BMW tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

Electric living with a BMW i3

Rarely in the 27-plus years I've been testing and writing about cars has any vehicle changed this much from my initial impression until I was later able to spend more time in one. Nearly two years ago, I got a brief test drive of the then-new BMW i3 EV on a selection of both flat and hilly, curvy roads west of Los Angeles the day before LA Auto Show press days. My impressions at the time were mixed: polarizing exterior and interior designs but roomy, easily accessible rear cabin; great twisty road handling but somewhat brittle rough-road ride; good performance but annoyingly strong (always on) regenerative braking. And there was no opportunity to test one with the optional range-extender (which BMW calls a "REx") engine. So I wanted an extended experience in a REx-equipped i3, and recently got one. And, I'm here to report that, driving it for a week like I owned it, the quirky i3 soon won me over. The quirky i3 soon won me over. The $42,400 BMW EV's unique, lightweight "LifeDrive" architecture features a Carbon Fiber Reinforced Plastic (CFRP) passenger cell on an all-aluminum chassis. Powered by a 22-kWh lithium-ion battery pack, its 170-hp AC synchronous motor spins out a healthy 184-pound-feet of torque through a single-speed transmission and offers three drive modes: Comfort, Eco Pro (which BMW says adds roughly 12 percent of range) and Eco Pro+ (another 12 percent). The optional rear-mounted 647 cc (0.65-liter) in-line 2-cylinder REx engine drives an electric generator, never the wheels. It increases the sticker price to $46,250 and curb weight from 2,860 pounds to 3,130 lb., and that 270-lb. weight penalty reduces its electric-only range from 81 to 72 miles and EPA-rated combined (gas-equivalent) fuel economy from 124 to 117 MPGe, and slows its 0-60-mph acceleration from 7.0 to 7.8 sec. But it nearly doubles the i3's official EPA-rated total range from an EV-only 81 miles to an EV-plus-gasoline 150 miles. The i3 arrived (from roughly 90 miles away) with its battery depleted but an indicated 75 miles of gas-powered range remaining. Wanting to experience it REx-only at first, I drove it on a 9.6-mile local trip and found little difference in sound or performance from what I recalled from that California battery-only test drive. When I returned home, however, the indicated gas range was just 55 miles, so I had used 20 miles of projected range in less than 10 local miles. My initial impressions were good, with a few quibbles.

Dinan S3-R BMW 1M Coupe

I nearly shed tears a few years ago upon learning that BMW was only planning to produce a very limited quantity of its then-new 2011 1 Series M Coupe. In simplest terms, the two-door was a 1 Series fitted with a modified version of the automaker's twin-turbocharged 3.0-liter inline-six, and the running gear (gearbox, driveshaft, axles) from contemporary M3 models. It was also a return to form for the brand. Aggressively short and stubby in stature but packing telltale flared wheel arches that hinted at its potential, the four-seater was a spiritual successor to the original (and much loved) E30 M3 from decades earlier.
After spending a day with the original high-performance 1 at New York's Monticello Motor Club, I declared, "The little coupe with the big flares is old-school retro cool and deliciously fun to drive ... the new BMW 1 Series M Coupe doesn't target boy-racers, it targets enthusiasts." Yet sadly - and despite strong demand - BMW limited the model's production to just one year. All told, only 740 units made it to the States, and each was gobbled up at a starting price of $46,135, a price tag history will show to be a bargain.
Since I had little hope of even driving one again, I deliberately pushed all memories of BMW's 1 Series M Coupe from my mind - until my phone rang recently. On the other end was a representative from Dinan Engineering who wanted to know if I would be interested in driving the company's new S3-R BMW 1M. A quick Google search revealed it to be a heavily modified version of the discontinued 1 Series M Coupe. As if they needed an answer...
