and 457 pound-feet of torque. The model sits atop McLaren's Sports Series, which is below the Super and Ultimate series.

720S: The 720S replaced the 650S last year and, along with any future variants, is expected to account for a third of the automaker's annual sales. Starting at $297,100 including shipping, the 720S is positioned as a rival to the Ferrari 488. A spider variant is likely in 2019, followed by a Longtail variant.

Senna: Deliveries of McLaren's track-focused — but road legal — Senna began in July. Production is limited to 500 worldwide and has long been sold out. The hypercar is powered by a 4.0-liter twin-turbo V-8 that produces 789 hp and 590 pound-feet of torque, but weighs less than 3,000 pounds.

The automaker will build 75 track-only Senna GTRs in 2019, calling that variant the "most extreme McLaren car ever."

Speedtail: McLaren's next addition to its top-tier Ultimate Series is known as Speedtail. The automaker says the hybrid, announced in 2016 under the code-name BP23, will be McLaren's fastest and most luxurious model ever. The Speedtail will have a three-seat layout with a central driving position, just like the iconic McLaren F1. The production run is sold out and is limited to 106 units — a nod to the F1's production run. The vehicle will be shown to customers in October before making its public debut by year end. Production will begin at the end of 2019, with the price starting at around $2.1 million.
